Micromouse

Labirynt micromouse

Micromouse - a kind of robot occupation in which the 'mouse' robot has to overcome a labyrinth of flat surfaces and single-handed walls.

The origins of the micromouse dates back to the late 1970s.

The competitions are held all over the world, but are most popular in the United Kingdom, the United States, Japan, Singapore, India and South Korea.

The classic labyrinth is arranged in a square formed by connecting 16 walls on all its sides, each of which is 180 mm long and 50 mm high. Mice are completely autonomous robots that have the task of finding a path from a predetermined initial position to a central, unarmed part of the maze. Robots need to remember the path they moved, detect the walls while solving, draw a labyrinth, and figure out when they reached their destination. Since its completion, they make additional labyrinth searches until they find the optimal path from the starting position to the center. Since the optimal path is found, the mice follow this path in the shortest possible time.

Robo-mouse can move more than three meters per second, depending on the designed labyrinth. It uses different search algorithms.

Common algorithms use variations:

Among the various algorithms for traversing graphs and trees.

Newer micromouse versions called Half Size Micromouse were introduced at the 30th All Japan Micromouse Competition in 2009. Instead of a 16x16 maze, the new competition uses a 32x32 maze but the same square surface. Dimensions of chambers and walls have been reduced, providing new entertainment.

Kato-san, Ng Beng Kiat and Nakashima-san are some of the best robo-mice makers.

The current world record for robo-mice is about four seconds. It was set up by Kato-san.
