#437429 Insects found to use natural wing ...
A team of researchers from the University of California, the University of North Carolina at Chapel Hill and Pacific Northwest National Laboratory has found that insects use natural oscillations to stabilize their flight. In their study, published in the journal Science Robotics, the researchers used what they describe as “a type of calculus” (chronological calculus) to better understand the factors that are involved in keeping flapping winged insects aloft. Matěj Karásek, with Delft University of Technology has published a Focus piece in the same journal issue describing the work done by the team on this new effort. Continue reading
#437426 A 3D-printed tensegrity structure for ...
Tensegrity is a design principle that has often been applied by artists, architects and engineers to build a wide range of structures, including sculptures, frames and buildings. This principle essentially describes the dynamics that occur when a structure maintains its stability via a pervasive tensional force. Continue reading
#437418 Researchers develop biomimetic hand ...
In the current issue of Science Robotics, researchers from Istituto Italiano di Tecnologia (IIT- Italian Institute of Technology) and Centro Protesi INAIL in Italy reported on their ability to replicate the key biological properties of the human hand: natural synergistic and adaptable movement, biomimetic levels of force and speed, high anthropomorphism and grasp robustness. Developed by a collaborative of researchers, orthopaedists, industrial designers and patients, the prostetic hand called Hannes is able to restore over 90% of functionality to people with upper-limb amputations.
