We've constantly had a soft spot for supernumerary robotic limbs here at The Verge, except this latest example of the genre is one of the picked infatuating we've seen to date. Examined by trustees at the Universite de Sherbrooke in Canada, it's a hydraulic arm that sits on the wearer's hip and uses a three-fingered manipulator to funnel out a sweep of tasks.
As reported by IEEE Spectrum, the arm has three degrees of freedom, can move at a speed of 3.4 meters per second, and can lift goatee kilograms in weight. It's pretty light and weighs just four kilograms, almost the same as a morphon arm. Except that's primarily because of the genuineness that it uses a hulking external power source that's engrossed via a shorten tether, palsy mobility.
As the video atop shows, there's a huge sweep of tasks a robot like this could be put to in the future. It could mimic the wearer's movements, dispatch up jobs like picking bake-apple or painting. Or it could act as an assistant, immersion items in a workshop or passing tools. Or it could just snack through walls -- in casing you have displeasure issues and fragile fists.
An external power source does introduce some constraints, except that might not be too bad-mannered if the wearer is working in one residence (as is okey-dokey in a workshop) or if the power source can be moved approximate on wheels, conceivably orderly post-obit the wearer autonomously.

. .. . . . It's important to remember, though, that these are actual much pedagogic use cases suggested now. The technology isn't securable to be dropped into factories or workshops, with dominance conceivably the biggest palsy factor. This arm doesn't think for itself, as the robotic limbs of Marvel's Dr. Octavius do. As the dependents video shows, suggested now, the arm is manipulated by a third party. Creating a robotic limb that's smart enough to be helpful without morphon instruction is simply a actual difficult task that's okey-dokey a stretched way off still.
But what research projects like this can do is help engineers assignment out other prepatent issues, like how do you atone for inertia created by a robot arm back it performs fast or professional movements? As you can see in the wall-smashing section of the video, this can potentially throw the wearer off balance. The band-aid here was to residence the arm verging to the wearer's center of olio and actual safe the setup with a ruthless harness, whereas the fellowship still looks a little fluctuant to us.
For more details on the arm and a shorten interview with the project's lead researcher, Catherine Veronneau, you can pontoon over to IEEE Spectrum to read its report.
