The white bottle cap is the RGB LED that blinks green for each command loop when we are healthy, once in blue when a command is received, and in red if we have lost the network. Will also blink SOS if the 'bot software has crashed.
The only major change that I am entertaining at this point is to drive the servo stalk and ultrasonic range finder directly from the RPi GPIO instead of suffering the latency of going through the Arduino.
I would like to move the compass to a direct interface but am not sure about the I2C integration.
Your blog has inspired me to attempt to make something interresting with my newly aquired raspberry pi. Haven't decided on a platform or anything yet, but I'm looking forward to it!
ReplyDeleteI am certainly enjoying mine! In fact, the original one that I ordered, but got frustrated waiting for, is now on the way so I may end up with two of them. I was going to eBay it but am now thinking "what can I do with another one"?
