Catweazel, AKA Michael Leefers, was kind enough to create computer-rendered instructions for building TrotBot in LEGO, and share them with us! Instead of using 3/16" aluminum rods to prevent TrotBot's inner frame from sagging, Catweazel cleverly added a Technic beam to connect the inner frame to the outer frame, which helps to prevent the plastic support axles from bowing. This is the same solution I was planning on using for the support rods of my large bamboo TrotBot - great stuff!
You can access or download Catweazel's instructions and efficiently purchase parts via his Rebrickable page. Thank you Mr. Leefers!
Welcome to DIYWalkers! My name is Ben Vagle, I'm 17 years old and I've been building mechanical walkers for the past 4 years, at both LEGO-scale, and SUV-scale. 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!
