Here is Little Joe, a biped walker. He was inspired originally by the work of Joe Nagata, but the feet are probably the only bit of Joe’s original that survives.

Little Joe has a pretty smooth and reliable walking action going on which you can see on video here. I’m very pleased with how he turned out. Just wish I’d got him finished in time for the NXTlog competition!

There’s not many instruction sets for bipeds out there (or not that I could find anyway). Hopefully this LDD file will come in useful.

If anyone does build Little Joe, I’d love to hear how you get on…
