This is my first attempt at making a multi-legged insect inspired robot. I hope to use HOPE as a learning vehicle to a larger bot project.
It's a lie, this isn't really step 1.. I have iterated several servo layouts (in fact you can see glue marks from past failures in one of the pictures). I started thinking about this years before home 3D printers were even a reality and have failed cutting reliably 2 sheets of ABS, dozens of chop sticks, and even wood on numerous occasions. I honestly gave up on this for about a year due to seeing no way to fulfill my desires of symmetry. Forward to November 2016 and welcoming a Ultimaker 3 into my home and all the sudden the prospect of completing this isn't doomed.
So far I have lied and now I must admit I cheated on the project already, too. However in my defense I wanted to test my new printer, my Solidworks skills are limited , and so I came across a project on thingverse(quite by accident) that was exactly the style and shape I wanted and designed to fit my servos. So I began printing the lower leg portion. The printer passed my test with 6 prints, 0 failures, and only one little corner that didn't stick right on one leg.
I started with the lower leg portion because I am of the belief that it is the most important part of any walking robot. Well the feet more so than leg but on a hexapod it is basically the same thing.
The legs are attached to their servo using 2*(2Mx10mm Bolts & Nuts)
In truth step 1 should probably be drawing out some designs and perhaps doing some math etc etc etc... and I have made some crude cave man like drawings; more suited to use of crayon than pencil, calipers, protractors, straight edges, and other fancy implements. However I wasn't settled on what 3d software until recently and even still I am fighting Solidworks vs Inventor.
Now step 2 will become the actual planning phase, because I must begin looking at leg length and gait.
TL;DR = I all but randomly chose some leg piece and printed it 6 times. Time to design around them.
