Dear all, I'm trying to build a closed chain robot and control it over ros_control.

Since URDF does not allow for closed kinematic chains, I've implemented my robot model in SDF.

The robot has three linear actuators.

Then, I created a fake URDF just to load the ros_control controller.

The approach seems to work for both EffortJointInterface controllers and VelocityJointInterface controllers, but the robot does not move when commanded in position:

I check the feasibility of the solution before sending the commanded position.

Any idea on how to solve the issue?
