The invention relates in particular to generating and automatically controlling a force for moving a moveable element located in real time. The device includes means for generating a force of movement, said means being controllable so as to generate a force in a plurality of different directions. Said device also includes: means for receiving a radio signal; means for transmitting an electromagnetic signal, said electromagnetic signal being transmitted in response to an activation signal and allowing a moveable element comprising said device to be located in real time; and control means connected to said reception means and to said means for transmitting an electromagnetic signal. The control means are configured to control the means for generating at least one force of movement, in response to information for controlling a received electromagnetic signal, and for generating an activation signal, in response to synchronization information of a received radio signal.
