The image of my bot here is why I don't use my webcam much! :-) 

But you can get a basic idea what it looks like. The box in front contains 4 AA cells, the 9 volt battery is behind the barely distinguisable Sharp IR range-finder. The blue pc board is the Uno (Arduino). The black cylinder object in the back is a piezo-buzzer.

Chumby - Ro-Bot-X's Living Room & MyRobotLab

Ro-Bot-X and I are working together even though we are 2500 miles away !

Hey Look... I can see Ro-Bot-X's living room through the eye of the bot he's currently working on ! (Hopefully he won't mind me posting it :) )

sensor jitter problems? Let's fight back.

I wrote a tiny function in Arduino-C for my sensor-jitter problems. You can smooth out your sensor readings with this little function. You can input the smoothness and then get back the smoothed sensor value.

If somebody needs it - here it is:

Driving servos from GPIO

The next challenge is to drive a servo from the RouterStation board.  This servo will eventually turn the box around a pole.

I understand that there are lots of serial and usb servo control options for servos. But I also understand that one can use a GPIO pin to directly signal a single servo, which is all I need.  Save some dollars :)

Wireless repeater part working

Got the wireless repeater parts up and running.  The default firmware on the routerstation doesn't have the ath9k driver that the R52nm cards need.  That's ok, I was able to flash in the updated OpenWRT 'backfire' using the 10.03 candidate from the openwrt site (using the 'factory.bin image which I understand you have to use the first time).
