Abstract
A robotic system that includes a mobile robot and a remote input device. The input device may be a joystick that is used to move a camera and a mobile platform of the robot. The system may operate in a mode where the mobile platform moves in a camera reference coordinate system. The camera reference coordinate system is fixed to a viewing image provided by the camera so that movement of the robot corresponds to a direction viewed on a screen. This prevents disorientation during movement of the robot if the camera is panned across a viewing area.
Claims23
A mobile robot system that is controlled through an input device, comprising:
- a robot that has a camera with a camera reference coordinate system having at least a first axis fixed to said camera and a mobile platform with a platform reference coordinate system having at least a first axis fixed to said mobile platform;
- and,
- an input device that causes movement of both said camera and said mobile platfoiin within the camera reference coordinate system such that the first axes of the camera and platform reference coordinate systems become aligned from a state wherein the first axes of the camera and platform reference coordinate systems were not in alignment.
A mobile robot system that is controlled through an input device, comprising:
- a robot that has a camera with a camera reference coordinate system with at least a first axis fixed to said camera, and a mobile platform with a platform reference coordinate system with at least a first axis fixed to said mobile platform;
- and,
- input means for moving both said camera and said mobile platform within the camera reference coordinate system such that the first axes of the camera and platform reference coordinate systems become aligned from a state wherein the first axes of the camera and platform reference coordinate systems were not in alignment.
A method for controlling a robot, comprising:
- moving both a camera of a robot with a camera reference coordinate system with at least a first axis that is fixed to the camera and a mobile platform with a platform reference coordinate system with at least a first axis fixed to the mobile platform, such that the first axes of the camera and platform reference coordinate systems become aligned from a state wherein the first axes of the camera and platform reference coordinate systems were not in alignment.
