How exactly did the Trail Tracker work?

(1/2) > >>


Little camera on the bottom, it would sweep back and forth looking for the line. It's one of the first projects you make with Lego Mindstorms. ;)

MartyS (Gromit):
I doubt it was a camera back in '78, unless it was a very expensive toy.  Probably just a photo-diode or 2 and a light source.

Can't find any info on the Kenner Trailtracker anywhere on the web, or anyone selling one, must not have been very popular.

Would be cool to find one somewhere, I want my 3.7 seconds of fun.

I could have sworn I saw a commercial for a modern toy doing basically the same thing.

It works on the power of cheesy music.
