Chip-maker Intel has revealed a collision-avoiding drone that automatically dodges obstacles in its path. The device was demoed at the CES tech show where it autonomously detected and avoided a fallen object. Intel part-owns Yuneec, the company behind the drone, and provided the device's 3D camera sensor. The RealSense technology involved uses infrared lasers to detect the distance of nearby thing
Unwanted food produces 21 million tonnes of greenhouse gas in the UK every year An experimental drone fitted with sensors is being deployed to monitor gases rising from rubbish dumps. The unmanned aircraft is being flown above Britain's 200 landfill sites to study a major source of UK emissions.
