Frida stands for Friendly Robot for Industrial Dual-arm Assembly, and the whole concept is pretty interesting. ABB, which is an industrial heavyweight, has reimagined the industrial robot, which is typically a huge, heavy piece of kit that’s expensive, not particularly flexible and too dangerous to position near human workers. Instead of the typical single, powerful robot arm with multiple degrees of freedom, ABB considered how a typical human works in their workspace at an industrial task and tried to create a robot that could work like this. ABB also priortized making the robot cheaper, thus introducing robots to smaller companies that are robot-free.
Frida’s arms have almost the same extension as a small-sized person, and while their dexterity is designed to match how human joints move, it can obviously surpass human motion limits at will–no person can spin their wrist 720 degrees, at least not outside the bounds of a horrible industrial accident. It’s also lightweight and designed to be clamped to a workbench and easily moved from its station, hence the built-in handle. To make it safe, its metal body is padded, and its motor drives have limited power so that if they do accidentally encounter a squishy human they won’t cause too much damage. There’s also software-based collision detection to prevent things getting to this point. It’s smooth, with internally routed cables, so it’s easy to keep clean. And there are few “pinch points” that a curious human digit could get trapped in.
ABB has made an effort to note it doesn’t see robots like Frida stealing jobs in the future–it’s designed to work alongside people, and could be very useful when a production line process changes and a reprogrammed robot could be retrained faster than a human worker. But it’s easy to see a future in which robots like Frida drop in price and increase in intelligence to the point they actually do replace humans on production lines, since they can also work 24-hour shifts, won’t go on strike, or cause other social problems. And for industries like electronics manufacturing, where there’s a risk of being exposed to noxious chemicals, who wouldn’t prefer to see robots working in those jobs?
