FCC ID: 2APTN-TERTILL001 Solar powered weeding robot for home gardens

Tertill Garden Weeding Robot Owners Manual Model T1 Dear Backer/Tertill Owner, Thank you. Tertill exists because of you. Your interest, support, and patience made it possible for the team at Franklin to turn our dream into reality. We are grateful. Now Tertill can begin to reduce herbicide use, increase home food production, and ease the lives of gardeners everywhere. The impact of your contribution will reverberate far beyond your home garden!

But were not done yet. Tertill is only just hatched and has much to learn. We at Franklin have done our best to think through all the situations Tertill might face, program responses, and test extensively. But as Tertill makes its way into the world, its cumulative hours of use will far exceed the time weve spent testing. Tertills in the field will discover situations and problems we havent foreseen. Thats where you come in. We need your help to make Tertill better. If your Tertill does something unexpected, if it gets stuck or does anything youd rather it wouldnt, please tell us. You can email a description of your observations and optionally add photos and (brief) videos to: support@franklinrobotics.com. We will share improvements we make to Tertills software. Thanks again for your help and ongoing support!

www.franklinrobotics.com 4 Quick Start Follow these simple steps to quickly put Tertill to work weeding your garden. Unpack Remove Tertill, the plant collars, wrench, and spare whackers from the shipping box. Establish boundary Make sure that a continuous barrier at least 3 (7.5 cm) tall surrounds your garden. Mark small plants Place plant collars around small or delicate plantswhen in doubt, use a collar. Tertill Owners Manual www.franklinrobotics.com 5 Activate Put Tertill on the ground in the garden. Press and release the power button (red in the drawing). After a few seconds the status LEDs will display a sweeping green pattern. Press the power button again. The display will change to a green, outside-to-center pattern. After another few seconds Tertill will begin to patrol for weeds. If Tertill does not light the LEDs or does not begin to move, it needs to be charged. Either leave it in direct sunlight for an hour or more or use the USB cable to charge the battery (see the USB charging section, page 14). Then press the button again to start the process. Garden Now you are free to do the gardening tasks you enjoy. Tertill will take care of the weeds. Tertill Owners Manual www.franklinrobotics.com 6 Tertill Terms Tertill Owners Manual www.franklinrobotics.com 7 Power button Turns Tertill on and tells Tertill to patrol. LEDs Five colored LEDs give you information about the robot. Solar Cell Provides Tertills power. Molded handle Pick up Tertill with your thumb on top and to the side of the button and your fingers in the handle depression. Speaker Tertill plays tones through the speaker to announce its status and intentions. Extreme camber wheels Tertills wheels are designed to help it move about the garden without tipping over or getting stuck. The wheels also damage sprouting weeds before they can emerge. USB charging port Supplemental battery charging port (no data connection) Serial number The unique serial number of your robot Weed sensor When a weed comes near the sensor Tertill activates its whacker Whacker string Spinning trimmer string cuts weeds before they grow Whacker hub Holds the replaceable whacker string. Obstacle sensors Sensors just inside the robot shell detect plants, wooden barriers, metal fences, and so on. IMU (Internal) Inside the robot a six-axis Inertial Measurement Unit detects the robots tilt and spin rate. Plant collars Used to tell Tertill that that a particular plant is desired. Row collars Used to tell Tertill that that a row of plants is desired. Spare whacker string Replace the whacker string when it wears. Wheel wrench Use to remove and replace wheels if necessary. Tertill Owners Manual www.franklinrobotics.com 8 Robotic Weeding Tertill is single-minded in its pursuit of weeds. It spends 100% of its time in your garden either weeding or collecting energy so it can weed. Come rain or shine your robot will never procrastinate or forget to weed. But, Tertill doesnt have your senses, dexterity, or brain powerit cant weed the way you do. Tertill follows a different strategy, one that doesnt involve pulling weeds or moving in a grid pattern. Tertill attacks weeds in two ways. As it moves and turns in the garden the robots wheels scrub the soil. This damages weed sprouts and can prevent them from emerging. Weeds that do emerge are cut down by the weed whacker. A chopped weed may sprout again but, because Tertill comes back again and again, the weed will eventually run out of stored energy and die. As it navigates the garden Tertill sometimes hugs fences, collars, and plants and sometimes bounces away from such obstructions. Following this strategy over time the robot visits every reachable part of the garden. Tertill Owners Manual www.franklinrobotics.com 9 Garden Tertill needs a couple of features in order to work in your garden. There are also a few things you can do to help it work efficiently. Boundary A physical boundary is necessary to keep Tertill from wandering away. The boundary must completely surround the garden and should be at least 3 (7.5 cm) tall. Almost anything will work, common boundaries include:

Wire fence (chain-link, chicken wire, hardware cloth, etc.) Wrought iron fence Stockade fence Landscaping timber (often used to form raised beds) Brick edging Supplied row collars The fence must be of a height such that Tertill can touch it. Tertill performs best if its obstacle sensors can detect the material from which the boundary is made. These sensors do not detect non-conductive materials like plastic. Plastic fences and plastic edging do confine Tertill but the robot will take extra time to change direction whenever it encounters such a boundary. Slopes A slope that is too steep can cause Tertill to tumble. For that reason Tertill turns away from any slope steeper than about 22 (40% grade). This corresponds to two units of rise for every five units of run. Some crops grow best on mounds of soil but avoid building mounds with slopes greater than 22. Tertill may not visit the top of a mound if the angle it too large. Tertill Owners Manual 10 www.franklinrobotics.com Spacing Tertill must have a path to all parts of the garden. If crops are too close together the robot will be unable to pass between them. As shown in the drawing, leave at least 12

(30.5 cm) between plants. Also, leave 12 between any plant and the boundary around the garden. Row crops should also be planted with rows no closer than 12. If plants tend to be bushy, increase the spacing accordingly. Starting Conditions Tertill is designed to keep weeds at bay. However, it expects to encounter weeds that are short and just sproutingas they are in the early spring. If Tertill is introduced later in the season, after weeds have begun to take hold, some may be too tall to be recognized as weeds or too tough for Tertill to cut down. If this is the case, help Tertill get started by manually removing weeds that are too tall (greater than 1 inch or 2.5 cm) or too robust. Terrain Tertill works most efficiently when the terrain in your garden is relatively smooth. Tertill will do its best when it encounters rocks, ruts, and holes but any time it spends negotiating such hazards is time it wont spend weeding. We recommend removing rocks as much as possible and raking at the beginning of the season to smooth the garden surface. Tertill Owners Manual 11 www.franklinrobotics.com A wide variety of surface types are acceptable to Tertill. This includes bare dirt both soft and packed, sand, gravel, bark mulch and other materials commonly used in gardens. Tertill does not sense cliffs. A cliff is any drop off over which Tertill cannot safely drive. A terraced gardens, for example, has cliffs. If your garden contains a cliff it should be blocked off with a fence or the supplied row collars. Otherwise Tertill may tumble. Tertill Owners Manual 12 www.franklinrobotics.com Operating Tertill Starting After ensuring that there is a continuous boundary around your garden and that your small plants are protected by plant collars, you are ready to start Tertill. Place Tertill on the ground then press and release the power button. After a few seconds the LEDs will display a pattern that sweeps from side to side. This pattern means that Tertill is ready and waiting for your authorization to begin patrolling. Press and release the power button again and Tertill will begin to weed. Unless the battery is badly depleted, you can always force Tertill to begin weeding by pressing the power button in this way. If Tertill does not display the sweeping pattern its battery charge may be too low. There are two remedies for this. Either charge Tertills batteries by letting it sit in direct sun for an hour or more or provide supplemental charging via the USB connection, see below. Stopping You can stop Tertill by pressing and holding the power button (about 10 seconds). If Tertill is patrolling when you want it to stop you can also pick it up by the handle and turn it upside down. Do not pick Tertill up from the front. It may mistake your hand for a weed and act accordingly. Caution: Do not remove Tertill from the garden without pressing and holding the button as described. Otherwise it may wake up and begin patrolling in a place that is not safe, e.g. on a table top. The actions described cause Tertill to enter Hold mode. It will not leave Hold mode and begin patrolling again until it receives authorization to do so, i.e. you must press the power button. This ensures that Tertill will only start weeding when you intend it to do so. Always make sure that Tertill is stopped by following the described procedure before you remove it from the garden. Tertill Owners Manual 13 www.franklinrobotics.com USB charging In normal operation Tertill gets all the power it needs from the sun. However, it is possible to charge Tertills battery using the USB charging port on the robots underside. To use this option: turn Tertill upside down, remove the screw-on waterproof port cap, and insert a micro-USB connector. Your USB power supply should be capable of supplying the 350 mA that Tertill needs to charge. When done, remove the USB cable and reattach the waterproof port cap. Failing to reattach the cap may allow water to enter the robot. Note that the bottom of Tertill is likely to be dirty. Take care not let dirt get into the USB charging port. If the bottom is muddy, rinse with water and dry with a paper towel before removing the port cap. If Tertill is dusty, wipe with a cloth or paper towel before opening. It is important to keep the bulkhead connector and the screw-on port cap clean so that they keep water sealed out. Robot Health Tertill Owners Manual 14 www.franklinrobotics.com Each time Tertill is about to begin patrollingeither because you press the button or the robot decides to gothe LEDs display the health of the robots systems. As shown in the drawing, from left to right the LEDs correspond to the battery, drive wheels, whacker, object sensors (both obstacle and weed sensors), and temperature. In all systems green indicates normal operation. Yellow and red mean different things depending on the system. Battery Yellow means the robot needs to charge but you can command it to run for a short time. Wheels Yellow means one or more wheels are turning slowly. Check to see what is impeding the wheel. Red means that one or more wheels cannot turn at all. Remove dirt or debris that is restraining the wheel. Whacker Yellow shows that the whacker is turning too fast (the string may be too short) or too slow (debris may be wrapped around the shaft). Replace the string or remove debris. Red means the whacker does not turn at all. Remove debris to free the whacker. When you flick the whacker with your finger it should spin around several times. Object sensors Yellow means a weak or unchanging signal. Check the front, sides, and bottom of the robot. A large leaf or other debris that has attached itself to the chassis can prevent the sensors from working properly. Temperature If the temperature of the robot, battery, or motors is too high the robot will not run. Allow it to cool off, after which it should operate normally. All the LEDs flashing red indicates a more serious problem. Contact service@franklinrobotics.com in this case. Tertill Assistance Tertill is designed to live in your garden taking care of weeds and itself. However, Tertill may occasionally need a little help. We recommend that you check the status of your robot at least every few days. Look for the following:

Stuck Has the robot tumbled over or become suck in some way? If it has please move it to a safe area and press the power button to start it running again. If possible, it is also advisable to repair whatever condition caused Tertill to become stuck. E.g. Is there a hole or rut that should be filled or an awkward rock that could be removed?

Tertill Owners Manual 15 www.franklinrobotics.com Mud Depending on weather and soil conditions, caked-on mud can sometimes impede Tertill. Mud sticking to the treads of the wheels usually dislodges once conditions change. However, mud can sometime accumulate beside and under the wheels to such a degree that the wheels cannot turn freely. You can use water from a garden hose to clear mud from the wheels and any other surface to which it sticks. We recommend not using a spray head for this purpose. Also, do not immerse the robot in water and do not spray with a pressure washer. Tertill is sealed against rain but is not intended for full immersion or high pressure spray. Debris Stringy debris can sometimes become wrapped around the wheels or the whacker. Carefully remove such debris, preferably by unwinding it. Only in extreme cases, should you remove the problem wheel using the supplied wrench. Then clear the debris and replace the wheel. Do not over tighten the nut!

Solar cell Clear away any dust or dirt that accumulates on the solar cell to keep it at peak efficiency. Whacker wear The whacker string will gradually wear and shorten. How long the whacker lasts depends on your local weeds, soil type, and prevalence of rocks. When the whacker is shorter than about an inch (2.5 cm) it should be replaced. To replace the whacker string hold the hub with the fingers of one hand then, holding the string near the hub with the other hand, push the string into the hub. In difficult cases pliers might be needed to force the string into the hub. Discard the old string. Reverse the operation to install a new string. Tertill Owners Manual 16 www.franklinrobotics.com Additional whacker strings are available from Franklin Robotics. You can also construct your own from residential grade 0.050 (1.27 mm) trimmer string. To do this, tie a knot in one end of the string, push the string into the hub, and then clip off the end such that about 1.5 (3.8 cm) of string is left protruding from the hub. You can leave a short bit of string (no more than 0.25 or 5 mm) extending from the opposite side of the hub. This will make it easier to remove the string next time. Do not use glue to hold the string in place. Storage If Tertill is to be out of service for a long period, say over the winter, place it in Hold mode as described above and keep it in a dark place. Stored in this way Tertill will not wake up and try to establish a Bluetooth connection. During storage a USB cable should not be connected. Tertill App Tertills smart phone application lets you check Tertills status remotely. The app also provides a way to update the software on your robot. You will find the latest iPhone version on the Apple app store, the Android version is available through Google Play. The Tertill App is an accessory to Tertill and is not necessary for its operation. The robot will remove weeds just as effectively without the app. Tertill Owners Manual 17 www.franklinrobotics.com Bluetooth Bluetooth provides a wireless connection between Tertill and the app running on your smart phone. The app displays the status of any Tertill within range. Note however, that a Bluetooth connection is not available when the robot is charging in the sun or hibernating (see the Operating Modes section, page 21). Frequently Asked Questions Q: Should I bring Tertill indoors when it rains?

A: No. Tertill can handle the same weather conditions as garden plants. Q: Should I bring Tertill indoors if the weather is too hot?

A: This is not necessary. Tertill has a built-in temperature sensors. If the weather it too hot for safe operation Tertill will wait until the air is cooler. Q: Does Tertill charge its batteries while patrolling?

A: Yes, Tertill uses all available energy. However, driving and whacking require more power than the solar cell can supply continuously. So even on a sunny day Tertill will eventually have to stop and collect more energy. Q: Does Tertill work on cloudy days?

A: Tertill uses as much energy as is available to remove weeds. Less energy is available on cloudy days and the robot operates less frequently then. However, weeds need energy too and cannot grow as rapidly during cloudy stretches. Q: Will Tertill work on straw mulch/rubber mulch/sawdust ?

A: Tertill is designed to work with commonly used garden ground-cover material. Q: Tertill leaves tracks in my garden, is that a problem?

A: When the soil is soft and loose, as it may be immediately after tillage, Tertill will leave tracks. After a good rain or after the garden has been watered a few times tracks should be less visible. Q: Will Tertill work on my patio or walkway?

A: Yes, assuming the surface is reasonably flat. But remember that Tertill needs a physical boundary to keep it from wandering away or falling over a cliff. Tertill Owners Manual 18 www.franklinrobotics.com Q: Will Tertill mow my lawn?

A: No. Tertills whacker is designed for small weeds and is not effective against mature lawn grass. Also, Tertills solar cell cannot collect enough energy to cover a typical lawn. Q: Tertill doesnt cut every visible weed. Is something wrong?

A: No. Tertill sometimes drives over a weed without sensing it. But the robot is relentless, it will return again and again. Eventually, it will either grind weeds into the ground with its wheels or chop them with its whacker. Q: Wont chopping weeds as Tertill does just spread their seeds and cause more weeds in the future?

A: No. Weeds, like all plants, must reach a certain level of maturity before they set seed. Tertill attacks weeds at the sprout stage before theyve had a chance to produce and release seeds. Q: How well does Tertill control weeds?

A: To get a idea of how well Tertill works for you, you can conduct a scientific test. Block off a strip of bare land in or adjacent to your gardenleave this soil fallow and out of Tertills reach. By the end of the season youll see what your garden would have looked like had Tertill not been working for you. Q: Is it OK to have two Tertills in the garden at the same time?

A: Yes, multiple Tertills can work in the same space without interfering with each other. Q: Im really curious about whats inside Tertill, can I take it apart?

A: NO! Tertill is assembled at the factory in a way that makes it waterproof under normal circumstances. If you take it apart, then put it back together its likely the waterproof seal will be compromised. If this happens Tertill could drown in the next rain storm. Tertill Owners Manual 19 www.franklinrobotics.com Troubleshooting Symptom LEDs dont turn on Robot turns away from big weeds Small weeds arent cut Cause Battery charge too low Tall plants arent recognized as weeds Weeds too short to be sensed Wait, weeds will be cut when they Remedy Leave robot in sun or charge via USB port Remove tall weeds manually grow and trigger sensor Reposition leaves to give Tertill a clear path. Raise leaves so Tertill can run under leaves. 1) Wait for sun or charge via USB 2) Press power button to enter patrol mode Eliminate ruts, holes, or rocks that can trap Tertill 1) Replace string 2) Use supplemental USB charging so robot runs longer Robot doesnt cover the whole garden Vegetation is too dense Robot doesnt start automatically 1) Extended cloudy period 2) Robot is in Hold mode Robot gets stuck Garden contains a terrain trap Robot patrols but weeds are growing 1) Whacker string too short 2) Garden is large Tertill Owners Manual 20 www.franklinrobotics.com Advanced Tertill Tertill seems simple enough--it moves about the garden and chops down weeds. But theres lots going on under the hood and theres additional complexity in the way Tertill interacts with the environment. This section is for those who are curious about such things. Operating modes The diagram shows a simplified version of Tertills operating modes and the events that trigger a switch from one mode to another. Blue-outlined modes show when a Bluetooth connection can be made. Tertill is always in one of four modes: Auto-charge, Patrol, Hold, or Hibernate. Auto-

charge and Patrol are autonomous modes. Tertill decides for itself when to switch from one to the other. As the names imply, Tertill charges its battery in Auto-charge mode and drives around searching for weeds in Patrol mode. When you press and hold the power button or invert Tertill it goes into Hold mode. Tertill will not leave Hold mode and begin patrolling until you press the power button. Dont forget to press the buttonTertill will wait indefinitely for this authorization to enter Patrol mode. Battery charge falls slowly over time (days) when no sunlight is available. At some point, to protect its battery, Tertill enters Hibernate mode. It can remain in this mode for months without damage. When you want Tertill to resume its duties, place it in bright Tertill Owners Manual 21 www.franklinrobotics.com sunlight for an hour or so (or charge the battery using USB) then press the power button to bring Tertill back to Hold mode. Programming paradigm Tertill follows a robot-programming paradigm known as behavior-based programming. Specialized software modules (behaviors) control Tertill in specific situations. Sensor readings and time cause Tertill to switch from one behavior to another. This architecture makes Tertill highly responsive to conditions it encounters in the world. Sensing Tertill senses the world in several ways. It uses capacitive sensors to detect plants, weeds, and conductive obstacles. It has wheel rotation sensors to detect and control the motion of its wheels. It uses accelerometers and gyros to, among other things, detect non-conductive obstacles and avoid dangerous slopes. The garden environment is a much more challenging realm than the floor of a living room (where robot vacuum cleaners have operated for years). The garden surface isnt flat, vegetation can build an inadvertent trap, the robot can accidentally dig a hole for itself, rocks can create a high-centering hazard, and sometime it rains. Tertill does very well amid this verdant chaos but it occasionally encounters a terrain feature that confounds it. So you may occasionally find Tertill stuck. The best solution is to eliminate or alter the feature that caused the trouble. If theres a rut or a depression, fill it. Remove troublesome rocks and block off entwining vegetation with a plant or row collar. From Tertills point of view, rain looks a lot like plants. When the sprinkler is going or rain is falling, a coat of water on Tertills chassis may make the robot think its surrounded by plants. If this happens it will spin in place a couple of times, looking for an escape path, and then stop (enter Auto-charge mode). After a while it will try again. As soon as its mostly dried off Tertill will patrol as usual. Sometimes Tertill may find its way into a position where it really is completely surrounded by plants. In this case you will have to intervene. Place the robot in a different spot where it has room to maneuver. Scrubbing weeds When weeds sprout from seeds they pass through the cotyledon or white thread stage. In this part of their life cycle they are quite vulnerable to disturbances in the soil. Thats one reason that Tertill has treads (or grousers) on its wheels. As it drives about, the grousers scrub the soil and can kill the emerging weeds. Tertill Owners Manual 22 www.franklinrobotics.com Some soil types, however, are more protective of early stage weeds than others. In sandy, loose soil Tertill is more effective at killing small weeds than in compacted or clay-rich soils. If you have the latter type of soil you can help Tertill by occasionally raking or otherwise loosening the soil surface. Big Gardens Tertill was designed with the typical size garden in mind. The median area of a US garden is about 100 square feet (9.3 square meters). If your garden is significantly larger than this and weeds seem to be gaining on Tertill, you may want to take some additional steps. Make sure that Tertill operates as efficiently as possible. Take extra precautions to remove rocks and smooth the surface. Use a fence that Tertill can detect (e.g. wood or wire). Increase the spacing between crop rows and individual plants (for next season). Give Tertill extra weeding time by occasionally charging its battery via USB. After charging in this way Tertill may run for about an hour. You can even use this method to enable Tertill to chop weeds at night. Supplemental charging enables Tertill to work much longer than when it relies on solar power alone. If weeds tend to be more of a problem in one part of the garden than another you can put up a temporary fence. Confine Tertill to the problem area until it has eliminated the weeds there. If all else fails, consider getting your Tertill a buddytwo Tertills do twice the work of one. Multiple Tertills can work together in the garden without interfering with each other. Tertill Owners Manual 23 www.franklinrobotics.com Cautions Do not disassemble Tertill. There are no user serviceable parts inside. If service is required contact Franklin Robotics. Do not immerse Tertill in water and do not spray with a high presser sprayer. Do not operate Tertill in the garden with the waterproof USB port cap removed. Do not expose Tertill to fire or flame. Do not operate Tertill in an explosive environment. Do not place anything on top of Tertill as it operates. Do not use trimmer string other than the string supplied or residential grade 0.050 string. Pick up Tertill only from the back using the molded-in handle. Picking Tertill up from the front may activate the weed whacker. Keep your eyes a safe distance from Tertills whacker string. The whacker can potentially fling small debris. Tertill is not a toy. Do not allow children to play with Tertill or to play unsupervised in a garden where Tertill is working.
