Unmanned autonomous systems (UAS) are testing the limits of people’s comfort with independent capabilities of technology — yet these technologies are also enabling more productive crops, faster and safer disaster relief, and other benefits across fields of healthcare, defense, transportation, agriculture, and security. While some among the nonscientific population might still be making up their minds about self-driving cars and other unmanned autonomous systems, industry, government, and academia are moving forward to look for more ways to improve and even save lives. In the field Among recent projects, Hands Free Hectare at Harper Adams University was developed to enable every part of the farming process to be done by robots, not humans: “Automated machines growing the first arable crop remotely, without operators in the driving seats or agronomists on the ground.” Simon Blackmore , professor and head of engineering at Harper Adams, described in an interview with SPI...
