Adding wheel diameter(diff_drive_controller) for a stl file added in urdf
I created a 4 wheel bot and i want it to move with the help of diff_drive_controller by giving parameters like all 4 wheel joints, wheel separation,wheel diameter and so on... the thing is my wheel is not created by a shapes, instead i added a stl file for left and right wheel. so, i have to give the wheel diameter to make it move, how can i give the diameter of a stl file which i don't know?
