KINGRIP
site navigationPresentation
The KINGRIP is a pair of instrumented handles specifically designed to instrument a KINARM End-Point lab. Each KINGRIP handle has a removable cover to be grasped in a power grip (with cover) and in a precision grip (without cover). Each handle is instrumented to measure the normal force (grip force, GF) and the horizontal tangential force (load force, LF) applied on each contact surface. The proximity sensor of the KINARM is supplemented by one finger proximity sensor beside each contact surface. The KINGRIP handles are connected to a dedicated force amplifier with analog outputs.
