Title: Present position recognizing method for mobile robot
Inventor: ARAKAWA HIROAKI
IPC: B25J19/02
Filed: 1991-07-19
Abstract: PURPOSE:To accurately recognize the present position of a mobile robot by measuring the traveled distance of the robot and the distance from an optional wall surface and recognizing a point which is set on a circle drawn around the position of the robot set at the precedent sampling time point with the traveled distance of the robot defined as a radius and coincident with the distance from the wall surface as the present position of the robot. CONSTITUTION:The position of a mobile robot set at the precedent sampling time point is referred to as O in the plane coordinates showing the traveling locus of the robot. The x-coordinate position is decided by measuring the distance from the wall surface by an ultrasonic sensor. Furthermore it is considered that the robot has a linear movement within a single sampling period. Thus the actual present position C of the robot is equal to the value obtained by solving an equation of a circle having the radius DELTAL and the center coordinates O as long as the moved distance of the robot withing the sampling time is defined as DELTAL. In such a way, the position C of the robot is obtained and the robot is controlled so that it reaches a target point T in the shortest time.
