Sony patents robot control that stops objects from slipping out of grasp
Sony has been granted a patent for a system that helps robots hold objects securely by detecting when an item starts to slip in their gripper. The system automatically adjusts the robot's arm and base movement to counteract the slip, ensuring the object remains stable.
In the filing’s own words
The present technology relates to an information processing apparatus, an information processing method, and a program that allow stable grasping of an object. An information processing apparatus according to the present technology includes a detection unit that detects a slip generated on an object grasped by a grasping part, and a coordinative control unit that controls, according to the slip of the object, movement of a whole body of a robot in coordination, the robot including the grasping part. The coordinative control unit controls movement of each of configurations that constitute the whole body of the robot, the configurations including at least a manipulator part to which the grasping part is attached, and a mobile mechanism of the robot. The present technology can be applied to a mobile manipulator that grasps an object.
What exactly they claim (claim 1)
1. An information processing apparatus comprising: circuitry configured to detect a slip generated on an object grasped by a robot hand of a robot; control, according to the slip of the object, movement of a whole body of the robot in coordination by controlling a mobile body of the robot that causes the whole body of the robot to travel to a different position; on a basis of a control target value indicating an amount of controlling movement of each of configurations that constitute the whole body of the robot, control movement of each of the configurations so as to cancel the slip of the object; and calculate the control target value on a basis of a weighting factor indicating a proportion of the control target value of each of the configurations that constitute the whole body of the robot.
