Robotic arms haven’t been the same since Tomy stopped making the Armatron but that doesn’t mean you have to live your life without a robotic helpmate. The Fixbot Robotic hand is a DIY project that requires a bunch of time, servos, and 3D printed parts, but it’s easy to make if you have a little time. It’s part of a marketing campaign by Sugru, a self-setting moldable rubber for repairing electronics.
The video shows the Fixbot repairing things around the house (Note: Fixbot will not fix your house or car) but you can use this little guy to wave at people across the room or scratch your back for you with its gentle plastic claw.
It requires an Arduino board, 4 Hitec HS-422 servos, and a microservo. You also need access to a 3D printer. A little buffing, a little screwing, and some electronics know-how and you’re ready to rock.
