I was forced into rebuilding UniBot in order to take a photo of it for nxtlog. However, I've never liked a straight rebuild so took the opportunity to improve it. Very pleased with the results - much more stable and strong, and no 'wobble' as it drives forward (a problem you can clearly see on the video of UniBot1).
After seeing some of the discussion on the nxtasy forums regarding the first UniBot, I thought I would add some better "attachment points" and use only elements from the NXT Retail Set. This should help people with only one NXT Set (myself included) potentially build some "higher functionality" robots - as using UniBot as a mobile base effectively frees-up a motor from turning duties, allowing for more complicated 2-motor mechanisms on top.
I'd love to hear of anyone who uses UniBot2 in this way. Please give me a shout if you do.
The LDD file for UniBot2 will be available on nxtlog shortly.

Wow, that looks very, VERY promising. I just can't wait until the LDD is on NXTLog. I am dying to build it. I read 222Doc's article thingy on the floating worm, and I was using the model in the figures to try and build a vehicle like that. Unfortunately, it was very unstable, and so I think I'll just wait for the LDD of your robot, and see how you did it. I think this is an excellent project, and you did a very good job. KUTGW!
Can you make some photo instructions of it, for those of us who don't have LDD and still want to build it?
LDD is free to download off the Lego website and is a brilliant bit of software. I would really recommend getting it.
Unfortunately, producing photo instructions is very time-consuming compared with building an LDD model and can be a bit of a nightmare for more complicated models.
I build this robot, run it and i heard that gears is "clicking". What's wrong?
Not sure. Sounds like you've got some gears slipping - probably the last gears before the wheels (if that makes sense), they would occasionally slip on mine but generally it worked fine.
