Abstract
A force/torque sensor device for a force/torque sensor means for a robotic entity, in particular a robot arm or a robot joint, includes two coaxially arranged flanges connected to each other via a plurality of mechanical transmission structures of the sensor device, wherein in each transmission structure a single deformable radial-beam firmly connects the inner flange to the outer flange. The radial-beam of each transmission structure is firmly connected to a decoupling-beam of the inner flange, wherein a radially outer circumferential portion of the inner flange constitutes this inner decoupling-beam in the inner flange.
