Patent Images
1. A system for preventing a collision of a remote-controlled mobile robot, comprising:
- a mobile robot transmitting image data taken by a camera mounted on the mobile robot and moving in accordance with received control data; and
a control appliance receiving and analyzing the image data, displaying the analyzed result on a screen, and transmitting the control data to the mobile robot,wherein an image of an obstacle that may collide with the mobile robot is color-mapped on the screen and an alarm signal causing the control appliance to emit an alarm is generated before the mobile robot collides against the obstacle, andwherein a collision expecting region color-mapped on the screen is adjusted to different colors according to a time of contact (TOC) of the mobile robot with respect to the obstacle positioned in the heading direction of the mobile robot.

3. An apparatus for preventing a collision of a remote-controlled mobile robot, comprising:
-
an image processing unit storing and comparing images of a heading direction of the mobile robot; an obstacle detecting unit detecting an obstacle positioned in the heading direction of the mobile robot to generate collision expecting information, calculating a time of contact (TOC) of the mobile robot with respect to the obstacle positioned in the heading direction of the mobile robot and calculating a collision expecting region where the mobile robot is likely to collide against the obstacle positioned based on the TOC; and a color-mapping unit generating color information to be mapped on the collision expecting region of the obstacle based on the collision expecting information, wherein the color-mapping unit adjusts a tone of color to be mapped on the collision expecting region in accordance with the TOC value. - View Dependent Claims (4, 5, 6, 7, 8, 9)
