Harine Ravichandran, 16 from Chennai, India, has found from her experiments on power line conditioning that multi-level inverters can overcome power shortages when connected to a single phase circuit.
Luke Taylor, 15 from Cape Town, South Africa, has developed a platform that translates English into computer code, which in turn directs a prototype robot that receives the translation and conducts the corresponding action. For example, tell the robot to move forward and backwards, and it will do it. It can also do more complicated tasks like pouring a glass of water.
Luke suggests that these robots could be used in hospitals in South Africa, particularly in remote areas, where there are less staff to treat patients.
