An Analytical Modelling of Demand for Driving Torque of a Wheelchair with Electromechanical Drive

This study aimed at analysing the influence of the position of the centre of gravity variability and the movement velocity on the demand for a torque and work time coverage of a wheelchair with an electromechanical drive. The variable parameter in the study was the configuration of the wheelchair, n...
