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.
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.
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.
Secure the board with additional M4 nuts.
Place the two DC-DC buck converters near the centre of the bottom plate, and position the 18650 battery cases on the left and right sides.
The left side of the power supply is designated for the PC. Solder the following connections:
Power Supply → Power Switch → INA226 → DC-DC Buck Converter → DC Power Jack / USB.
The right side of the power supply is for the motors. Solder the following connections:
Power Supply → INA226 → Relay Module → Emergency Stop Button → DC-DC Buck Converter → XT30 Connector, then connect to the boards.
Attach the batteries, power switch and emergency stop button to the bottom plate using adhesive or glue.
Place the camera at the front of the chassis and secure it using a 1/4-inch tripod screw.
