US 7,970,492 B2 · Mobile robot control system

Abstract

In a mobile robot control system, it is configured to input at least one of the desired position and orientation of the robot at a time when the robot reaches the desired position by manipulation of the operator, to control the motion of the robot based on the inputted desired position and orientation, and to display a first image indicative of the inputted desired position and orientation by numeric values or language including at least the numeric values and a second image indicative of the inputted desired position and orientation by graphics on a display. With this, the operator can check the desired position and orientation of the robot with both of the numeric values and graphics. As a result, it becomes possible to prevent the operator from manipulating erroneously and operate the robot to be moved or turned as desired by the operator.

Dependent claims

A system for controlling motion of a mobile robot such that the robot moves to a desired position, comprising:

a. means provided to be manipulated by an operator for inputting at least one of the desired position and orientation of the robot at a time when the robot reaches the desired position;
b. means for displaying an image indicative of the inputted desired position and orientation on a display;
c. means for controlling the motion of the robot based on the inputted desired position and orientation;
d. means for setting an upper limit of a distance from a current position of the robot to the desired position;
and
e. means for invalidating the inputted desired position when the distance exceeds the upper limit;
and the means for displaying displays a first image indicative of the inputted desired position and orientation by numeric values or language including at least the numeric values and a second image indicative of the inputted desired position and orientation by graphics composed of arrows whose directions and lengths are changeable.
