Still working even though not making much progress, currently I’m working on things to increase precision in the parts themselves as I haven’t thought of any ways to improve the mechanics.

The main problem I’m having is that small deflections in the part where the leg attaches to the driver results in significant problems in the knee area. I have been able to improve this with precision but I think to make it work well I think I need to redesign something to hold the knee joint parallel

I’m continuing to make small improvements so hopefully I come up with something soon!

Capstone #6: Solid

<-<- FIRST || <- PREV || NEXT ->

CAD is nearly done, and the design is 95% there. There's still some improvements to be made. Big 'ol hand to our CAD team especially for bringing this to life. Lets explore under the cut

There's 2 main parts of this thing. The main body has the fans and wheels. The gantry on top does all the doodling. Let's pop the top off.

The cover and walls are purely aesthetic and keeps the dust out. Originally the cover is held on using snap buttons, but that's been changed to the tiniest magnets pocket change can buy. The base plate is made from thin wood, or we've been exploring carbon fiber (but that's proven to be mad expensive for basically no gain. Like 400+$ expensive).

The wheels are servos, the fans sit side by side and run off wall outlet power. (Try making these drone motors that normally run off batteries, and make them run off a wall outlet. Sounds easy right? Good luck. It's been a time doing it. They eat something like 12-16v at 40-60+ amps... *each*). It's got tiny nubs on the bottom to stabilize it, because with only 2 wheels, it's going to want to rock side to side. It'll have some distance sensors on the sides to find where it is on the wall, and an accelerometer to find how it's tilted. I'm personally a little worried the vibrations from the fans will make the accelerometer unreliable, but we'll find out about that later. The whole thing will be controlled by an Arduino Mega.

Smooving over to the gantry, both axis will be on rails purchased from Igus. The rails are made from hard anodized aluminum, while the carriages are made from diecast zinc and some slippery bearing plastic. It's then pulled around by timing belts and steppers. We modified both axis a tad by reducing the rail size to the smallest ones Igus offers, and giving the horizontal axis 2 rails for more stability (The bearing situation on the timing belts were improved too)

The printer head uses an electro-magnet to pull the pen down. There are guide pins with springs to, well, guide and spring return the head. There are also stop screws that set the maximum engagement and disengagement. (The travel distance is kinda exaggerated here tho. The actual travel distance will be as little as possible. Like 3-4mm)

All in all, the bot body is something like 300 x 500mm, 60mm thick (+ 55mm for the fan tails), with a print area of 150 x 150mm. We've tried to cut as much weight as possible, and are looking at about 1.2kg or a little lighter than a small toaster

As a bonus pic, here's an early concept. This one uses a lead screw for the X, and a shaft and timing belt for the Y. If you're wondering what stops the axis from pivoting, it would have been some gibs located behind both axis. Commonly used on dovetails, a gib is when you intentionally design in a large gap between your mating surfaces, and shove a thin plate in there with setscrews to take up the slack. Look at the ways of basically any milling machine or lathe, and chances are you'll see one!

This last modification has been the most difficult so far, mainly because I needed three layers rotating in different ways without interference, but I finally have a configuration i think would work well; though it still needs minor adjustments.

I have also used up the initial board I got for this project and I'm ordering much better material this time, though its going to take a week to arrive, I'd likely need it anyways as a still need to get the car attachment mechanism on each side as well as remaking everything to be ready for the cutter. I have a lot more work to do before this next step is out but i have time before school and work starts up again in a couple weeks so i think ill have this edition done soon!
