Assembling the Bottom Plate
Motors
Insert the screws into the motor brackets and motors, then tighten them with a screwdriver. The motor shafts may face either upwards (top left of image) or downwards (right of image). This only affects the overall height of the robot. Repeat the process for the remaining motors, ensuring all shafts face the same direction.
Install the wheels onto the motors and tighten them using a hex key.
For a typical Mecanum wheel installation, the wheels should form an X pattern when viewed from above. Number all motors according to the reference image. The mounting hole for the camera indicates the forward direction.
Secure the motors using the holes highlighted in green.
Insert M4 × 12 mm screws from the top of the bottom plate into the bracket holes. Secure the motors using M4 nuts on the opposite side.
Repeat for all motors and verify that the installation is correct. It is recommended to label the motors with numbers on both the motors and the bottom plate.
Incorrect installation may cause the robot to behave abnormally.
Controller Board
Insert M4 screws through the controller board and secure them with M4 nuts on the opposite side, creating a standoff-like spacing.
Install the controller board onto the chassis, ensuring the PH2.0 connector faces the front of the chassis.
The scrws should be inserted through the holes highlighted in green.
Secure the board with additional M4 nuts.
Motors Controller Board Connections
Connect the PH2.0 connectors from the controller board to the motors according to the numbering. For example, MJ1 on the controller board should be connected to Motor 1 / Wheel 1.
Power Supply
Motors Circuit
Connect the components according to the following image.
For +J3 and +ESTOP, connect them to the PH2.0 connector.
The “+” symbol indicates the positive side, and the number indicates the negative pin.
Logic Circuit
Connect the components according to the following image.
For +J2, connect them to the PH2.0 connector.
The “+” symbol indicates the positive side, and the number indicates the negative pin.
Use the USB or DC jack to power the onboard computer.
