3 DOF Open Source Robot Arm Is Just the Beginning

Arm3-v1

[Dan Royer] of Marginally Clever had a dream. A dream to build an open-source 6 DOF robot that anyone can make! To do so, he’s been learning robotics for the past two years, and has just finished the first step — he’s designed and built an open source 3 DOF palletizing robot!

He’s based this little guy off of the commercial ABB 460 palletizing robot, which is a tried and true industrial robot. It features all laser cut parts, a few nuts and bolts, some stepper motors and an Arduino UNO for the brain. He’s released all of the design files on Thingiverse and the firmware on GitHub — yet another project we’d like to build if only we had a laser cutter!

And don’t worry, the Arduino UNO is only being used for this first prototype — he’s already started writing code for the RUMBA (Reprap Universal Mega Board with Allegro-driver) controller for revision 2.

Stick around to see it write its first greeting with a marker — Hello World!

Air hockey robot


Don’t be ashamed, we suck at air hockey too. Luckily for us, we now have a robot opponent to blame or losing streak on. Engineers at Nuvation didn’t build this air hockey playing robot, they simply adapted a standard industrial robot arm for the task. It is controlled jointly by a ColdFire processor and a 9S08 microcontroller. An array of high power LEDs and a camera are positioned over the air hockey table, which captures the position of the puck. The robot reportedly wins 90% of its games, even against solid opponents. While this is more of project to show the power of ColdFire processors, we can’t help but think it will lead to a rash of unbeatable robot opponents. We’ve already been robo-owned at foosball; what’s next?
