Overview The goal of this project is to The goal of this project is to design a self- contained, electrically powered vehicle called a Micromouse design a self- contained, electrically powered vehicle called a Micromouse integrate a camera onto the Micromouse integrate a camera onto the Micromouse And to program the Micromouse to avoid obstacles And to program the Micromouse to avoid obstacles

Original Idea The mouse find its way through a maze and back, to the starting point within a specific time frame. The mouse find its way through a maze and back, to the starting point within a specific time frame. Turn in a grid space of the maze Turn in a grid space of the maze Must be able to turn left and right periodically Must be able to turn left and right periodically

Mouse Design Features A HexAvoider is a programmable mobile robot designed to move independently. A HexAvoider is a programmable mobile robot designed to move independently. It uses infrared emitters and receivers to "sense" its environment. It uses infrared emitters and receivers to "sense" its environment. The two antennas are used to sense obstacles. The two antennas are used to sense obstacles. The HexAvoider is programmed using C language. The HexAvoider is programmed using C language.

Mouse Design Features It is programmed on a PC and downloaded onto the chip using FLASH memory. It is programmed on a PC and downloaded onto the chip using FLASH memory. There is an option of including a RF module in the HexAvoider's construction. There is an option of including a RF module in the HexAvoider's construction. With this, the operator can directly control HexAvoider's movements from his PC. With this, the operator can directly control HexAvoider's movements from his PC.
