A design document of sorts. |
A big part of his designed behavior is centered on autonomous operation. Ideally I should be able to plug in the battery and never have to look at him again (Although that would be a little cruel). But, before I get to the electronics and microcontroller I have to build a suitable chassis for EDGAR so he can roll around my apartment in style. I started with the materials I had on hand from a kit I tore apart a few months ago:
Two modified servos and a janky ball bearing wheel. |
It looks nice and smooth but doesn't capture the servo mounts! |
The third one though, captured the servo mount and held it in place to the point where I am seriously considering skipping the screws entirely on the final design:
As you can see the notch is on the correct side and I added additional bracing to counter the bending when I slip it over the servo:
Now that I have a set of baller braces for EDGAR I integrate them into a single piece chassis with a small extension to accommodate the ball bearing wheel in the front:
