The top one is two motors. Each motor runs two wheels (in the same direction). And the next diagram is two motors running two wheels, and one dummy wheel not connected to any motor to support the car framework. Which one would perform better?
What are you trying to move?
If it’s low, the two wheels will be sufficient, but three wheels will give you better stability against tilting… with a cost of slightly added friction for the static wheel
A small car, to be specific, a micromouse. And will the 4 wheel design not work?
It depends on your code. The 3 wheel approach is easier to steer but may fail with heavy load.
The 4 wheel approach with all 4 wheels driven is hard to steer because each curve depends on friction and slip of the wheels. With only 2 driven wheels it performs a bit better but not much. At least you'll have to control all curves manually due to random slip.
The 4 wheel drive is actually effectively a 2 wheel drive, because 2 wheels are controlled by 1 motor. If i keep the center of mass on the back side, would the 3 wheel still fail?
I didn’t see a 4-wheel design ??
This is the type of 4 wheel drive I am talking about
2 wheels per motor.
