TuFF technology is taking off Article by Karen B. Roberts Photo and video courtesy of Joby Aviation March 09, 2021 Uses for UD-developed material to include flying taxis Believe it or not, fighter jets, flying cars, natural gas pipelines and plastic bottles may be more alike than you think. So, whatâs the common thread? They might one day be made with TuFF â a high-performance short-fiber composite material invented at the University of Delaware that is superstrong, ultra-lightweight and virtually indestructible. It might even be the Superman of materials. Developed by researchers at UDâs Center for Composite Materials as part of a Defense Advanced Projects Agency (DARPA) Defense Sciences Office program, TuFF (Tailored Universal Feedstock for Forming) has properties equal to the very best composites used in space and aerospace applications today. And, according to CCM Director Jack ....
Darpa investigates commercial sector support for Moon manufacturing The US’s Defense Advanced Research Projects Agency (Darpa) is to survey the private sector about developing designs and materials for building large structures on the Moon. The R&D organisation, which operates within the United States Department of Defense, has announced its “Novel Orbital and Moon Manufacturing, Materials and Mass-efficient Design” (NOM4D, pronounced “NOMAD) programme. Highlighting the increasing support by commercial space companies for access to space , it notes that rockets inevitably impose limits on the payload they can deliver to orbit. “This size constraint hinders developing and deploying large-scale, dynamic space systems that can adapt to changes in their environment or mission,” says the agency. ....
DARPA Project Drives Simulation Technology for Off-Road Unmanned Vehicles DARPA’s Robotic Autonomy in Complex Environments with Resiliency - Simulation (RACER-Sim) project is seeking innovations in technologies that bridge the gap from simulation to the real world and significantly reduce the cost of off-road autonomy development. DARPA invites proposals for promising solutions that support these goals. While the past decade has seen increased use of simulation in developing field robotics, the military off-road environment is especially challenging and complex. Computers need to re-create three-dimensional surfaces, compliant soils and vegetation, and hundreds of obstacle classes. Software also needs to take into account lower fidelity or limited mapping data, unique platform-surface interactions, continuous motion planning, and no defined road networks or driving rules. In addition, modeling high speed ....
Mysterious News Briefly January 12, 2021 The construction industry is finding it difficult to match the strength of ancient Roman concrete so researchers at Lancaster University in the UK are trying carrots as a binder to improve cement hydration and make today’s concrete stronger. If only adding carrots would make the concrete see potholes better and call for repairs before we hit them. Sad and scary news from the San Diego Zoo where eight gorillas have tested positive for the coronavirus the first known cases among such primates in the United States and possibly the world. Zoo workers have been taking precautions and are safe, as are the Southern Masked Weavers, the Masked Lapwings and the Hermit Crabs. ....
