  • Inverse optimal control for human approach
    Patent number: 12145268
    Abstract: A controller for an inverse optimal control approach robot may control movement of a robot body toward a human target along a trajectory according to a cost function. The cost function may include many terms. A first term may be associated with a duration of the trajectory for the robot. A second term may be associated with a social force and a final distance between the robot and the human target. A third term may be associated with a lateral acceleration for the robot. A fourth term may be associated with an angular acceleration for the robot. A fifth term may be associated with a longitudinal acceleration for the robot. A sixth term may be associated with a reduction of centrifugal force applied to the robot body.
