Jeff Bezos demonstrated a pair of remote-controlled robotic hands at Amazon's robotics conference this week.

He was able to perform surprisingly dexterous tasks, like stacking cups.

When asked if he could solve a Rubik's cube with the robotic hands, Bezos said he couldn't do it even with his regular human hands.

The robotic hands are designed to not only imitate the movements of the person operating them but provide haptic feedback, transmitting the feeling of touch.

Jeff Bezos took control of a pair of giant remote-controlled robot hands on Wednesday at Amazon's re:MARS robotics conference in Las Vegas.

The GeekWire journalist Alan Boyle tweeted a video of the tech billionaire using the hands to stack cups and pass a ball from one hand to the other with impressive delicacy.

After being passed a Rubik's cube, Bezos responded, "No thank you, I can't even do that with my hands."

The hands don't just mirror the movement of the person wearing the gloves — they're designed to transmit the feeling of touch, known as haptic or tactile feedback.

Here's another video from one of the companies behind the robot hands.

Bezos described the feedback as "tremendous" and said that using the hands felt "weirdly natural."

The robot was an exhibit by three companies: Shadow Robot, HaptX, and SynTouch.

Shadow Robot specializes in building dexterous robotic hands and has partnered with OpenAI, the artificial-intelligence research organization cofounded by Tesla CEO Elon Musk. HaptX develops technology to give people the sensation of touch for remotely operated robotics, as well as virtual reality. SynTouch is developing robots with a sense of touch.

A HaptX spokesman told Business Insider the gloves relayed the feeling of touch using 130 tactile "actuators," inflating and deflating up to 2 millimeters to simulate touch. He added that the gloves have an "exoskeleton" outside the fingers to simulate resistive force.
