Part 5/10:
One of the prime examples of this is a RoboBee, a micro-robot inspired by nature designed to mimic the flying capabilities of insects. These robots rely on piezoelectric crystals that enable them to flap their wings, but they have notable limitations—particularly their fragility. New developments at institutions like MIT leverage soft polymers treated with carbon nanotubes to create flexible muscle-like structures that are more durable and resistant to damage, allowing these bots to continue soaring even when faced with obstacles.
