robotics

Engineers have developed tiny robots that can fly and change direction without any motors or moving parts, relying instead on sound waves for propulsion and steering. The approach could open the door to new uses in medicine and micro-manufacturing, where conventional powered devices are too large or complex. Details on the research team and results remain limited.

Two friends have jointly won a gold medal at the World Robot Competition, according to a report shared on Vietnam.vn. The pair were recognised for their joint achievement at the international robotics contest. Further details about their nationality, the winning project, and the competition's location and dates have not been made available in the reporting so far.
