Fraunhofer's 3D printed exploration spiders are intended for use "as an exploratory tool in environments that are too hazardous for humans, or too difficult to get to." They use hydraulic bellows to execute advanced maneuvers, including jumping:
High-tech spider for hazardous missions
With its long extremities, the spider has a range of ways to get around. Some models can even jump. This is possible using hydraulically operated bellows drives that serve as joints and keep limbs mobile. With no muscles to stretch their legs, these creatures build up high levels of body pressure that they then use to pump fluid into their limbs. Shooting fluid into the legs extends them. “We took this mobility principle and applied it to our bionic, computer-controlled lightweight robot. Its eight legs and body are also fitted with elastic drive bellows that operate pneumatically to bend and extend its artificial limbs,“ explains Dipl.-Ing. Ralf Becker, a scientist at IPA. The components required for locomotion, such as the control unit, valves and compressor pump, are located in the robot‘s body; the body can also carry various measuring devices and sensors, depending on the application at hand. Hinges interoperate with the bellows drives so that the legs can move forward and turn as needed. Diagonally opposed members move simultaneously, too. Bending the front pairs of legs pulls the robotic spider‘s body along, while stretching the rear extremities pushes it.

Checkmarx researchers including Erez Yalon have created a "rogue Alexa skill" that bypasses Amazon's security checks: it lurks silently and unkillably in the background of your Alexa, listening to all speech in range of it and transcribing it, then exfiltrating the text and audio of your speech to the attacker.
It's been ten years since the publication of my bestselling novel Little Brother; though the novel was written more than a decade ago, and though it deals with networked computers and mobile devices, it remains relevant, widely read, and widely cited even today.
Our computers are home to a myriad of files and documents, many of which contain sensitive information. While storing this data on your computer is convenient, it’s not exactly safe, and with news headlines highlighting data leaks and ransomware attacks on what seems like a daily basis, moving them to a safer location is a […]
Total versatility isn’t something you’d typically find in a telescope. While magnification tech has come a long way, most telescopes are designed to either gaze upon the stars or view the landscapes beneath them. The Omegon Maksutov Telescope MightyMak 60 lets you do both, and thanks to its compact design, you can easily incorporate some sightseeing into […]
