This isn't really a robot but it's the best category I can think of.

This machine is controlled by a PicAxe Microcontroller. A servo (used for steering in R/C cars) is used to tilt the track for a ball to roll round. The degree of the tilt can be controlled by a potentiometer in manual mode or in automatic mode preset instructions on the microcontroller tell the servo how to move.

Very neatly made.
Perfect curves and excellent soldering. Well done.

EDIT:
How about a nice slow gentle servo movement so that it's not obvious how it works?

I've updated the code since the video so that on automatic mode loops are used for some routines. The loops also have the advantage of making it run quieter because the motor doesn't jump around. I'll get a new video up soon.

I should probably look into reducing the code size as I am right on the limit.


As I added to the original post here is a link with more information.

Thanks for telling me! I do subscribe to that site but it's buried at the bottom of my RSS page so I rarely visit. I didn't submit it to them so someone must have liked it. I did submit it to Makezine, they are a high volume site and the few things I've had published there got tons of views from them but so far they haven't used it.

No prob. It was nice to see a PICAXE on there. Hackaday has a rough crowd though. I think your project is neat.
