RMIT researchers have used lobster-inspired spiral shapes to increase the strength of 3D printed concrete structures.Natural materials like lobster exoskeletons had “evolved into high-performance structures over millions of years” according to lead researcher Dr Jonathan Tran."...lobster shells are naturally strong and naturally curved, we know this could help us deliver stronger concrete shapes like arches and flowing or twisted structures.”The team's work, published in 3D Printing and Additive Manufacturing, favourably compared these “helicoidal patterns" against other patterns. The most commonly-used 3DP build method is lines laid down on top of each other in parallel. More: https://www
Using computer vision and machine learning, AMP Robotics has designed an intelligent three-handed robot that can analyse and sort 80 items of recycling per minute using suction cups — a rate that is twice as fast as human sorters.
By speeding up the process of sorting recyclable materials, AMP Robotics hopes to increase the total amount of materials that can be effectively recycled and reused, in turn, savings tons of emissions that these otherwise missed materials would accrue in landfills.
