Robot Charlie

He uses an ATMEGA168 chip for brains
The stuff from Robot Shop are two HS-475HB servos for drive, two HS-311 servos for the head, Sharp IR range sensors, On Shine low cost radios, and the FT232RL breakout board made by SparkFun I used to bootload the AVR.

New robot work in progress

Same as Charlie except new chassis, ATMEGA644 brains and nRF24L01 radios made by SparkFun for RC when needed. This time I also got Maxbotics ultrasound ranger with a Sharp IR ranger, plus a wireless video camera. Oh, plus a EM-401A GPS receiver and Dimension Engineering accelerometers

The HS-475HB servos are torqy as hell, that robot can still do inclines no problem.

My early works

I bootload ATMEGA168s since it’s easier, all you really need is a FT232 chip to act as a serial port so you can program from a laptop with only USB ports. If I use any other AVR chips I use my USBTinyISP programmer.

That’s not a POB eye, it’s a AVRcam and it’s a pain in the butt to use. All it can do is find 8 different colour areas, but the image quality sucks so it’s pretty useless.
It was cool for a while, but for the same price you can get a wireless video camera and a USB video capture device, then run RoboRealm on a computer to do way more.

And yes, to cut costs I recycle a lot of parts from older projects.
