LOW COST DEVICE FOR THE LOCATION OF AUTONOMOUS ROBOTS.

摘要

Low cost device for locating autonomous robots. The present invention relates to a low cost device for measuring the position and orientation of mobile thefts indoors. The device consists of a transmitter located in a surrounding wall and a receiver in the upper part of the robot. The emitter is a laser pointer that acts as a rotating beacon and the receiver is a combination of photocells that form a cylinder. The position of the robot and its orientation is obtained by taking the times in which the laser light impacts each of the photocells. The device consists mainly of three distinct blocks: 1) Emitting subsystem that generates the laser light that moves in the horizontal plane. 2) A receiving subsystem. Which consists of a set of sensors grouped together forming a cylinder to cover all possible directions of impact of the laser light. The sensor set must be at the same height as the emitter in order for the laser light to hit the sensors. Inside the cylinder, formed by the sensors, is the electronics that identify the cells in which the laser affects as well as the time and duration of the incidence of the laser in each cell. 3) A laptop on the robot makes the final calculations and gives the location and orientation data.
