Abstract:
1. A cooperative-control robot, comprising: a base component; a mobile platform arranged proximate said base component; a translation assembly operatively connected to said base component and said mobile platform and configured to move said mobile platform with translational degrees of freedom substantially without rotation with respect to said base component; a tool assembly connected to said mobile platform; and a control system configured to communicate with said translation assembly to control motion of said mobile platform in response to forces by a user applied to at least a portion of said cooperative-control robot, wherein said translation assembly comprises at least three independently operable actuator arms, each connected to a separate position of said mobile platform, wherein said translation assembly further comprises at least three linear tracks arranged such that each of said at least three independently operable actuator arms has an end that is constrained to move along a respective one of said at least three linear tracks, and wherein, in response to said forces by said user, said control system causes said mobile platform and said tool assembly to move in a smooth manner.
