摘要

The invention relates to a method and a guidance, system for use of robot. The robot has movement means (1), for enabling movement of the robot on the ground in a desired direction, coupling and operating means (2) for carrying out desired functions of the robot, a data processing unit (3) provided with a user interface, for controlling the robot's functions by a user, and a guidance system (4), being in connection with the data processing unit, by means of which passage of the robot is being guided by analyzing its surroundings on sonar technology. In the controlling of independent passage of the robot by means of the data processing unit (3) through the guidance system (4) in order to follow passage of a target (K), such as the robot's user, moving particularly in external circumstances or spacious interiors, at least three parallel sounding sensors (4al, 4a2, 4a3) are being used on the front side of the robot by co-operation of detection areas (T) thereof, whereby a detection area of a sounding sensor (4a3) in the middle is essentially longer than the detection area of the sounding sensors (4al, 4a2) existing at the edges.
