Makes life easier by cleaning up all those messy wires in your prototyping. hanging off the side makes it easy to fit in a two part, 3D printed case. We use it as part of development for our Sixi Robot Arm.
You can get all the details and order them for you or a friend right now.
From any web-enabled desktop browser you can experiment with the kinematics of a robot arm at http://robot.glumb.de/
The author, Maximilian Beck, has made all the code available online at https://github.com/glumb/robot-gui. Be sure to check out his other interesting projects on github, too.
Makelangelo is a wall hanging, mural drawing machine. There is a motor on the top left and top right of the wall, and belts hang down from there to the pen. Tension caused by gravity keeps the belt on the pulley.
To draw on the entire wall you need a belt long enough for the pen to reach the bottom corners, going diagonally across the drawing area. That means if the pen were to be in the middle and drop all the way to the bottom it would hit the floor.
When the machine tries to find home by touching limit switches, the pen holder hits the floor as described. Gravity stops, tension is lost, and the machine becomes confused.
This 3D printed tensioner fits a roller skate bearing (8x22x7) and holds the bearing against the belt, gently pinching it against the pulley. This prevents skipping and allows large machines to find home.
This has an added bonus of letting the machine accelerate faster without skipping.
Print two (one for each bearing) and then fit them onto the two corners and enjoy!

The 2019 Vancouver Maker fair was a hit, and so was the Sixi Robot! We spent the day interviewing attendees about what they would do with a robot arm, and we’ll use that feedback to make use-case videos.
Our booth was planned well in advance and we even brought a carpet to stand on.
Everything technical was very smooth. The robot shipped in perfect working order and didn’t misbehave the entire day. I had a couple of software glitches, which were quickly solved by restarting the app. The venue was set up such that we had to flip our booth design and reprogram the robot for the new position. Who could have foreseen that one, right?
The venue didn’t give us any chairs for the day, but we were having too much fun to sit down.
Here’s what it looked like from the camera’s point of view. Sometimes you can see the selfie in the mirror in the selfie in the mirror in the selfie in the mirror and then it’s too small to tell what’s going on.
We felt really inspired by all the great people who came out to share and enjoy. Definitely something we’d consider doing again. Go check out your local maker fair!
