Have you ever struggled to carry groceries or a large stack of books and just wished you had an extra set of hands? Robotics researchers in Japan have invented mechanical limbs that could allow you to do four things at once. These extra arms are controlled by motion sensors placed around your knees and on your feet. This extra pair of arms takes a complex sequence of movements to operate. For example, to grasp, a wearer has to curl their toes, but to move the arms from left to right, they rotate their feet.
To make the arms customizable, the hand pieces can be switched out to hold a tool. At present, the arms can only be used while sitting down due to the complexity of controlling them. However, for occupations that require holding tools or finite motor skills, these arms could certainly lend a hand.
The researchers behind these robotic arms said that this prototype is one way to explore how we can edit the design of our bodies. Do you agree? Tell us in the ongoing discussion on Vialogues.
Excerpts from the discussion
@00:16 Claude.Bosse: These arms seem very complicated to use. However, I'm not sure if there would be an easier solution to control them. It is still an interesting concept despite their complexity.
@00:58 CaitlinDavey: The concept of editing our bodies is interesting. I think as technology evolves it can be increasingly put to use in extending our physical capacities.
