Maze Solving Robot

This robot was made for the Search and Rescue challange by Ro-Bot-X.

It is a simple wall follower that uses an ultrasonic sensor for decting the wall and a SHARP IR sensor for sharp left turns. For picking up the soft toy bear, in my case a dog, the robot has a magnet on the side. So sometime on its journey the magnet will touch the bear and grab it. It grabs it because there is a small magnet taped to the waist of the dog. I would have used velcro but I couldn't get some in time for the deadline.

My maze is just some cardboard boxes (tissue, shoe, ect) that I had lying round. I know its not very big or complex, but its all I could do from what I had in the time I had.

In case your wondering the voices in the video are my brother and father arguing whether my brothers icecream cone has glue on it???
