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.

The Perfect Gift For the Physicist Who Thinks In Ten Dimensions

theoretical physics object 4321
Calabi-Yau Manifold Crystal
Holiday shopping can be tough. Holiday shopping for that special someone can be tougher—especially if that someone happens to be a theoretical physicist. Luckily, for the brainiac who has everything there’s this beautiful Calabi-Yau Manifold crystal.
But what is it, you ask? Why, put simply, it’s a great representation of something we primitive humans will never be able to observe directly:

According to string theory, space-time is not four-dimensional as you might expect, but actually 10-dimensional. The extra six dimensions are believed to be compactified or rolled up into such a small space that they are unobservable at human scales of sight….
