This is my
first attempt to build a robot. I designed it to
participate in the Mini Sumo (500g) division
project, I designed a custom PCB using the ExpressPCB
Mini Board service. I used their software – below you
can download my Schematic and PCB files. $51 for 3
boards, you can't beat that!
His first taste of action will be at the Chibotica/iHobby Expo competition on October 24-25, 2009. I hope to post some videos of the carnage.
For the brains on this board, I'm using a
16F876A microprocessor. It's a great chip with 2 PWM
outputs, and a number of analog inputs so it was perfect
for this project.
I wrote the code in C, using the Hi-Tech
PICC Lite compiler.
To power this guy, I'm using a 25C 11.1v 1500mAh LiPo battery pack. I ordered it from Go_Market on eBay. Yeah, it's probably overkill but didn't want to risk running out of juice in the middle of a match.
The chassis is simply a cheap aluminum project enclosure that I picked up from Radio Shack. After much hammering, bending, drilling and cursing, I ended up with a housing for all my components.
