This can be used to levitate as well as provide propulsion.

The hind legs were somewhat specialized in that they not only supported weight, but also provided propulsion.

This was for steering the vehicle, since the machine itself only provided propulsion.

His orchestra did not provide much propulsion or dramatic pointing.

This is done by an active torsion mechanism, which provides both lift and propulsion.

It provided propulsion, orientation control, communications, electrical power, but lacked long-term life support functions.

In the case of a rocket, for example, the reaction mass is the fuel shot backwards to provide propulsion.

And the thing's body wasn't moving properly: no undulations to provide propulsion.

The module also provides the station's power, propulsion, and life support systems.

The opposite foot makes contact with the floor or ground, providing propulsion.
