Abstract
A force transducer for a robotic arm comprises a plurality of axially-contractible cells. Each cell includes first and second end pieces which are interconnected by a pair of flexible connecting members. The connecting members are disposed on opposite sides of a longitudinal axis. The connecting members are deflected inwardly towards the longitudinal axis by a pair of electromagnets to cause a change in length of the transducer. The transducers can be used to impart movement robotic devices.
