Klann's Mechanical Spider was the first walker I ever built. I like it since it's robust and not too complicated (as mechanical walkers go).
Here's a simulation using the ver 2 LEGO beams as the bar lengths. The python script that made this sim can be downloaded here.
Welcome to DIYWalkers! I'm Ben Vagle, and I've been building mechanical walkers since I was 11 years old, both big and small. I started this blog to share what I've learned, and to collaborate with you. Let's see if we can take walkers to the next level!
