- Page 12 If you have a network RTK service account based on Ntrip, you can use the network RTK positioning solution without deploying an RTK antenna. Deploy RTK antennas In order to optimize the performance of the RTK system, the RTK antenna must be located in an open area to receive satellite signals.
- Page 13 Mark the installation position of the curved mounting rod on the wall. The mounting rod must be positioned vertically upwards.
- Page 14 Choose the appropriate screws according to the wall material and drill holes at the marked positions. For wooden walls: Use M6 screws and screwdrivers. For concrete walls: Use M8 expansion bolts and power tools (bring your own).
- Page 15 Install a direct hanging pole, RF antenna, and power cord (5m) on the RTK base station.
- Page 16 Securely fasten the two mounting rods.
- Page 17 Insert the DC to USB-C cable, adapter, and power adapter plug into the power outlet to activate the RTK base station. Deploy lawn mowers and charging stations Select a flat and level place to place the charging station. Ensure there is a clear, unobstructed horizontal area extending at least 2 meters in front of the station, devoid of hills, slopes, indentations, potholes, or obstacles.
- Page 18 Fix the charging station and garage to the ground with bolts.
- Page 19 Connect the power adapter, 10-meter extension cord, and power cord, and plug them into the power outlet.
- Page 20 Docking the robotic lawn mower After the deployment of the charging station and RTK antenna is completed, take out the robotic lawn mower and dock it with the charging station as follows: • Press the button on the charging station to ensure the indicator light turns green and blinks rapidly, indicating it has entered direct charging mode.

Waiting for base station functionality deployment to complete. Map management (Map management interface diagram and illustration to add) - Page 29 5.6.1 Build maps Notes before mapping Before creating a map, there are some points that need to be aware of: • Clean up debris, piles of fallen leaves, toys, wires, stones, and other obstacles on the lawn before creating a map. Make sure there are no children or animals on the lawn.
- Page 30 If the charging station location has not been marked, a prompt indicating no charging station will appear, asking if you wish to deploy. Click Deploy, and the app will initiate Bluetooth connection to the robotic lawn mower. After the app successfully connects to the robotic lawn mower via Bluetooth, read and confirm the requirements for charging station deployment.
- Page 31 The robotic lawn mower will autonomously leave the station. Once the robotic lawn mower stops, you can establish the passage via the app. The passage refers to the path the robotic lawn mower takes from the charging station to the working area. This path will be followed during actual operation to ensure it is a drivable path.
- Page 32 Click Start to use the joystick to remotely control the robotic lawn mower to the edge of the intended working area. Click Next to save the passage and proceed to establish the mowing area. After the passage is saved, the mowing area can be established through the app. Click the Start button, then use the joystick to remotely control the robotic lawn mower along the desired lawn edge to draw your lawn boundary.
- Page 33 Solid lines indicate the boundaries you have drawn, while dashed lines will help guide you back to the starting point. The mowing area will not be created until you control the robotic lawn mower back to the starting point and click Finish. If needed, click the Erase icon, and the robotic lawn mower will retreat along the drawn path to erase the boundaries of the retraced mowing area.
- Page 34 Control the robotic lawn mower to return to the starting point and then click the Finish button to save the working area. Name the work zone. Select the default mowing configurations for this area, including blade speed, travel speed, grass height, and path planning settings. Complete the mapping process for the mowing area.
