Scuff Planning Notes
The idea for Scuff began with a piece of scrap. About a year back, Steve was cutting out Sintra circles to test his CNC. He tossed a couple to us during a BuildFest. We traded with someone so as to have two of the same color. Having just finished the round Abcore Turbot, I held up the circles and jokingly said that we should make a Turbot out of them.
Everyone laughed and that, for some reason, made me want to actually go thru with it. It took us about a year to get it all done. I kept redesigning the body. Frankly, only the Micro Robot Contest prompted us to finished Scuff.
Pin-out
Our robots are built to be disassembled and reassembled. To this end, with Scuff we are using an eight-pin female port for connecting both motors and the top solar cell and photodiode. This is the planned pin-out:

4) Motor 2 in 1, Pin 14 and 15
5) Photodiode Up Cathode, to Vcc
6) Photodiode Up Anode, to Photodiode Down Cathode
7) Solar Cell 1 V+, to Solar Cell 2 Gnd
8) Solar Cell 1 Gnd, to Gnd
About the Name
I messed up the top when using the Dremel to etching a space for the solar cell and diode. The side of the Dremel touched down and scuffed the surface. “Well, looks like we will have to call it scuff,” said Joe.
