NoodleFeet finally took his first few wobbly steps a couple of weeks ago. I’m so happy to have finally wrapped my head around a walk cycle that works in spite of his obvious physical limitations; wobbly joints, weak motors, and top-heaviness.
Now that this milestone has been reached, he can no longer remain in his weak proto-form any longer. Noodle must grow to become the powerful little leg-hugging monster he was always destined to be. PHASE 2 BEGINS!!!
The most important upgrade I needed to make was to his brain. A custom PCB would replace the current Arduino and allow Noodle all of the other behaviors and abilities he would like to have, such as beeping, balancing, and of course… actually seeing!
With help, I tossed together a fully loaded board sporting an ATMEGA328 that houses the potential for all of those systems, and will also connect to a Raspberry Pi when I’m ready to dip my toes in OpenCV (Noodle’s ability to see and comprehend what he sees). Not only is this new Noodle Brain far more capable… it also looks sufficiently Noodle-some too. I completely embraced the “curve” trace tool. (It’s ramen-esque! – heh, get it?):
Also about two weeks ago, I applied to give a talk at HackaDay’s first SuperConference in San Francisco. I proposed to tell all about my process designing and building mechanical forms that are inspired by character illustrations… (with Noodle being my primary example)! I’m excited to say that I was accepted. I have a new thing to look forward to this fall; it will be my first talk ever 😉
Any how, all the more reason to do some more upgrades to my Noodle child! Upon making my travel arrangements for San Fran, I also ordered a full set of high torque metal gear servos to replace the so-so resin ones that he’s made do with so far. This ultimately involved completely dismantling Noodle. Knowing he wouldn’t like this, I made sure to take out his old brain first:
When my fabs arrived, I quickly soldered one up and installed it this week along with the Raspberry Pi (attached to the back of the brain):
Noodle as he stands now, has the power to punch through walls with his feet, the ability to balance, beep, and eventually see- once the raspberry pi camera module arrives from SparkFun. Here’s a video of the first wave of upgrades taking place:
I can now return to honing his walk cycle… so that he’ll be a bit more mobile for the SuperCon next month. It’s quite possible I’ll still be replacing some of his plastic parts to remove more of his new-born wobble… but we’ll see.
