The 57-pound device is a robot that a human could wear over his or her body either to assist or inhibit movement in leg joints.
In the inhibit mode, the robotic device would be used as an in-space exercise machine to supply resistance against leg movement. The same technology could be used in reverse on the ground, potentially helping some individuals walk for the first time.
RPO anyone?
Sounds like it could be a good XIO type device for VR.
