Mechanical Assembly
Motor Placement on Chassis
The chassis supports four motors positioned symmetrically as shown below.
Motor ID | Position | IN1 pin (forward PWM) | IN2 pin (backward PWM) |
|---|---|---|---|
M1 | Front-Left | CH8 | CH9 |
M2 | Rear-Left | CH10 | CH11 |
M3 | Rear-Right | CH14 | CH15 |
M4 | Front-Right | CH12 | CH13 |
Ensure that the motor shafts face outward and the gearboxes face inward.
Mounting Procedure
Assembling The Car
Connect the encoder cable connector to the designated connector at the rear of the motor until a click is felt, indicating a fully seated connection.
Verify that the connector is firmly attached and not loose.
Repeat this procedure for all four motors.
Assemble the components according to the steps demonstrated in the attached assembly video.
Attach the Arduino board to the car chassis using the designated screws.
Attach it according to the following images:
Connect the Motor Shield V5.3 to the Arduino Uno, and then connect the encoder cables and the power cables to the board according to the following image
Continue and connect the remaining parts of the car according to the following video:
RPLIDAR Connection
Secure the LiDAR sensor to the designated mounting bracket using M2.5×14 screws.
Place the EVKIT V2N in the designated holes on the bracket.
Then, attach the bracket to the vehicle chassis using spacers and fasten it with M3×14 screws, according to the position and orientation shown in the image.
Connect the RPLIDAR to the EVKIT using the designated USB cable.
Connect the Arduino Uno to the EVKIT using the designated cable.
Connect the camera to the EVKIT using a USB cable.
Connect the batteries to the EVKIT and to the Motor Shield V5.3.
Make sure not to connect the batteries to the Arduino Uno.
