I am a robotic enthusiast and therefore quite excited about the bug development. Also, that i read requests about some servo connector module made me think a bit.

It would be really cool to get some robots going without the need do develope all the hardware (in terms of computational hardware) by oneself. One might say: Isn’t that what LEGO Mindstorms is all about? But besides being a nice robot toy, it has some severe limitations. And I think BUG has the ability to overcome all sorts of restrictions just because it is so open to change.

So why did I put this up in "Suggestion Box" and not somewhere offtopic?
Well, because in the end I have some ideas which might be if nothing else some food for thought.

So far I have seen the BUG with only one camera module connected at a time. If not allready the case, it would be cool to get two camera modules working in order to enable stereoscopic vision. I imagine that this would require some serious amount of cpu power, therefore there are a couple of things to think of.
One would be, to connect two BUGs and let one do the stereo vision and environment modelling, and the other to do the planning and overall thinking.
On the other hand, maybe there could be specialized modules that have some sort of geometic and vision centered computing units (with special CPUs and memory). Those could do the modelling and picture analysis in order to leave the BUG mainly busy with the plentiful tasks of a robotic life. (Here I must say, I have now idea about what the connectors are capable in matters of bandwith from one module to another. It would be a shame it that would become the bottleneck.)

As mentioned the servo module above, I think it would be good to have besides such a dedicated module also some connector module which could be more software definable – to use besides PWM also Voltage outcome to regulate actuators. (If you want to use Nitinol for example.)
And in case a robot uses motors which draws some ampere, it might be goog to be able to have those powered by extra bateries. Actually, it might generally be a good idea to have all actuators be fed (or feedable) by an external source.
