Abstract

Systems, devices, and methods for time calibration. The method can include, in responses to receiving sensing data which indicates a deviation of a tool from an object to be operated by a robot with the tool, triggering the robot to perform a plurality of transformations. Each transformation causing the tool to contact the object at a reference position; determining joint positions of a joint of the robot holding the tool or the object after the plurality of transformations; and determining a position relationship between the tool and the robot at least partially based on the joint positions and the reference position.
