@David: Of course you could use that 4th motor to rotate the camera......then you can see where you're coming from as well.....

The great thing about the Adafruit motor controller boards is that they are stackable -- and they are controlled via I2C so the whole stack consumes only twoi pins (you just have to chang ethe I2C address of each board.

I have thought about having a "turret" holding th evision sendor on the top of the base, where the turret can rotate independently ... but lets not get too far ahead of ourselves here -- I haven't even got the base working yet :-)

@Max...you're making my head spin (along with your robot)... :-)   But thanks for all that - I can see where you're going with this....and I wondered about making one direction "front" if you are using a camera.  Of course you could use that 4th motor to rotate the camera......then you can see where you're coming from as well.....

Are you volunteering? LOL

>> using Genetic Algorithms to learn the best way to do things...

Since they are goal driven , you best bet is leaving the programming to an expert in laziness. Or is it ?

@Duane: Someone at Skynet would like to have a word with you.

He's already been round -- a rather tall, imposting man in a black leather jacket with a strangely glowing red eye -- he said that I was doing a great job and that I should go ahead.

@DrFPGA: How about using an algorithm that 'learns' how to move in a particular direction? The robot starts out with only some simple functions for wheel control and builds up functions for specific directions and speeds after 'trying' out some combinations. 'Winning' combinations become the next 'best' function for moving that way. Let the robot do the work of coding by programming itself...

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
