I guess another option is to use an arduino mega. >.< but I am a conservative person and tend to make large purchases just in case. I bought an 24ch one, but obviously didn't need all 24 ch, not sure why I did that. ~ Drill and drill bit, ideally also a drill press ~ Ratchet or socket wrench for 4-40 bolts ~ Ideally, a vice or clamp ~ Ideally, a horizontal bandsaw ~Optional: Scrap 2x4 wood ~ Measuring instrument, ruler or vastly preferably calipers ~ Optional: Deburring tool Required items (electronics): ~ Arduino nano + breadboard + male headers (for the servos) ~ Either 6 Y-splitter servo cables or a pololu serial servo controller (because the default arduino library only supports 12 servos). At least 3/8'' long (enough for the 1/4'' plastic or Al and a locknut to fit on there). ~ Screwdriver ~ 4-40 bolts and locknuts (about 48 of them), or whatever bolts fit through your servo flange holes (the side holes). I used 6 Hitec-311 and 12 Vigor VS-2 servos because that was what I could scavenge for. I used 1/4'' ABS) ~ About 6'' of ~ 18 R/C servos (I recommend standard size, I've seen hexapods with the tiny 9g servos, but I think that it would be hard to cut out the holes for such servos by hand), complete with the "+" shaped servo horns and servo center screws that should come with the kit. Required items (hardware): ~ Vertical bandsaw (unless you have a lot of patience with a razor) ~ 1/4'' plastic sheet (any reasonable thickness such that the plastic is fairly rigid is fine. A set of blog posts exists here: I would specifically recommend this post: A video explaining the design process in 7 minutes (this instructables goes into the construction but not the design): and here is a video of it at the end: The first few pictures on there are from Aluminum Hexalinkagepod, based off of the Parallax boebot hexapod. A complete picture set of the build process exists here: 2.007 Hexapod (Spring 2011). No theoretical underpinnings for designing your own hexapod are really explained here. Again, this is documentation of the exact steps involved in a semi-working project. Additionally, I did not implement remote controls so all the code runs autonomously (zero input, multiple output system). The wires and six legs make it look complicated, but since the legs are just the same thing repeated 6 times, it's simpler than it appears. I built this for a sophomore mechanical engineering class at MIT. I won't be improving this project any time soon, and people seem to visit my blog from pololu, so I thought I'd go ahead and document it as is. The mechanical design is not great, but it is very much in the KISS (keep it stupidly simple) style and should be doable in a weekend for builders of novice to medium experience. Hello, Here is a simple hexapod that can be built by hand very quickly.
