Mechanical Metamaterials Can Block Symmetry of Motion

An artist’s rendering of mechanical metamaterials. (Credit: Cockrell School of Engineering) Engineers and scientists at the University of Texas at Austin and the AMOLF institute in the Netherlands have invented mechanical metamaterials that transfer motion in one direction while blocking it in the other. The material can be thought of as a mechanical one-way shield that blocks energy from coming in but easily transmits it going out the other side. The researchers developed the mechanical materials using metamaterials, which are synthetic materials with properties that cannot be found in nature.

Magnetic Motor-Feedback Kits – A New Way to Improve Performance and Reduce Costs

Today’s motor-feedback systems generally fall into one of two categories: high performance and very expensive or low cost, but lacking performance and features.

Exo-Brake “Parachute” to Enable Safe Return for Small Spacecraft

Engineers pack the Technology Education Satellite with the Exo-Brake payload. Almost 4 square feet in cross section (0.35 square meters), the Exo-Brake is made of Mylar and is controlled by a hybrid system of mechanic struts and flexible cord. (Credit: NASA Ames/Dominic Hart) Engineers at NASA’s Ames Research Center in Moffett Field, CA have been testing its Exo-Brake technology as a simple design that promises to help bring small payloads back through Earth’s atmosphere unharmed. An Exo-Brake is a tension-based, flexible braking device resembling a cross-parachute that deploys from the rear of a satellite to increase the drag. It is a de-orbit device that replaces the more complicated rocket-based systems that would normally be employed during the de-orbit phase of re-entry.

Six-Legged Robots Move Faster with Bipod Gate

Researchers have discovered a faster and more efficient gait, never observed in nature, for six-legged robots walking on flat ground. Bio-inspired gaits, which are less efficient for robots, are used by real insects because they have adhesive pads to walk in three dimensions. (Credit: EPFL/Alain Herzog) Researchers in Lausanne, Switzerland have determined that a bipod gait is the fastest and most efficient way for six-legged robots to move on flat ground, provided they don’t have the adhesive pads used by insects to climb walls and ceilings. This suggests designers of insect-inspired robots should make a break with the nature-inspired tripod-gait paradigm.

Evaluation Standard for Robotic Research

Universal benchmarks can standardize the measurement of robotic manipulation tasks.The Yale-CMU-Berkeley (YCB) Object and Model Set provides universal benchmarks for labs specializing in robotic manipulation and prosthetics. About two years ago, Aaron Dollar, an associate professor of mechanical engineering and materials science at Yale University, came up with the benchmark idea to bring a level of specificity and universality to manipulation tasks in robotics research. He enlisted the help of two former colleagues in the robotics community, Dr. Siddhartha Srinivasa from Carnegie-Mellon University and Dr. Pieter Abbeel of the University of California, Berkeley.
