Abstract:
1. A multi-degree of freedom transducer for convening manually applied forces and torques into electrical signals and configured to be fixed to a base object, the transducer comprising: a handle bar configured to be gripped by an operator comprising two ends and a first longitudinal direction; a supporting assembly suitable for fixing the two ends of the handle bar to the base object, the supporting assembly comprising a frame structure at each of the ends of the handle bar, each of the frame structures comprises at least two measuring beams, at least one of the measuring beams having a second longitudinal direction and at least one other of the measuring beams having a third longitudinal direction, wherein the first, second and third longitudinal directions are different from each other, each of the at least two measuring beams comprises two strain gauges configured to sense strain in the third longitudinal direction and arranged on two different, non-parallel side surfaces of each of the at least two measuring beams, wherein the transducer is configured to convert manually applied forces in three degrees of freedom along each of the first, second, and third longitudinal directions and torques in three degrees of freedom into electrical signals corresponding to movements of the operator's wrist and/or hand.
