Practical Uses of Artificial Neural Nets?

I have read over the theory behind neural networks and found open source code to help implement them in various ways.

I was wondering if any LMR users out there had put neural nets to any practical uses on their projects?  What kind of neural net did you implement?  For what purposes?  Was it worth the effort?  What problems in robotics do you think are well suited to neural nets?

Hello guys,

Some of you might know that I had submitted my entry as part of the Village to Raise a Child Campaign. It's about changing the way Nepal learns through building robots.

The campaign has reached the voting phase and I am in need of your support.

T'REX tank chassis

It's been a long time coming but the T'REX robot chassis is here!

I've just been testing the final product so I thought I would post a few photos of the new chassis. The chassis is aluminium with a black powder coating. The tracks and struts are zinc with a black anodized finish. The wheels are zinc with a chrome finish.

Need help with Rover 5 robot

 

I had Rover 5 robot with dimensions below

 

Gearbox ratio: 86.8:1

Encoder type: Quadrature

Encoder resolution: 1000 state changes per 3 wheel rotations

 

Can I build any other robot types with this kit?

I recently got the make: it robotics starter kit but I was wondering it there any other things I can create with the starter kit only and maybe a few extra parts? The two robots are kind of boring now. I have provided the Radio Shack link so you can see the parts it comes with!

A robot shop in a van?

I'm curious. If I were to choose to be living in a van, how much of a robot shop could I take with me in a usable form?

I'm talking general tools including basic woodworking and metalworking. A 3d printer goes without saying.

And yes, I'd need enough space left over to live and perhaps even entertain in.

The budget for this thought experiment is $50,000 US and includes the large van or small Winnebago. At most two people would have to live and work in this. Any help in figuring out if this is possible and how to do it would be appreciated.
