Not so long ago, when we mentioned “open source,” we were nearly always talking about software. These days, open source can refer to almost anything — like this affordable DIY robot from “Cheap Arm Project.”
The Screening Room
When someone creates a new GitHub repository for a project that could help people around the world extend the reach of their limbs, I get a lump in my throat. The YouTube description of this open source hardware/software project describes the project in much better ways than I ever could.
“The video shows first design of teleoperated mobile robotic manipulator produced in the Cheap Arm Project (CHAP). It costs less than $2,000, uses easily available parts and can be assembled by anybody with basic technical skills. The manipulator can reach objects from floor-level up to shelves at a height of 170cm using a new low-cost arm design. Teleoperation is done using a tablet, smartphone or browser. The cost could be further reduced by using different servomotors. The design and assembly instructions are made available on the open-source repository GitHub, with the hope that the community will build and improve the design.
