This the only site that I know of that has a Turbot. A turbot is a nasty little bot that kills other robots (rips out wires). First made when Mark Tilden was trying to make robots that would combine, he added arms on them to help the combine. he left about three of these alone and the destoryed some bots. Turbots have evolved into this.
This I couldn't help, but "borrow" from the egroups message archive that has the e-mail messages with all sorts of info. This simple circut makes a snake just add more slaves to the circut. Look at solarbotics robot galleries to learn more about this and the turbot. The head for this is the head section. Circut by Wilf Righter
