Hi I have this question, currently I am building a minisumo robot that works with four solarbotics high traction wheels (pololu.com/product/642), and four pololu HP micro-motors.
When I started I used four 1:150 motors, that were really strong, but their limitation was wheel traction as them started to run in the air when pushing too much.
So I decided to try four 1:50 motors, and the result is the same, the motors can't be stalled (what I think is a good protection) as the wheels tart to run in the air.
With four 1:30 motors together and even lower torque the same happens.
So, which robot has better total push? The one of biggest torque? or as the wheels traction is limited, they own the same maximum push?
thank you, I am a high school student and I don't handle that mechanic/physics concepts.
