2017-09-15 06:30:33 -0600 marked best answer Changing velocity of a fixed object

I have a robot hand model with fingers that are torque controlled. The hand floats and has the task of grasping objects. So far the hand was first fixed to the world (with a revolute joint). Now I would like to add more degrees of freedom in order to allow for the hand to move freely by being able to set the velocities of the base.

The problem is that when I disable the revolute joint to be able to do this, the counter torques from the fingers make the whole model move. What I would like to have is to be able to move the hand around, but to make it act as it is fixed, i.e. to prevent the effects of counter torques to influence it (e.g. just be able to change the linear velocity of the base of the hand, but ignore all the forces acting on it). Is there a way to do that?

Is there a benefit to using a model plugin to change the state of a model, if a world plugin that can do that already exists? Or let's say I have 10 models that I want to manipulate at the same time? Or more general, benefit of using "lower level" plugins, when "higher level" ones exist.
