MODELING OF CONTROLLED OBJECT
A control system includes circuitry configured to: generate, based on a command profile representing a temporal change of a command for driving a controlled object and a response profile representing a temporal change of a state of the controlled object responding to the command profile, a first model representing at least a part of a relation between the command and the state of the controlled object; generate, based on the command profile, the response profile, and the first model, a second model representing another part of the relation that is not represented by the first model; generate, based on the first model and the second model, one or more control parameters representing a relation between a control reference and the command for causing the controlled object to follow the control reference; and control the controlled object to cause the state of the controlled object to follow the control reference based at least in part on the control reference and the one or more control parameters.
METHOD AND SETUP FOR FENCELESS ROBOTICS
A fenceless system and method for automatically moving one or more items between a structure at a source location and a destination using a robot is provided. The system comprises a robot having an end effector to selectively grasp an item. A trajectory planning controller directs the robot to move the item between a source location and a destination. A touch sensor detects a contact between an external object and a surface of the robot or a surface surrounding the end effector; and a proximity sensor detects a person in proximity to the robot. A vision sensor detects a location and orientation of items to be moved. The robot moves in proximity to a person without a safety fence preventing the person from contacting the robot. The system adjusts a speed of the robot in response to detecting a person in one of a plurality of zones around the robot.
