A method and apparatus for controlling an industrial robot relative to an intuitive motion coordinate system. The current 3D position of a touch-screen teach pendant relative to the robot is sensed, and an operator-centric frame of reference is developed relative to the robot-centric frame of reference. A simulacra of the robot is generated, oriented so as to correspond with an operator view of the robot from the current position of the controller, and displayed on the pendant. A motion-control construction, generated and displayed on the pendant, is adapted to receive jog commands from the operator indicative of a respective incremental movement of the simulacra in the operator-centric frame of reference. Each jog command is transformed from the operator-centric frame of reference to the robot-centric frame of reference, and the robot moved in accordance with the transformed jog command. Movement of the pendant relative to the robot is sensed and, in response, the displayed simulacra is reoriented to correspond to the new position of the pendant relative to the robot as viewed by the operator.

Intuitive motion coordinate system for controlling an industrial robot

A device including a housing configured to attach to a robot arm, and a multi-axis motion sensor provided within the housing. The multi-axis motion sensor is configured to detect movement of the housing, and is configured to communicate with a controller of the robot arm. The device further includes a user interface configured to operate in conjunction with the multi-axis motion sensor, and a connection port provided on the housing. The connection port is configured to connect to an external device.
