floating base about rbdyn HOT 4 CLOSED

Hello,

I am not sure to understand your question. However, the Inverse Dynamics algorithm only computes the inertia matrix and coriolis vector, then solves for the torque. If you want the torque applied on the floating base to be zero, you need to add constraints and solve yourself or use the Tasks library.

Note that if your forces and accelerations are well defined (e.g. obtained from motion capture), you should automatically get zero torque on the floating base.

@haudren ,hello.
I want to use RBDyn to let my humanoid robot stand in vrep simulator.In vrep i could get the ground force,and floating base position and orientation,and joint position.These value is fine.
Could you give me some advice to let my humanoid robot stand in simulation.What feedback controller need?
I use RBDyn controll Ur10 in Vrep very well through M(q)ddq+C(q)=t feedback controller.But it seem not work in floating base humanoid robot.
Would i realization it through use Tasks library?

I am sorry, I am not sure I understand you properly, and without knowing what your exact controller is, I can't help you. The Tasks library is designed for tasks-based control of all robots, but especially humanoids in multi-contact.

Thanks.I would learn the tasks library.
