CHASSIS DESIGN & MECHANICAL CONSIDERATIONS
SELECTING A CHASSIS
Size & Weight: Should accommodate motors, a battery, and your Arduino or driver board.
Mounting Points: Check that your motors can be screwed or snapped in securely.
Wheels: Choose wheel diameter and tread based on how fast or grippy you want the
movement.
WHEEL ATTACHMENT
Motor Shaft Compatibility: Use wheels or couplers that match your motor’s shaft type
(D-shaft, round, etc.).
