Larry Worley’s Crawler

March 18, 2014 · by David Gilbert · Erector Sets, Vehicles & Transport, Worley, Larry

This is my latest model, which I call “The Crawler”. It was originally designed as a “Moon Walker” and its legs were quite lengthy. However, when it was up at its highest point, about 10 inches, it was terribly unstable. The center of gravity while up there at its height, combined with the weight of the two A49 motors, would collapse and sometimes bend parts.

I had even planned to try to make it climb stairs, but that didn’t work out either. Maybe one day I can figure out a design to make all that work and even climb stairs.

My dog, Tid-bit, doesn’t like it. He barks at it and runs back and forth, threatening to attack it. Probably due to the noise from it as it is a bit loud.

I was planning on presenting this at the June 2011 convention, but alas, I cannot make it, so I just sent it in for posting.

Originally, it had different transmissions, chain drives, etc., as shown in the last picture, but I had to settle on the low-to-the-ground design due to its rickety performance while lifting up and lowering back down.
