NXT 2.0 - One Kit Segway



Dave over at www.nxtprograms.com recently put up instructions and programs for a Segway - built with a single NXT 2.0 set and programmed with NXT-G using a simple PID loop. Very cool!



Great job, and thanks!

Awesome work. I didn't think that the colour/light sensor was sensitive enough, or NXT software (on the standard firmware) fast enough to do this. Very nicely done.

Dave, very very impressive, and most certainly one of the greatest projects I've seen so far with a single NXT 2 kit.

That's is really really cool. Thanks for sharing!!!

Thanks all. I initially didn't think NXT-G was going to be fast enough either, but the 2.0 version with the 1.28 firmware is significantly faster (I timed it as 3x faster for this task than NXT-G 1.1 with 1.05 firmware). Math and Variable blocks are already very fast (in both versions it turns out), so the PID calculations needed are not a problem at all. I think the key is that now the Color Sensor and Motor blocks are a lot faster (the Light Sensor block is also a lot faster now too).

And thanks for the post Richard!

Saw this and built it tonight. It works on my kitchen counter with no interference from an overhead fluorescent light. Finding an upright resting position was a bit hard in the 3 seconds, so I upped it to 5. It is fun to watch! Thanks Dave for the fun design, the clear instructions, and the great program!

This robot is featured on the front page of YouTube today.

Congratulations, Dave!
