Franka, a $10,000 robot arm that can build itself over and over

Robots building robots!

Franka Emika, a new product coming in 2017 to the burgeoning field of collaborative robots, is a robot arm pitched to be easily programmable out of the box, unable to kill anyone, and capable of building more copies of itself. It is also set to vastly undercut its competition on price, costing about $10,500 (€9,900). Competitors start around $30,000.

The robot is safe because it’s torque-controlled, according to IEEE Spectrum, which means that it uses sensors to measure strain on its seven joints. The safety feature works because the software controlling the arm contains a comprehensive model of how the robot should move, and how much natural strain the joints should feel. If the measured strain deviates from what the model says it should be, the arm immediately stops. Factory robots today largely don’t have this functionality, meaning they wouldn’t know if there crushing the human next to them. For this reason, many factory robots work in cages.
