The lamp in question is a relatively inexpensive spring-balanced desk lamp that when looked at in another light has all the metalwork ready-cut for a 5 degrees of freedom robot arm when combined with 3D-printed servo holders for five servos at its joints. A particular theme in this endeavour comes from the IKEA hacking community, who take the products of the Swedish furniture store and use them for the basis of their work.Ī particularly inventive piece of IKEA hacking is a project from, a low-cost 3D-printed robot arm based on Ikea Tertial lamp. We’re used to projects that take everyday household objects and modify or enhance them into new and exciting forms that their original designers never intended. If you need a softer touch, try emulating an octopus tentacle.Ĭontinue reading “Open-Source Arm Puts Robotics Within Reach” → Posted in Robots Hacks Tagged 6-DOF, arduino mega, closed loop, closed loop control, diy robot arm, six-axis robot, Teensy 3.5 The AR3’s grippers work well, as you’ll see in the video. Did you build an AR2? The good news is that AR3 is completely backward-compatible. Check out ’ playlist of AR2 builds - people are using them for photography, welding, and serving ice cream. Between the site and the community already in place from AR2, anyone with enough time, money and determination could probably build one. He also has tutorial videos for programming and calibrating, and wrote an extremely detailed assembly manual. set up a site with the code, his control software, and all the STL files. In the demo video after the break, shows off AR3’s impressive control after a brief robotic ballet in which two AR3s move in hypnotizing unison. The motors and encoders are controlled with a Teensy 3.5, while an Arduino Mega handles I/O, the grippers, and the servos. It also auto-calibrates itself using limit switches.ĪR3 is designed to be milled from aluminium or entirely 3D printed. If something bumps the arm or it crashes, the bot will recover its previous position automatically. The biggest improvement is that AR2 had a closed-loop control system, and AR3 is open-loop. Since then he’s been improving the arm and making it more accessible for anyone who doesn’t get to play with industrial robots all day at work. In November 2017, we showed you ’s open-source 6-DOF robot arm.
