How to: move a simple box in the air

Hello all,

I would like to have a simple box moving in the air with a precise position/speed.

What I did so far is to create an SDF model with 3 prismatic joints fixed to the root. Then the joints are controlled by PID controllers (YARP's controlBoard). The PID-tuning was a bit complicated and it results that the speed and the position are not accurate enough for my purpose.

How would you get a "hard defined position / speed" controller working?

Is the box going to collide with other objects in simulation?

not at all, it will be a screen that displays images to the actual robot

In that case, the animation suggestion below is convenient, but it might be hard to specify a very precise trajectory. If you need precision, you could make the model static and call SetWorldPose on it.
