Scientists Turn Cockroaches into Tiny Rescue Robots

Australian researchers put cameras and tiny drug-injecting devices on large cockroaches, creating remote-controlled "paraborgs." In early tests, they landed injections accurately 95% of the time close up and completed the full trip-and-inject task 72% of the time. The goal: reach people trapped in rubble or caves where rescuers cannot safely go. Swarm use is five to ten years away.
