New perovskite material shows promise alternative silicon
Silicon dominates solar energy products -- it is stable, cheap, and efficient at turning sunlight into electricity. Any new material taking on silicon must compete, and win, on those grounds. As a result of an international research collaboration have found a stable material that efficiently creates electricity - which could challenge silicon hegemony.
Field trials of raspberry harvesting robot system
University of Plymouth spinout company Fieldwork Robotics has completed initial field trials of its robot raspberry harvesting system.
Multimaterial 3D printing
Traditional robotic systems with rigid parts often pose a threat to human operators. Recently flourishing soft actuators and robots, in contrast, offer excellent adaptivity to surroundings and safe, coexisting interaction with humans. However, their competence in load-bearing tasks is undermined by the inherent low-stiffness nature of constituent materials like silicone rubbers.
