Ning3 (2009) by Ng Beng Kiat, Ngee Ann Polytechnic, Singapore. Ning3 won the "Robotrace" Line Tracer competition at the 30th All Japan Micromouse Competition in 2009 with a time of 31.02 seconds.
"Ning3 is my first line tracer. It originally had 2 wheels. It was modified in 2010 to have 4 wheels." – Ng Beng Kiat.
The "Robotrace" Line Follower contest was first up at the 30th All Japan Micromouse Competition. "There were a few gasps as the track was revealed. It was huge! I don’t know how long it was but it took 20 pieces of MDF sheet, each about 1m x 1.5m to hold it. I would estimate the course at 50m in length. Styles of robot varied quite a lot. Historically, these were quite large with sensor arrays attached to the front wheels and Ackerman steering. This course was simply too tight for many robots of that style. The smallest radius turns left some of them simply unable to see the turn markers – particularly as they came out of the turn. The rules of this contest allow only three minutes per contestant to perform a discovery run and one or two speed runs. Many contestants used up a surprising amount of their precious time adjusting sensors. Some rendered themselves barely able to make a discovery run. Even the winning entry – Ning3 from Ng Beng Kiat – managed his three runs with only one second to spare." – Micromouse Online, All Japan Micromouse 2009 Monday.
