If yes, then you can start LUBA with the newest firmware now. If no, please contact us to solve the issue. 12 4.Charging Station &RTK Reference Station Installation Note:

1. Read and understand the safety chapter before you install the product. 2. Use original spare parts and installation material. General preparations 1. Water filled holes in the lawn can cause damage to the product. 2. Give an overview of your house, your lawn and include all obstacles. This makes it easier to examine where to put the charging station, the reference station, and setup the virtual boundaries. 3. Decide where to install the charging station, the RTK reference station, the point of interest, the transport paths and the virtual boundaries for the work areas and no go zones. 4. Fill in large holes in the lawn. 4.1 RTK Reference Station Installation Factors that affect the Signal and Positioning Accuracy:

The RTK system of LUBA uses full frequencies multiple satellite-based system, such as GPS, BeiDou, GLONASS, Galileo, which improves the positioning accuracy to approximately 2 cm. However, the accuracy crucially relies on the GNSS signal, which can be weakened by the following:

Factor 1: Blocking:

1. If there is anything on or surrounding the antenna of RTK reference station, charging station and/or the mower, the signal will be weakened or blocked. Solution: DO NOT install the changing station and GNSS antenna near the roof, wall,tree or anywhere that may block the signal. We recommend you to install the RTK Reference Station of LUBA in a opensky1 area or on the roof&wall2. Note:

1) The distance between RTK Reference Station and the wall&roof&tree should be ideally at least the same as the height of the wall&roof&tree,as shown below;

2) As shown below, to set the RTK reference station the wall/roof to avoid coverage. 13 2. If the transmission path from RTK Reference Station and LUBA is fully obstructed by large metal wall or concrete wall. LUBA could not the the data from RTK Reference station and could not get cm level accuracy. Solution:

1) Make sure there is a free transmission path from reference station to the charging stationFor the initialization, LUBA need to be set on the charging station and get data from both satellites and reference station) 2) If your lawn is with O-shape, U shape , or with separate lawns,we recommend you to set the RTK reference station on a higher place, like on the roof. If your lawn is with L-shape, you can set the reference station on the roof or on the point as shown below. 3) If your Lawn is with O-shape, U shape , or with separate lawns,we recommend you to also use the signal extension kit to enlarge your reference station signal cover area. 3 .If there is a high long wall & roof & very dense tree in/around the lawn, the satellite signal of LUBA can be poor in the covered area. We recommend you to avoid most of the covered area when setting the map. Although our integrated navigation system can continue doing the positioning for LUBA, however, the accuracy of positioning without RTK is not as good as with RTK and can be decrease fast when satellite signal long time not come back( like LUBA does not get out of the heavy coverage). Also our App will show the position reliability map when the map is set, we highly recommend you to adjust your boundary with the poor positioning parts, to decrease the poor parts less than 10%. Factor 2: Signal Interference:

The communication transmission power gets weakened with long distance.Please make sure that the distance between boundary of the map and the reference station is less than 80m. Signals from the satellite are transmitted to the antenna after being reflected by the glass wall, large area of water surface(lake/swimming pool) instead of directly from the air. This is called Multi-path Effect. Solution:Install the reference station away(at least 5m) from glass wall or lake to get rid of the Multi-

path Effect. 4.2 Find a Good Spot to install RTK Reference Station As shown above, the RTK Reference Station should be set in a place:

1. At least 5m away from large glass wall & lake/swimming pool;

2. With open-sky area, meaning there is no any coverage on the top with at least 90 degree zenith angle( means the distance between RTK reference station should at least be the same as the height ofthe obstacle itself,as shown below);

14 3. The RTK Reference station should be set straight. 4. If there are tall trees with large crown, and we set RTK reference station in the lawn as shown below. The distance between the reference station should be at least the same as the height of the tree to the edge of the crown. 15 5. For O-shape, U shape , or with multiple lawns, we recommend you to set the RTK reference station the roof or wallas shown below. Also notice that the RTK Reference Station should not be covered by the roof or the concrete wall of the building;

6. For L-shape and the lawns on one side,and some U shape lawns, you can both set the reference station in the lawn or on the roof&balcony. Please notice that the transmission path between working area and the reference station should not be fully obstructed. 4.3 Find a Good Place to set Charging Station Note 1. The charging plate of the charging station must not be bent. 2. Put the charging station on a level surface.The max. tilt distance of charging plate is 2cm;

3. Put the charging station (A) were the docking point (B) has open-sky view. This means that 90of the sky in all directions must be unblocked. The charging station docking point (B) is 2m. in front of the charging station. 16 4. Both charging station (A) and the docking point (B) can not be covered by roof/wall/tree or any non-

original mower house/garage 5. There should be(do not have any obstacle) between charging station (A) were the docking point (B). 6. Put the charging station near a power outlet. 7. Do not cut or extend the low-voltage cable. There is a risk of electrical shock. 8. Put the power supply in an area with a roof and protection from the sun and rain. Put the power supply in an area with good airflow. 4.4 The RTK base is installed on the charging station Over view of the installation when its completed Installation Kit 17 Charging station RTK base Power adaptor for charging station Extension wire for charging station(10meters) RTK wire (2.5 meters) RTK base mounting pole 18 Step1Go through the 2.5meters RTK wire from A to B and then connect it to C. Step2Insert and fix the RTK base mounting pole to the ground from hole A on charging station. Step3Screw the other part of RTK base mounting pole together Step4Fix the RTK base to the mounting pole. The RTK base can be locked on the pole by driving the plastic screw on the back. Users can fix the RTK base on the pole first before fixing the pole to the ground as well. 19 Step5: Then connect the wires for each part. Done! Check if the LED on the charging station is green. If it turns green, then right. If it turns red, please pull out the adapter and do the charge. Step6:Check the LED on the RTK reference station. It should be blue or green, if green, then the RTK reference station initialization is done, you can use your LUBA now. If blue, please wait for a wait the initialization of RTK reference station until the LED turns green(will take several minutes). 4.5 RTK base is installed separately from the charging station& on the roof/wall Over view of the installation when its completed:

1. For current version, only one task with one lawn is supported;

2. Remove debris, piles of leaves, toys, wires, stones and other obstacles. Make sure children and pets are on the lawn. 3. If there is a sudden interruption and failure, follow the instructions in the app to continue or restart. 4. Avoid to drive LUBA to the fully covered area,in such area, satellite signal can be not good enough for cm-level positioning;

5. We highly recommend you to leave 10-15cm distance if you drive LUBA along the edge of a wall / fence / obstacles

/ ditches;

Create a Task:

1. Check if the Positioning Status is OK, and LUBA status is Charing or Ready. Click the Create 2. Planning start, control LUBA to set the virtual boundary. When the LUBA is driven to the start point, or you click the button, the virtual boundary will be closed automatically. Then it will show the message: Finished Planning. LUBA status will turn to be Ready when its completed. 3. For the permanent obstacles or long-time exist things(like trees/ large rocks/ spray heads/ flower beds etc.) We recommend you to set no go zone of LUBA for these parts, for the protection of both LUBA and your property in the lawn. 4. Drive the LUBA to the area where youd like to set no-go-zones first, and then click barrier button to start drawing the virtual boundary for them. 26 27 7. Start Mowing Note:

1. Make sure the height of grass in your lawn is Max.10cm. If the grass height in your lawn is higher than 10cm, please cut the grass to less than 10cm first. 2. If the grass height is higher than 60mm, we recommend you to set the knife height higher than 40cm, please make sure that each time, only about 1/3 height of the grass is cut(e.g. if your original grass height is 60mm,set the knife height of LUBA 40 or 45mm; if your original grass height is 9-10mm,set the knife height of LUBA 60mm;) 3. If any unexpected issue occurs, press the STOP button and lock LUBA. The STOP button has the highest priority. 4. When LUBA meet obstacles higher than 10cm,the ultrasonic sensor will detect the obstacle, the speed of LUBA will slow down, and continue mowing forwards, until the bumper touch the obstacle and then do the avoidance. This can avoid the frequent trigger of the obstacle avoidance by high grass. 5. If the lift sensor is triggered, LUBA will stop, please press grass cutting button and then start button to unlock LUBA. 6. If a task is already set, LUBA is doing the task automatically, press Auto-return button and then start button to call back LUBA. 7. Please mow your task area no more frequent than once a day. Too frequent mowing may do harm to your lawn. 8. The estimated task time is not accurate in this version ,please just ignore that. How to start mowing:

The map is already set, now you can choose Start task, or set a task schedule for LUBA about the task with this area. If you choose Start task, please set the task parameters and make sure that your LUBA is in the task area. If youd like to set a task schedule, please click the schedule button and set the task parameters Set the key parameters of the task:

Knife height: from the ground to knife.( e.g. if your grass is 80mm high, you set knife height as 60mm, then20mm of the grass will be cut);

Route Mode: we currently support single grid and double grid mode. We recommend the double grid mode. Time: set the time when your LUBA begin to woek, the frequency should not be more than once a day. Response to rain: when rain, the rain sensor of LUBA will be triggered and go back to the charging station. And abandon the work this time, the next time of your schedule, LUBA will work as usual.( The logic of rain sensor is still optimizing);
