Electromechanical design of a body weight support system for a therapeutic robot for rodent studies

As part of an ongoing effort to better understand and treat locomotor disorders, an over-ground therapeutic robot prototype to study recovery of locomotion after spinal cord injury in rodents is under development. One key element of the therapeutic robot is a system to support the partial body weight of a freely-moving rodent. This paper discusses the design requirements, fabrication, modeling, calibration and preliminary analysis of a highly back-drivable bodyweight support system prototype. In addition, a closed loop feedback control system was designed, simulated, constructed and tested. Hardware limitations were identified, and alternative control techniques were explored.
