Build a Raspberry Pi-controlled "Stewart Platform"

As part of a project to explore robotic body language, Radames Ajna is working on a device to move a mobil phone with as many degrees of freedom as possible. Instead of using a robotic arm, Radames instead has devised a "Stewart Platform". This is a device which has a platform that can be moved across six degrees of freedom.

In this project six servos are position in such a way with a rod to the platform to allow for the required movements, and the system is controlled by a Raspberry Pi. Check out the following video for a demonstration of the platform in motion:

That's a great example of Raspberrry Pi hardware control. You can learn more about the project including platform theory and design from the project's Instructables page. And for more, we're on facebookGoogle+, and twitter - so follow us for news and product updates as well.

If you need to add external circuitry to your Pi, one option is to use our PiBreak board.It provides labelled breakout pins for all GPIOs, a large prototyping area with solder pads, and power rails for easy power connection:

Furthermore the PiBreak also includes mounting hardware to firmly attach it to your Raspberry Pi using a nut, bolt, and spacer - and is compatible with all revisions of both model A and B Raspberry Pi computers. For more information about our PiBreak board, our Getting Started guide, and to order - visit the product page.
