The task of this robot is to collect small metalic objects (such as batteries) which lie on the ground. The robot has to do so, while avoiding the collision with stationary objects and be able to navigate through complex enviroments. To search and collect the metalic objects, the robot is equiped with a small metal detecting circuit (based on induction). This offers a small rang of metal detection (aprox. 4 cm). The metal detector is placed on a long rod, which rotates 90 degrees. Therefore, the detector can locate metalic objects, anywhere in front of the robot. When a metalic object is detected, the rod's head (where the metal detector is placed) turns 180 degrees, and a big electromagnet now faces the metalic object. When the object is collected by the electromagnet, it is then released on a special platform which is deployed from the base of the robot. To avoid any collision with other objects (such as furniture), the robot uses an ultrasonic range detector (radar) as well as 2 side infrared range detectors. The radar, placed on top of the robot, searches the area infront of the moving robot for obstacles. If one is located within close proximity (30cm), the radar scans the area (rotates with the use of a motor) for any other possible paths which contain no obstacles within range. The 2 side IR range sensors make sure that if something misses the range of the radar, a side collision won't occur. The robot is controlled by two Basic Stamp 2 microcontrollers (one Basic ...
