My First Maze Robot - Minotaur
« on: February 21, 2009, 11:34:54 AM »
Just wanted to share a couple pics of my first maze robot, which just took 3rd place at a work competition  ;D





Powered by a PIC 18F2685, (2) 7.2 VDC gearmotors with encoders, 3 analog line sensors, 2 digital line sensors, a Sabertooth 2X25 drive (overkill, but that's what I had).
I chose to build it a bit large because the maze track was made from pieces of wood, and the track was big (about 50' x 20').

Is that an Olimex PIC development board I spy in there!? Great to see another PIC-user on this forum!

Nice robot BTW. Any chance of sharing the source code?

Thanks.
It was a maze race.  The best time from start to finish wins.  It was a looping maze, which made actually solving it very difficult.  I didn't have quite enough time, so it "solves" the maze by making random turns at intersections.  It worked good enough, though.

Here is the source code for PIC 18F2685.  It is written for the HITECH C Compiler.

which just took 3rd place at a work competition
3rd place?! SoR members are only allowed to come in 1st! ::)

So where is the video? And uh . . . how long did this robot take to 'solve' the maze? :P

And the maze was just lines on the wood, right?

I'll try to bring home 1st next year  :)   It's tough, though, when your competition is culled from about 1,000 engineers in our building.

It solved the maze in about 140 seconds.  I'll post the video when I get a moment.  The track boards had a black line on them to follow.
