PASSIVELY SAFE HUMAN INTERATIVE ROBOT
Click on the pictures and you'll find links to some awesome video.
At Disney Research Pittsburgh, we developed this beautiful human like robot. The actuator is based on passive fluid transmission with pairs of rolling diaphragm cylinders. The sealed working fluid ensures input-output symmetry and complete backdrivability.
We designed and built two robot arms that are connected by tubes pumped full of either air or water. As the video shows, if you move one of the arms using your hands, the other arm repeats those same movements.
