Robot and method of controlling the same
First Claim
1. A method of controlling a robot that operates while observing a surrounding environment, the method comprising:
- obtaining environmental information on the environment around the robot to dictate observed and unobserved regions, wherein the unobserved region is a region in which environmental information has not been obtained by the environmental information obtaining sensor;
determining as to whether the robot is operating in the observed or the unobserved region; and
reducing a speed at which the robot moves when it is determined that the robot is operating in the unobserved region,wherein the robot is operated in a free region when operating within the observed region and it has been determined that an obstacle is not present based on the environmental information,wherein the robot is operated in a prohibited region when operating within the observed region and it has been determined that an obstacle is present based on the environmental information,wherein when the robot is operated in the prohibited region, reducing the speed at which the robot moves, so that the speed at which the robot moves will be lower than the speed at which the robot moves when the robot is operated in the unobserved region.

Abstract
An object of the present invention is to provide a robot that can improve safety even when the robot is operated in an unobserved region and a method of controlling the robot. The robot according to the present invention operates while observing a surrounding environment. The robot includes environmental information obtaining means for obtaining environmental information on the environment around the robot and control means for reducing a driving force of the robot when the robot is operated in the unobserved region, in which region the environmental information thereof has not been obtained by the environmental information obtaining means.

2. A robot operating while observing a surrounding environment comprising:
-
an environmental information obtaining sensor configured to obtain environmental information on the environment around the robot to dictate observed and unobserved regions, wherein the unobserved region is a region in which environmental information has not been obtained by the environmental information obtaining sensor; and a controller configured to reduce a speed at which the robot moves when the robot is operated within the unobserved region, wherein the robot is operated in a free region when operating within the observed region and it has been determined that an obstacle is not present based on the environmental information, wherein the robot is operated in a prohibited region when operating within the observed region and it has been determined that an obstacle is present based on the environmental information, wherein when the robot is operated in the prohibited region, the controller reduces the speed at which the robot moves, so that the speed at which the robot moves will be lower than the speed at which the robot moves when the robot is operated in the unobserved region. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9)
