METHOD FOR DRAWING A MAP BY ULTRASONIC SENSOR AND MOBILE ROBOT USING THE SAME

摘要

A method for drawing a map using an ultrasonic sensor and a mobile robot using the same are provided to minimize the composition error of the lattice map by rapidly recognizing the fixation obstacle. A method for drawing a map using an ultrasonic sensor comprises an input process(S10), a mapping process(S11), a set up process(S12) and an renewal process(S13). The input process is performed to input the structure chart showing the obstacle. The mapping process is performed to map the lattice map and the structure chart. The set up process is performed to set the increment value to the lattices of the lattice map. The renewal process renews the lattice map by applying the increment value to the lattice corresponding to the obstacle.
