Toyota Motor Corporation has developed a human support robot (HSR) prototype to assist independent home living for persons with limited arm or leg mobility. Aiming to improve quality of life, Toyota has developed the HSR prototype in cooperation with the Japan Service Dog Association to identify the needs and desires of individuals with limited limb mobility, and developed functions focused around picking up dropped objects, retrieving items, and communicating with family members and caregivers. In 2011, TMC conducted in-home trials using the robot with individuals with limb disabilities in cooperation with the Foundation for Yokohama Rehabilitation Service and incorporated user feedback into development.
