Help with motors

Hi all

I’m building a skid rover and finally works, but testing the function I saw problems with motors

I’m using a piborg monster 12v 300rpm

But when The rover is on the carpet or a grass it seems the motors has not enough power to move the rover.

I was reviewing the curve from motor controller and is fully linear.

Any suggestion to buy the motors? The rover is aprox 10kg weight

Thanks all



Check some calculator online like :

thank you very much @khancyr

You will need a lot more torque than 1 kg-cm per motor for a 10kg skid steer rover. As you have discovered skid steer requires more torque than a typical ackerman steer vehicle due to wheel skid in turns. Something like this if ~300 RPM is the speed range you need.
