Tiny solid-state LiDAR device can 3D-map a full 180-degree field of view


Researchers in South Korea have developed an ultra-small, ultra-thin LiDAR device that splits a single laser beam into 10,000 points covering an unprecedented 180-degree field of view. It's capable of 3D depth-mapping an entire hemisphere of vision in a single shot.

Autonomous cars and robots need to be able to perceive the world around them incredibly accurately if they're going to be safe and useful in real-world conditions. In humans, and other autonomous biological entities, this requires a range of different senses and some pretty extraordinary real-time data processing, and the same will likely be true for our technological offspring.

Swimming robot performs butterfly to move with unmatched speed


Scientists regularly draw ideas from the natural world in a bid to improve robotic performance, and when it comes to soft robots that swim, motion in the ocean is a rich source of inspiration. The latest creation to emerge in this space is a soft robot modeled on the manta ray that mimics butterfly stroke in humans to move through the water with unparalleled speed.

Quick soft-bodied robots move at the speed of a hair clip


In order for a soft-bodied robot to be practical, it has to be simple, light and energy-efficient, yet still reasonably quick. A newly developed mechanism fits the bill, and it's inspired by the humble hair clip.

If you've ever messed around with a hair clip, you may have noticed that it can be popped back and forth between two stable configurations – essentially concave and convex states. Very much inspired by that functionality, a team of scientists from Columbia University has developed what is known as the Hair Clip Mechanism (HCM).

NASA's COLDArm robot limb can handle seriously cool science


NASA is testing a new robotic arm that could revolutionize exoplanetary science for a reason most of us have probably never even considered: It doesn't need to be kept warm in order to work.

The Cold Operable Lunar Deployable Arm, or COLDArm, is being designed to operate on the south pole of the Moon, a focus of future lunar research and where future Artemis missions are expected to touchdown at some point this decade.
