Hey thanks for ur help. I too dont know whether tanks use differential drive or steering. But if a tank has 8 wheels how can we use a differential drive? I mean which wheels use the drive and which are the followers ?
Also another problem is that I made a small model for the tank for which i have set the "mass" parameter as 47 tons. When I start the simulator the robot fall off through the ground. If I reduce the mass to 40 then it becomes stable. Why is it ? Can we solve it ?
