Obstacle Avoiding Robot

Abstract

The obstacle detection scheme would be based a sonar sensor, one for forward direction , a microcontroller would take input from the sensor and then compare the inputs to decide where the robot should turn. It would then give input to the two h-bridges which would in turn direct the motors to control the movement of the robot. Apart from that we will use a 5v battery to power the microcontroller and the motors. In robotics, obstacle avoidance is the task of satisfying some control objective subject to nonintersection or non-collision position constraints. Normally obstacle avoidance is considered to be distinct from path planning in that one is usually implemented as a reactive control law while the other involves the pre-computation of an obstacle-free path which a controller will then guide a robot along.
