This is my first robot project. It's a 115cm tall creature powered by an Atom motherboard and a Delphi program under windows. It's remote controlled only by now (trough TCP) I plan to develop automations as soon as I learn how.

Nice robot!

where did you get the motors for the wheels from?

Thank you for your comments. The motors are a pair of argentinian made planetary gear motors very similar to these http://www.robotshop.ca/rbban30-banebots-planetary-gearmotor.html. I have to use them at ~35% of power for man walking speed and at that voltage the DC motors are weak. I recommend motors with a larger reduction.

What hapenned to K.I.S.S.?

You must have some sort of mechanical/electronics background to start off with something this big!


Anyhow, nice robot! I'll be checking for updates.

Well, I'm a very experienced software developer, I know a little bit of electronics and PIC programming and nothing about mechanics. But I'm unconscious enough to start a project of this size and learn on the way. Thank you for your comments, I'll be uploading some videos shortly.
That things awesome. I like the idea of using the atom.

I´m using the intel D945GCLF Atom motherboard which consumes about 80W. Its not bad but there is a better one (less power, same processor) look at http://us.kontron.com/products/boards+and+mezzanines/embedded+motherboards/miniitx+motherboards/ktus15mitx++16+plus.html


What does it DO?

I'm bustin' to see this video!

The strength of the arm has two key points:
1) Power: The robot carries a 45Ah (13Kg!) battery.
2) Money: Ultra high torque servos (24Kg-cm) and a gear box for the shoulder (5:1).
The use of a gear drive pan system (http://www.robotshop.ca/Servocity-SPG800-Gearbox-5m.html) for the shoulder was the best idea I had since my divorce. Not only gives strength to the arm, it also avoids the horrible servo vibration. The tradeoff is speed, of course, but if you don't plan to use it for perverted things, its ok.
