It's a great robot! His remote controller seems a bit cobbled together, but you can easily use a $50 RC controller with a $5 receiver and an Arduino to control whatever you want with 16 channels, it's amazing!

I'm fairly certain his robot was designed and built before Arduino's existed. The barrier to building robots and electronics has come way down in the past 15 years.

Funny you should mention it— I built a line-following system into the forklift, using an Arduino: I put a row of 16 downward pointing leds on the bottom of the chassis; the Arduino sequentially scanned all 16 leds. A photocell detected reflected light from the floor, and fed this into the Arduino’s analog input. In turn, this let the Arduino decide which side of the line it was on, and how much to turn to get back on track.

But odometry proved a bit more challenging, and it turned out to be more reliable (and fun) to simply move it using a RC controller.

Perhaps this is a small scale look into the future of the self driving car industry.
