Picture of Simple Bots: Buck

Just like a bull, a bronco, and a ninja, Buck has a lot of kick. With spring-loaded feet, this noisy little bot does a lot of stomping about. Everywhere Buck goes, commotion ensues. This keeps people on their toes, which is a good attribute for any bot to have.

I love your bots your truly the father of simple bots
You should try some Sugru or rubber at the bottom for slightly more grip...
Where can I get those white plastic spacers? Thanks.

I got it at Ace Hardware.
I've always been a fan of your pics. But I see a slight fault for the first time. Your 'Go get stuff' image is a bit blurry (easier to pick faults than to do better I guess :-). But still AMAZING photography...

This bot reminds me of bull riding. A cool mod will be to make a bull shaped body with a cowboy on it :D

you need to make one out of lead and turn it on when you leave for work in the morning.
