Springston School Robotics

This term a group of students have been learning about line following with lego mindstorm NXT. me and the rest of my group have cracked how to follow the big green blob a the end but now we need to use the ultrasonic senser on the robot to detect a can in the blob we have been working on it at the moment it is quit hard but we have just started using it. Because what is the point if you can't get there in the first place but I have been haveing a lot of fun so far
