This project involves the advanced design and development of an intelligent goal-based obstacleavoiding robot. The autonomous robot in this project can locate a user command specifying a goal station on a track of stations while avoiding obstacles. The robot avoids collisions by altering its direction or course and then proceeding on a track or path. Based on the perception it has collected through the sensors, the robot decides which new path to take to avoid collisions and reach its goal. The robot is intelligent enough to follow tracks of black tape and stop when it reaches the goal. Its implementation employs an ultrasonic sensor to measure distances to obstacles, an IR (infrared) sensor to follow the laid-out tracks, and a Bluetooth module to allow it to receive commands from a user. It uses servo motors as actuators for the motion of its ultrasonic sensor and DC motor actuators for its wheels. The robot successfully followed and avoided obstacles on tracks in a layout that would allow it to reach shelves and pick and drop items in a warehouse.
