A new and light wheelchair-mounted robotic arm (WMRA-II) was designed and built to meet the needs of mobility-impaired persons with limitations of upper extremities, and to exceed the capabilities of current devices of this type. The structure of the new robotic arm utilizes carbon-fiber and polycarbonate tubes to reduce the arm weight. The mechanical design incorporates DC servo drive, with actuator...
This paper describes design of a reusable motor control peripheral for system on chip applications. It integrates previously carried out work on motor speed sensing, current monitoring and generation of power device triggering signals. The idea of creating a customized PMAC (permanent magnet AC ) motor control peripheral, which can connect to a standard chip wide bus is presented. Since a peripheral...
