Week TechVideo, 2010 #46 - RC Walker

Lesley Hisgen (hisgen01) shows his nice LEGO Technic RC Walker.

It is a remote controlled and articulated hexapod, making use of PF elements only. Thus not involving any kind of programmable device like NXT, RCX or similar.
The "robot" uses one XL-motor to drive the walking function and one M-motor for steering.
Steering function is achieved by moving the body articulations.



In the video description, Lesley mentions the walker to move a bit slow. However and if the video is not accelerated, I'd say it moves pretty fast.
Anyway, looking forward to see the promised improvements to come.
It looks simple but simultaneously one of the most effective LEGO walkers I've ever seen.

Reminds me of a 4 legged robot with articulated steering I once built. Its really great!

Never seen Menno Gorter's [url=http://www.youtube.com/watch?v=5lzKTmEfRdA]geared-ant[/url]?
[url=http://www.brickshelf.com/cgi-bin/gallery.cgi?f=166641]Or his older walker's ?[/url]

So this idea isn't totally new since Menno's first articulated version is from 1982, but it looks good for sure!

Oh yes, I recall it!

Maybe we could say that Lesley design distinguishes for the three articulated sections.

The three articulated section solution seems to improve steering performance and speed as well.


However an articulated walker in '82 is really astonishing!!!
Menno's '82 Walker

As well as the ant from Meeno, on the video above mentioned. :)

I'm typically not impressed by these "rotation-based-leg walkers", but I've to admit this one is really nicely realized. Love it! great job!

This is a good example of a simple idea that is well executed to give impressive and smooth performance. It would be a good choice for a b-model I think. I like it!

Inspirational stuff - I've just built a 6-legged walker with a different turning method (stride length changing), and i think i'll make this the next project.

Thank you for commenting on my video. In fact I just found out about this blog and my videos being on it. I'm happy to see that people are interested in my designs. Maybe, if I think this webpage is suitable for it, I will put my new videos straight on it.
