Evaluation of human physical burden on Simple Self-Transfer Aid Robotic System

We have developed a simple self-transfer aid robotic system and have conducted evaluation experiments. The users targeted are people with impaired walking ability who use a wheelchair, however are still able to walk to some extent. With the aid transfer, these users can maneuver themselves independently to and from apparatus, in this case, toilets. In practice, users lean their upper-bodies onto the saddle of a robotic arm, which lifts and transfers them to their destination. We have conducted the detail experiments on the human physical burden of the self-transfer aid robotic system, and have confirmed that the human physical burden was able to ease when using optimum conditions of the arm length and arm speed of the self-transfer aid robotic system.
