Let's make an InchWorm CrawlerBot #2


This is the build video in which I make an InchWorm CrawlerBot using the plastic chassis from a DVD drive that I stripped out from an external DVD reader/writer unit. It is very similar to the CrawlerBot I made a few days ago and uses the same simple circuit based around a mechanical toggle switch. This time I don't use wheels to provide the forward motion. Instead I use strips of plastic cut from a pop bottle.

If you have a question it is probably worth reading this video description first because the answer may already be here. To help you find my videos I made two search guides https://youtu.be/ceBSOoOHcgw or https://youtu.be/Zj4UgwkwYRk or checkout my playlists page https://www.youtube.com/user/GrandadI...

Generally my projects are for my grandchildren to enjoy. OK, I enjoy them too. If anybody else likes them, that is a bonus. I like to keep my work as simple and basic as possible so that it can be copied easily and improved by anybody who wants to try themselves. I recycle or repurpose items rather than buy new and when I do buy I like to keep it cheap.
