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.
The late, lamented Scottish writer Iain Banks (previously) was several kinds of writer, but one of his main claims to fame is his role in developing the idea of fully automated luxury communism, in his beloved Culture novels, a series of wildly original space operas about a post-singularity, post-scarcity cooperative galactic civilization devoted to games, […]
Connecting voting machines to the internet is a terrible idea: the machines are already notoriously insecure, and once they're online, anyone, anywhere in the world becomes a potential attacker.
Yasukuni Notomi ("a writer who has covered the world of stationery for many years") provides an introduction to the creative explosion in Japanese scissor-design, beginning with the "Pencut," a scissor that fits in a normal pencil-case, with retractable elastic loops for your fingers and full-length blades so you don't sacrifice power for portability.
Many of us enjoy the aesthetic of vintage electronics, but trying to use most hardware from the 1950’s isn’t necessarily practical. This is especially true where speakers are concerned. While most of us can appreciate the old-school feel of retro speakers, they have a hard time matching the convenience and power delivered by today’s Bluetooth speakers. […]
Python is one of the most popular and versatile programming languages used by developers today, making it an ideal first choice for those looking to kickstart a career in programming. While you could go back to school or sign up for a pricey coding bootcamp, you can learn the essentials of coding with Python at […]
Going back to school isn’t necessarily an option for everyone. Between the time commitments and steep tuition rates, there are obstacles aplenty as far as furthering education is concerned. However, that’s not to say it’s impossible to learn new skills. Excel with Business lets users access thousands of hours of online learning in Microsoft, business, technology, […]
