Robots

You've seen Spot run. You've seen Spot jump. You've seen Spot do cute little booty-shaking dance routines. Now, see Spot fire lethal weapons. Sword Defense Systems has presented a precision rifle for robot dogs, capable of nailing targets 1.2 km away.

Whether you think it’s cool or unnerving, robots are becoming more agile – and Caltech’s LEONARDO looks like one of the most nimble examples yet. LEO walks on two legs, jumps and flies, can balance on a slackline and even skateboard.

For decades sci-fi has been promising us helpful home robots, but progress and uptake have been slow. Amazon may have heeded the call with Astro, its new Alexa-on-wheels – and whether this future is more The Jetsons or Black Mirror is up to you.

At Tesla's AI Day presentation, Elon Musk has revealed that the company is working on its own AI-driven humanoid robot. The Tesla Bot is designed to "navigate through a world built for humans, and eliminate dangerous, repetitive, boring tasks."

Chinese electronics giant Xiaomi has unveiled the CyberDog, its first commercial quadruped robot – and its design inspired by out four-legged friends might be one that keen watchers of the space are familiar with.

For more than five years, a team has been developing and testing control software under Alphabet's X moonshot factory, aimed at making industrial robots smarter and easier to use. Now the project has branched out into a new company called Intrinsic.

The ISS is about to receive its third robotic arm, which will be capable of "walking" around the Russian segment of the orbital outpost all by itself. It will do so hand-over-hand thanks to the flexibility afforded by its seven motorized joints.

Amazon is understandably keen to make the job of deliveries easier. The latest idea is a new patent for a system where delivery vans would carry items almost to their destination, then send out and direct ground drones to do the final drop-off.

UC Berkeley engineers have created an insect robot that can scamper along quickly and turn on a dime – perhaps literally. The bot owes its fancy footwork to… well, its fancy feet, using varying voltages to alternate stickiness and make sharp turns.

Robots are great explorers, but one environment that’s tricky for them to navigate is through the ground. Now, engineers at UCSB and Georgia Tech have developed a snake-like robot that uses a range of methods to burrow through soft sand or soil.

Back in January, we covered an autonomous plastic trash collector called Clearbot that was designed to remove waste from local waterways. Now the startup behind the project has partnered with gaming titan Razer for an updated design.

MIT scientists have developed a finger-like sensor with the ability to dig into granular media like sand or gravel to get a sense of objects buried beneath the surface, which could lead to better ways of detecting and disarming land mines.
