Employment of motion capture to measurement of motion parameters of the lower limb exoskeleton

Kuźmierowski T. , Ostaszewski M.

tom Vol. 17, no. 3

893-898

The article presents a software developed by the authors for data collection using the motion capture technique. Elements placement recording was based on color markers. The measured object was the lower limbs exoskeleton which has been constructed by the authors. The software contains an algorithm of marker location conversion onto angular displacements of each segment forming a rotational kinematic pair. Transducers mounted on the exoskeleton construction that measure direct joint angular displacement were used in order to verify data collected by the software.

This paper defines the design assumptions for the construction of an original demonstration of a CPM device, based on which a solid virtual model will be created in a CAD software environment. The overall dimensions and other input parameters for the design were determined for the entire patient population according to an anatomical atlas of human measures. The medical and physiotherapeutic community were also consulted with respect to the proposed engineering solutions. The virtual model of the CPM device that will be created will be used for computer simulations of changes in motion parameters as a function of time, accounting for loads and static states. The results obtained from computer simulation will be used to confirm the correctness of the design adopted assumptions and of the accepted structure of the CPM mechanism, and potentially to introduce necessary corrections. They will also provide a basis for the development of a control strategy for the laboratory prototype and for the selection of the strategy of the patient's rehabilitation in the future. This paper will be supplemented with identification of directions of further research.
