It's been a while.. Well, time just seem to disappear when kids, family and work require the most of you.
Not so creative title.. and what to call my current project isn't that important really. I did start on a simple hexapod design a couple of years ago, that ended due to some distractions and suddenly my Autodesk 123D files disappeared from the "sky".
Meanwhile I've been working on a new gait-algorithm for hexapod robots (codename DynaZgait). I did post some short vids on my Instagram. Earlier this year I decided to learn 3D printing and bought a very cheap Wanhao Duplicator i3. I've done all of the most common modifications and upgrades. So far I'm satisfied with the result and print quality.
As you can see I've even added an extra heater in the cabinet, useful when printing ABS during the cold winter.
Another project was a new remote controller based on the code used on the Arbotix Commander 2.
My next plan for a remote is make a much smaller one using some other very nice 3-axis gimbals from Turnigy.
When it comes to CAD I'm a bit noob. At first I tried Autodesk 123D, but I found a bit to limiting. Then I moved over to Inventor and found that OK, but a bit cumbersome.. After that I tried Fusion 360 and found it to be a really awesome tool and easy to use/learn.
So far I've designed a small and simple hexapod body containing a 3S 5000mAh LiPo, Teensy3.6 + Kurt's T3.1 breakoutboard and the coxa servos (MX-64).
The CAD images is a bit easier to see than the photos (poor light). The battery simply slide inside the body between the body sections:
A couple of photos of the final result:
The body sections are printed in ABS and "Acetone vapor-treated". The final result is very strong and solid.
Next step is the leg design. I'm planning to first use the Interbotix Tibia's as a Femur, lol.
A question: Does anyone know where to get 3D files (.stl) of this bracket? I've already bought six of them but it would be nice to import them into Fusion 360 at first. I'm planning to design the Tibia's on CAD and print them in ABS.
In the future I'll move over to a more advanced hexapod design. With limited free time available I just have to learn CAD a lot more and this project is a good start.
I hope to keep posting progress now and then..
