This circuit is used to create a simple "edgebot" sumo robot. Being an edgebot refers that it will repeat the same backup/turn/go forward action when it's single edge sensor detects the edge of the ring. This version of the circuit is quite simple, and always turns the same way.
Catalog glitches...

Grrr... Time to start handing out the 1000 lashes with a wet noodle. There's a few pricing errors in the new catalog 6:
- The RM2 motor is not 2 for $10.75/ea CDN - it's 1 for $3.40 or 2 for $2.85/ea CDN
- The SC2422 solar cell is not 2 for 2.55/ea USD - it's 2 for $3.25/ea USD
- The GM8 and GM9 gear motors are not $5.50/ea - they're $10.55/ea CDN
Sorry about the confusion, folks. I wish we could afford to honour the under-pricing and correct just the over-pricing, but we have a staff to feed and free community servers (www.solarbotics.net) to support!
