Description

technical field [0001] The invention relates to a system for measuring motion parameters and mechanical impedance, in particular to a system and method for measuring motion characteristics and mechanical impedance of human upper limbs. Background technique [0002] The human upper limb is the most flexible and the largest movement system in the human movement system. It is a multi-degree-of-freedom mechanical movement system with many complex structural joints. Measuring the movement characteristics of human upper limbs can be used to evaluate the operating ability and flexibility of human upper limbs, understand the natural movement laws of human upper limbs, and play an important leading role in the development of anthropomorphic skills for robots in the future. The mechanical impedance characteristics of the upper limbs reflect the physiological characteristics of the upper limbs such as muscle contraction. Compared with foreign scholars, there are fewer domestic scholar...
