No, my gearmotors do not have any encoders, and yes, I do full PWM on them to control the speed.

End to end length of the motors and wheels is just under 4"...

Nothing. You really don't need it on a mini-sumo ring...

Sweet Looking robot. I can't wait to go up against it some time.

You going to bring it to San Francisco next June?

So, the 2009 Canadian National Robot Games are almost upon us (2 weeks from today, in fact). I decided to do a final push and finish this robot...

Its almost done - all that is left is molding the right tire, doing the front scoop, painting, and some software work.

Yes, the lid (and a few other pieces) are printed. Yes, I have a 3D printer now (Dimension uPrint).

Nice job Jon!

It must be a real treat to be able to fab parts like that! Not your usual hobbyist tool.

I see that it is a step between Seeker II and your Fast Fast Fast, robomaniac :)
