Josh Conaughty is really another outstanding student. He built a robot called MECCA. It ran on a 12 volt and 5 volt system. MECCA is controlled with an 8085 microprocessor.
The sensor at the top of the robot send data to the 8085 microprocessor about its location. If it see something in its path the sensor will tell the robot to stop. Then the robot will turn 90 degrees to the right, check the sensor to see if there is anything in front of it. If there nothing in front it will preceding on the new path. If there is something in its path, it will turn right again.
This robot was featured on Channel 3. It was an A+ program they had in the newspaper and Channel 3 came in and took videos of the robot working. They put the camera on top of the robot and ran it around the track in the room.
