Micro Mouse

Micromouse is an event where small robot mice solve a 16 × 16 maze. It began in the late 1970s, although there is some indication of events in 1950. Events are held worldwide and are most popular in the UK, U.S., Japan, Singapore, India, South Korea and becoming popular in subcontinent countries such as Sri Lanka.

The maze is made up of a 16 by 16 grid of cells, each 180 mm square with walls 50 mm high. The mice are completely autonomous robots that must find their way from a predetermined starting position to the central area of the maze unaided. The mouse will need to keep track of where it is, discover walls as it explores, map out the maze and detect when it has reached the goal. Having reached the goal, the mouse will typically perform additional searches of the maze until it has found an optimal route from the start to the centre. Once the optimal route has been found, the mouse will run that route in the shortest possible time.

Last year SLIIT organized a micro mouse maze solving competition. This was built by us to participate that competition… This was the smallest robot I have ever built.

 It uses 6 Ir LEDs and receivers to detect the walls around the robot. To make this small as possible we’ve built this on a single PCB without a chassis

Parts used.

The main processor board is an Arduino nano. 6 IR LEDs and receivers are used to detect walls. mpu 6050 gyro module was used as acceleration and turning angle sensor. motor driver was l293 h bridge driver.
