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.

Update: Open source pick-and-place

[Tim’s] been busy moving his pick-and-place build toward completion. We looked in on the first version of the vacuum head back in October. Since then he’s ditched the camera enclosure which allows for more light and better mounting. The tip has been replaced by one from a pair of vacuum tweezers, and the whole thing is now mounted on a diy CNC machine. The video after the break shows it picking up that IC and moving it around the table. Looks like the part rotation feature is very accurate.

He mentions that the CNC he’s using is quite slow. We hope he checks out this printable Delta robot; hardware that is often used with pick and place machines.

Home built Delta Robot

Theres an interesting thread going on at RoboterNetz.de (translated) about building delta robots. For those who haven’t seen delta robots before, be sure to check the video after the break for some really impressive agility displays. A delta robot usually has 3 arms connected to a single point at the end. This configuration allows the end point to maintain its “level” while the whole unit is moved, usually very quickly. There are a few people building them in this forum. The one pictured above is [Asurofilmchen]’s version, but you should also check out [Radbruch]’s posts of a robot made by [Jamison].
