Newest Member of the Robot Collection

This little guy is about 45 mm square, and about 55 tall.  The software is still under development, but he scoots around - sort of avoiding light  - at this point.  The 8-pin chip is an ATTiny85.  I write code with the Arduino IDE and program it using my Arduino as an ISP.  After getting B.bro 1.0 to act like a Braitenberg vehicle I decided to see how cheap and small I could go.  With different motors I think I can get the size down to about 25 x 30 mm with a unit cost of about $4.00 in quantities of 50.  I want to build 50.
