These Cyborg Cockroaches Could Save Your Life
The injection mechanism is a small device that deploys a syringe using a spring system. That triggers a process that breaks the seal between a chamber containing citric acid and another containing baking soda. The resulting chemical reaction—basically the same one you might’ve done as a kid to make a volcano with baking soda and vinegar—creates enough carbon dioxide to push the plunger on the syringe and administer medication.
For the study, the research team remotely controlled a cockroach to travel from its starting point through three checkpoints and administer an injection to a simulated target.
The results showed that the success rate for injections made at close range—within 150 millimeters of the target—topped out at approximately 95 percent. The success rate for the entire sequence of tasks—from departure to completion of the injection—was 72 percent.
The researchers also successfully demonstrated teamwork, where one cockroach uses a camera to locate...
