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.
RW2i - Internal mount, and new shaft hol...

We're still digging out the new inventory, and the next addition to the Solarbotics lineup is the RW2i, which is the same profile and rolling size as our very popular RW2, but is designed with a narrow hub.
We're able to do this by moving the set-screw hole inside the hub, so to cinch the screw down, you have to remove the tire from the hub, which is a pretty easy process.
We had planned to make the internal cut-out of the RW2i to allow the installation of a GM11a-14a style motor to the open side, but the manufacturing tolerance was a wee off, and we can't quite make them fit. Fortunately, it's a pretty simple process to file the edges of a GM11a-14a motor to make it fit, which has the added benefit of making the brass edges of the gearbox act as brass bushings that assist wheel alignment.
Also new to the RW2 and RW2i wheels is a new hole diameter! We've had many requests for alternate shaft sizes, so we had a limited portion of both these hubs manufactured with a 1/16" pilot hole so you can drill it out to whatever size you need!

Cool Link Wednesday: Yana Edition
About a million years ago (and by that, we mean 3-4) we had a crazy French intern called Jerome. He had a squiggly beard and liked to exclaim "SUPER COOL!" whenever he saw anything that caught his attention. But because he came up with neat stuff like the BeetleBot, we let him stick around. Even […]
Protel v2.8 Demo Disks
This is a very nice little demo package from Protel of a PCB layout program. It's an older package (they don't even have this on their website anymore), but works on any windows platform, unlike their current demo versions.
Solarbotics has been operating for more than 25 years, bringing electronics know-how and supplies to both the electronics professional and hobbyist. We'll be happy to help you too!
