Kinect-controlled delta robot has a magnetic personality


[Malte] is a loyal Hackaday reader and neurobiology PhD candidate with a keen interest in hobby robotics – definitely our kind of guy! He wrote in to share a project he has been working on in his spare time, a Kinect-controlled delta robot (Google translation).

Deltares, as it is called, is pretty straightforward as far as delta robots are concerned. It uses three servos to actuate the arms, which are controlled by an AVR micro running BASCOM. The AVR gets its coordinate data from his computer via a serial connection after it has been captured by the Kinect. [Malte] opted to use Microsoft’s official SDK for the project, processing the Kinect skeletal data using a small C# application he wrote.

The end result is pretty neat as you can see in the pair of videos below. In the first video, [Malte] uses Deltares as a plotter, drawing a crude face on a piece of paper with a marker. In the second, he commands Deltares with his right hand, using his left to activate the magnetic solenoid to pick up the steel spheres.

It looks pretty cool to us, and we’d love to see what sorts of things he puts together if he ever ends up making robotics his career rather than a hobby.

ArduDelta would make a great pick and place machine

[Bogdan] sent in a great build of a delta robot he originally posted on the Arduino forum, but he didn’t receive much feedback there. We think a build like this deserves a lot more credit.

After working for 7 months on his robot, [Bogdan] has a pretty stable (and very classy) platform made out of wood. The platform and arms in delta robots are usually extremely light to reduce the inertia of the tool so [Bodan] crafted these out of carbon fiber tubes and plexiglas. Everything is controlled by an Arduino Mega2560 encased in a plexiglas enclosure with a 20×4 LCD, status LEDs, and an infrared receiver.
