I am building a small indoor model, differential drive, two wheels and a caster. Very standard,
The base is made of 3/16 plywood. I want to mount the motor on the top surface of the base so it doesn’t take away from the ground clearance. The motor bracket I have is a simple L-piece with four holes to screw to the base and two holes to screw to the motor. The wheel I have right now is 6cm diameter.
With that combination I get almost no ground clearance.
My option is to get a much bigger wheel.
Are there other options? For example if the bracket had less (or no) clearance between the motor and the plywood, this would gain me maybe 1cm of clearance. But still not much.
Any other suggestions?
