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:
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.
High-tech spider for hazardous missions
Back when I was a teen Car Wars player, one of my great pleasures was kit-bashing toy cars together with arms and armor from tank models to make Mad Max-ish battlewagons to use in our autoduels (a friend with family in the USA used to help us blow up our cars with smuggled in firecrackers […]

I'm one of the "special guests" at this year's San Diego Comic-Con! If you're attending, I hope you'll come by and see some of my programming items, especially my spotlight interview with Cecil Castellucci (Friday, July 20, 1330h-1430h, Room 24ABC), where I'll be making an exciting announcement.
Summer’s here, which brings not only warmer weather but also the unsettling realization that the year is more than halfway over. So, for those who weren’t as productive as they would have liked during the first half of 2018, we’ve rounded up 5 skill course bundles you can start learning today to help you finish […]
It’s good to be proactive, but when it comes to preparing for an emergency situation, one of the most important items you can pack is a flashlight. After all, whatever else you include in your kit won’t be of much use if you can’t see what you’re doing. The Viper 1000-Lumen Tactical Flashlights not only […]
Chances are you took a handful of language classes in high school, and aside from a smattering of conjugations and vocabulary words, the only things you likely remember are the dry, rehearsed sentences that did little to make you speak like a true native. If you’re still hoping to learn a new language but want […]
