I am using velocity control, not position. So, Jacobian it is..

Well, my controller does not require the maximum current. The current sent to motors are pretty low. So, I guess it can't be enough torque, no?

The wheels are fine when they're not in contact with ground. (Much faster but fine) When contacted with ground; it can go sideways (two wheels go inward two go outward) but during the motion; it starts chattering which cause vibration.
