Researchers predict a significant surge in the production of drones and autonomous robots by the late 2030s, estimating a tenfold increase for commercial drones and a hundredfold increase for humanoid and quadruped robots. This forecast, published in the journal Chem Circularity, highlights potential impacts on the supply chains of 18 essential raw materials used in these technologies, both in the United States and globally. The anticipated rise in demand for rare earth metals and carbon fiber could lead to supply challenges. To mitigate these risks, the researchers recommend that technology developers leverage existing capacities from other industries, particularly electric vehicles, to ensure a stable supply and avoid shortages in critical materials.
