looks promising
keep us posted, this looks like it has a lot of potential.

Internet connectivity
Does the mobile robot really need the internet connectivity?

While a connection to the internet isn’t strictly necessary, a wireless network connection is very useful. It allows:

• remote uploading and debugging of software
• manual override (remote control)
• image capture or video streaming from the webcam for surveillance
• offloading computationally demanding tasks like speech recognition to a more powerful computer

Pan - tilt camera mount

I’ve now made a pan-tilt mount for the webcam. Basically it’s the guts of a Playstation Eye webcam mounted to two home made aluminium brackets, driven by a mini and micro servo. Details of the construction are at http://mechomaniac.com/node/57

I saw some OpenCV pictures of code on your site. I love opencv - will you be sending the pictures to a computer? I don’t know many micro-controllers that can preform “much” meaningful processing on a image stream.

Great work.

Keep it up !

Thanks! They’re not pretty, but seem to be functional at least. I considered getting some Lynxmotion brackets, but the cost and time to get them to Austraia wasn’t worth it for now.

I’m actually running OpenCV
I’m actually running OpenCV on the Beagleboard itself. With 256Mb RAM and a 600MHz CPU it should be able to handle the image processing on-board, though I don’t think that OpenCV has been very well optimized for the ARM architecture. The Beagleboard also has a DSP core and some people are working on using that for accerlerating image processing tasks, so there’s a lot of potential.

Mini Micro Pico ATX

Interesting - what benefits would using a beagleboard vs a mini/micro/pico/ atx ? I am not really familiar with ARM architecture, although I remember seeing it as one of the possible kernel builds when I recompile my kernel.

Initially I see $145 for the beagleboard vs $66 for a mini atx - Is the beagleboard mor catered to digitial & analog io? DSP Core? Digitial Signal Processing?

I found a link once where a group has optimized OpenCV to run 10 X faster on a playstation since it has hardware catered to graphics processing (Awesome!)

Very interested in seeing your progress.

I have been working on a java robot framework - with a JNA implementation (some very smart guy (Samuel Audet) wrote) to opencv. I found this just recently. Previously I was using JNI which has been a pain in the rear.

Anyhoo,

keep up the good work !

Good to see another LMRite

Good to see another LMRite from down under ^^b

Also cool robot! Was there a specific reason you chose the playstation cam over others, or was it just on hand?
