Design and Implementation of an ObstructionDetection Robot

[摘要] Obstruction detection robot always tries to avoid obstructions in front of it. It uses Atmega 16a. It has four i/o ports. It automatically sense at how much is the obstruction. According to the distance calculated it directs the actuators to move in appropriate direction. The robot continuously emits infrared rays. It reflect back when it strikes on obstruction. The reflected IR beam is received by the IR receiver. According to the intensity of IR received the distance is calculated. If this is above a threshold value, then microcontroller sense this and directs the motors accordingly. There by it avoids the obstruction in front of it. The circuit finds variety of applications in our day to day life. It varies from robotics to games. These types of robots are also used in defense systems to track and detect explosives and also to diffuse them.
