Abstract

The Home Lift, Position and Rehabilitation (HLPR) Chair has a unique design and novel capabilities when compared to conventional powered wheelchairs. In addition to mobility, it provides lift and can transfer patients. Even though medical devices are developing at a rapid pace today, an aspect that is often overlooked in these developments is adherence to 'rider safety standards'. The contributions of this paper are three-fold: (i) novel design of a lift and transfer system, (ii) experiments and results towards improved stability test designs that include HLPR-type devices to meet rider safety standards, (iii) autonomous navigation and control based on nonlinear system theory of dynamic feedback linearization. Stability experimental results show promise for multi-purpose patient mobility, lift and transfer devices like HLPR. A method for autonomous maneuvers was tested in simulation and experiments. We also expect the autonomous or semi-autonomous mobility mode of the vehicle to be useful for riders who have potential neural and cognitive impairments.
