Abstract: For training an object picking robot with real and simulated grasp performance data, grasp locations on an object are assigned based on object physical properties. A simulation experiment for robot grasping is performed using a first set of assigned locations. Based on simulation data from the simulation, a simulated object grasp quality of the robot is evaluated for each of the assigned locations. A first set of candidate grasp locations on the object is determined based on data representative of simulated grasp quality from the evaluation. Based on sensor data from an actual experiment for the robot grasping using each of the candidate grasp locations, an actual object grasp quality is evaluated for each of the candidate locations.

Abstract: A method and apparatus for automatic charging of electric vehicles in which a plug head of a charging unit is automatically received in a receiving compartment of a vehicle charger actuation device. A push wall of the vehicle charger actuation device is displaced into contact the plug head in a manner that facilitates rotation of the plug head into angular alignment with the plug head receptacle. The charging unit can align a position of the plug head with the plug head receptacle such that continued displacement of the push wall displaces the plug head to a position at which the plug head is electrically coupled to the plug head receptacle. After a charging event, the push wall moves away from the plug head receptacle and engages a pull rod that is coupled to a pin skirt such that the pin skirt is displaced in a direction that ejects the plug head from the plug head receptacle.
