Rosmo is a project to make small openhardware robots for educational and hobbyist use. We aim to design capable robots which can be assembled without soldering. It’s a modular set of open-hardware components that can be assembled into robots of different...
I was looking at the nice little solar cell built into my calculator, and thought of something: for the people that would say "I'd (almost) never turn those LCDs on", what if a different surface could still have a use compared to a inert slab of material?...
Progress update: Basically, what happened is that I spawned those vias around the BLDC controller to see what kind of space I needed to have for ICs. I extended the PCB 5mm, which gave me loads of room. Looking at the Tetrinsic 3D model, I reduced...
Just behind the axle I slid in some bar stock that was tapped. I forgot about it. Adjustable laser mount! There is a nice spot in the front there for a hunk of spinning iron for imparting roll into the body. I am not sure how effective...
Enbiggening the ProjectUltimately this project was spurred by the realization that— while one is tough— having two or more children can absolutely tank a healthy person's ability to exercise. Research throughout the project has confirmed that...
5/3/2018 Log #1 Today I present some pictures of some of the driver modules I have come to refer to as PowerPACks. In essence, PAC means Power Application Controller, and I must say this is an Active-Semi Inc's Trade Mark. I call my modules PowerPACks...
The second , most important part of the muscle module is the bidirectional , miniature gear pump . After a lengthy search I found a pump which is almost perfect for this project - a miniature gear pump made by MAGOM HRC company , and intended to be used...
Background Autodesk Inventor Parametric Design Cycloidal Gear (from my other project) N_ (number of rollers)= 21 ul number of teeth = number of rollers - 1 E_ (eccentricity) = 1 mm Rr_ (radius of rollers) = 2 mm R_ (radius of Rotor) = 25 mm x(t)...
Right now I'm reading how Plover got started through blog posts written by the project founder and it sounds like her and I are on the same page. I'm still at the 2010 blogs though, when multi-touch touchscreens were talked about as the next...
[L] = [EM] = Electronic designSo I've found out what I need to do to connect the off-board MAX98357 via I2S and I've got an idea to use the same type of ribbon cable (and pad) as the 1.47" LCD: I've used the GND pins to split the power, I2C and...
Summary:My first order of parts came in today. I am starting with the basics for right now. My goal is to get a BLDC motor driver up and running for 1 motor with the same MCU that will be used on the GatorQuad, and then go from there. This will allow...
At this stage I had a simple proof-of-concept, but with some flaws I wanted to address:I didn't like the Turtlebot-shape of the robot, I wanted a more close to human size robot (around 1m50 / 1m60) which could carry a load.The wheels mounting brackets...
FAZE4 As some of you may know I also designed 2 other 3D-printed DIY robot arms; Faze4 and CM6. I would say Faze4 did well in the open-source community and has an active user base. It is mostly used by students as thesis work and just like a DIY robot...
Two weeks before the EMFcamp 2018 I learned on Twitter about Hacky Racer. And because I'm quite into moving objects, I had to join the race. I already have some moving objects, a BobbyCar, a moving armchair, but all of these are rather unpractical to...
Alright! So in my last log I tore into the Pacific Hydrostar pump and got to the juicy insides. First, I decided to go ahead and cut off the armature from the main shaft and then grind in a flat to create a D shaft. No turning back now! Instead...
