#### Steps:
1. **Throttle Input Handling: **
- The throttle and joystick signal would be fed into the central processing unit.

2. **Speed Calculation: **
- The rotational speed of the rear motors is set by the Ø 680mm wheels.
- The front motor's rotational speed is scaled according to its Ø 290mm wheel size (to match the same translational speed).

3. **Signal Distribution: **
- The processed signals for all three motors would then be distributed accordingly, ensuring synchronization and proper speed matching.

### Considerations:
- Ensure the motor controllers you select can handle real-time adjustments.
- If using a PLC or processing unit, it must have enough I/O ports to manage inputs from throttle and joystick and outputs to motor controllers.
