title: Development of a powered mobile module for the ArmAssist home-based telerehabilitation platform.
abstract: The ArmAssist, developed by Tecnalia, is a system for at-home telerehabilitation of post-stroke arm impairments. It consists of a wireless mobile base module, a global position and orientation detection mat, a PC with display monitor, and a tele-rehabilitation software platform. This paper presents the recent development results on the mobile module augmenting its functionality by adding actuation components. Three DC servo motors were employed to drive the mobile module and a position control algorithm based on the kinematic model and velocity mode control was implemented such that the module tracks a path defined in the training software. Pilot tests of the powered mobile module were performed in experiments with different load conditions and two unimpaired subjects. Both test results show that the module is able to follow the predefined path within an acceptable error range for reach movement training. Further study and testing of the system in realistic conditions following stroke will be a future topic of research.
