Object Velocity in Robot Frame using FrameTransformer

Hello everyone,

I am working on a project where a robot interacts with an object. Now I want to get the velocity of the object in the robot’s base frame. I can get its position using FrameTransformer, but as far as I can tell, FrameTransformer does not support the same functionality for velocity. Is the simplest way now to transform the velocity in the robot frame by hand, or is there a similar feature in IsaacLab?

Thanks in advance!
