Abstract
A method and apparatus for controlling a telepresence robot.
Claims9
A method for calculating a remote vehicle path, comprising the steps of:
- moving a remote vehicle along a trajectory;
- accepting an instantaneous target destination as an input to a computational device;
- calculating a path to the instantaneous target destination, such that the path has a turn radius that varies based on the instantaneous target destination;
- and
- modifying a trajectory of the moving remote vehicle such that it substantially comports with the calculated path to the instantaneous target destination.

A method for compensating for a remote vehicle control latency, comprising the steps of
- capturing a video image from a remote mobile robot camera;
- associating a current robot position with the video image;
- transmitting the video image and the current robot position to a mobile robot control station;
- calculating a predicted robot position at the mobile robot control station;
- calculating a translation amount based on the current robot position and the predicted robot position;
- translating the video image by the calculated translation amount;
- and
- displaying the translated video image on display at the robot control station.

The method of step 5, further comprising the steps of calculating a zoom amount based on the current robot position and the predicted robot position, and zooming the video image by the calculated zoom amount.
The method of step 5, further comprising the steps of:
- transmitting the predicted robot position to a remote mobile robot and compensating for inaccuracies in a predicted trajectory of the robot by recalculating a movement path at the robot.
A method for enabling backwards motion of a remote vehicle, comprising the steps of:
- displaying a video image of a view taken by a remote mobile robotic camera on a video display;
- selecting a region of the video display beneath the video image;
- and
- generating a command to move to the selected region.
