Cornell University physics researchers have made robots that can, for the first time, sense the temperature of their surroundings and react together to change it. “Little things can have a large impact,” said Itai Cohen, a leader in developing microscopic robots and a corresponding author on the study.Cornell University physics researchers have made robots that can, for the first time, sense the temperature of their surroundings and react together to change it. “Little things can have a large impact,” said Itai Cohen, a leader in developing microscopic robots and a corresponding author on the study.[#item_full_content]
