Torque Required For a Motor to Move an Object on Wheels?
I want to build a 4 wheel robot. the maximum weight of the robot is approximately 100 kg. and the radius of my wheel is 150 mm (outer dia 300 mm and inner dia 280 mm)** and the width of the wheel is 120mm. I want to use 4 motors in 4 wheel in order to run my robot. this robot will run on a very rough surface or the sand like surface. Can anyone pls tell me what is the required torque of every single motor? If I want to use 2 motor to run the robot then what will be the case? If anyone can suggest a formula for calculating the torque it will be helpful.
