Operating Instructions

Once assembled and integrated with a compatible controller (e.g., Arduino, Raspberry Pi) and motor driver, the MC100 chassis can be programmed for various robotic applications. The Mecanum wheels allow for unique movement capabilities.

Basic Movement Capabilities:

• Forward/Backward: All wheels rotate in the same direction.
• Turning (Rotation): Wheels on opposite sides rotate in opposite directions.
• Sideways (Strafe): Specific wheel combinations and directions allow the robot to move directly left or right without changing its orientation.
• Diagonal Movement: A combination of forward/backward and strafing movements.

For programming and control examples, refer to the resources available on the Gitnova blog, which provides illustrative controlling examples with different wireless control modes such as Bluetooth, WiFi, and PS2.

Maintenance

To ensure the longevity and optimal performance of your MC100 chassis, regular maintenance is recommended:

• Cleaning: Periodically clean the chassis and wheels to remove dust, dirt, and debris that may accumulate during operation. Use a soft, dry cloth.
• Wheel Inspection: Check the Mecanum wheels for any obstructions or damage to the rollers. Ensure they rotate freely.
• Motor Check: Listen for unusual noises from the motors during operation. Ensure they are securely mounted.
• Connections: Verify that all electrical connections (if applicable, after your own wiring) are secure and free from corrosion.
• Storage: Store the chassis in a dry, cool environment away from direct sunlight and extreme temperatures when not in use.

Troubleshooting

If you encounter issues with your MC100 chassis, consider the following common troubleshooting steps:

• No Movement:
  • Check power supply to the motors and controller.
  • Verify all motor and encoder wiring connections.
  • Ensure your control code is correctly uploaded and running on the development board.
  • Inspect motors for any physical damage or obstructions.
• Erratic Movement:
  • Check for loose wiring or faulty connections.
  • Review your control code for logical errors or incorrect motor commands.
  • Ensure Mecanum wheels are clean and rollers move freely.
• Assembly Issues:
  • Refer to the Installation Manual (PDF) for detailed assembly steps.
  • Ensure all screws are tightened appropriately, but do not overtighten.
