Reykjavík University Stewart Platform controlled by a DIY joystick

2015-11-16 Dan

Kristófer Reykjalín shared a video of a Rotary Stewart Platform v2 driven from a home made joystick. A student group studying Mechatronics at Reykjavík University in Iceland used the Stewart Platform to demonstrate what they’ve been studying about control theory.

The team included Kristófer Reykjalín Þorláksson, Haukur Hlíðberg, and Stefán Óli Valdimarsson. Their professor is Joseph Timothy Foley.

Their code is uploaded on Github. Kristófer says the design files for the joystick will be there soon, too are also part of the Github package.

Paul says,

I’m a Makelangelo believer. It’s everything STEM is supposed to be. STEM is so huge in the states, that the term is often used to get attention. Makelangelo is the real deal.

We couldn’t say it better ourselves. Thanks, Paul. You rock!

Robot Arm Adapter Dimension Diagram

2015-09-08 Dan

Arm5 robot arm tool adapter

We’re using a normal camera quick release for this robot arm because we want to follow the KISS principle. With these diagrams in millimeters [and inches] you should be able to model the adapter and then 3D print it, mill it, add it to a tool design, or more. The only rule to remember with the adapter is this: your tool should never go “below” the top edge of the adapter, or the arm might not be able to grab the adapter.

So what kind of tools could you make for your robot arm? Here are a few suggestions:

A Dremel mount:

A 3D printer nozzle:

A gripper:

A vacuum nozzle with a suction cup:

If you can make a tool, share it in our Evil Minion forum or bring it to the World Maker Fair 2015. I’d love to see what you can do.
