Robotic hand uses artificial tendons consisting of strings


Robotic hands uses artificial tendons.

While the quest for robotic grippers with a light, yet firm touch has led to innovative approaches, such as the universal jamming gripper, it’s still hard to go past the four fingers and opposable thumb form factor honed by millions of years of evolution. While the technology is available to create a robotic hand that is both powerful and delicate, cramming it inside a compact arm is still difficult. But European researchers have done just that by using a novel string actuator to act as an artificial tendon.

Tiny Robotic Hand Has Strong Grip

Robotic Hand

Scientists have developed a pair of robotic hands that are both strong and sensitive

The tweezers can guide themselves to pick up and move individual cells without damaging them, and have a grip that can be as slight as 20 nanoNewtons of force. In fact, so advanced are the little grippers, that they can be hitched up to a microscope and, with the right software, function without human control. More below.
