Abstract

A power-assist robot - Portable Physiotherapy Limbs Rehabilitation Robot (PPLRR) is developed to provide physiotherapy treatment for people with limbs disabilities. A huge number of disabled people are unable to receive physiotherapy treatment due to barriers such as physical disability, insufficient physiotherapist and facility, and difficulty in transportation. Most physiotherapy facility available in the market is too bulky and expensive which is not suitable for home use either or equipment unable to control range of motion with simple function. The invention of a home-based physiotherapy robot could increase chances of physiotherapy for disabled people. This study will focus on the development of mechanical structure of PPLRR which includes design and construct the overall robot structure which is suitable for home use. To control and enhance the range of motion exercise, linear slider paddle is designed and developed which is able to move linearly during cyclic motion. Electrical connection through rotating assembly is required for connecting sensors and components on linear slider paddle. The main cyclic motion for cycling patient‟s limbs is driven by a power transmission system which converts electric energy to mechanical motion. All the structure design is design with computer aided drawing (CAD) software after doing research and study in dynamics and mechanism. At the end of this project, a robot structure that suit disabled people‟s needs with linear slider paddle will be integrate with integration control and control manipulation for a complete robot to be tested on healthy person for adjustment and calibration before proceed to test on minor disabled patient. PPLRR can benefit many disabled people in the way of considering their needs and convenience, creating more chances of physiotherapy and at the end bringing greater hope of rehabilitation.
