This 3-D Printed Robot Could Secure the Ports Of The Future

Transport by sea has been a favorite of smugglers for centuries - it's hard to patrol an entire coastline, and it's easier to move a ton of stuff by sea than by land. In the future, though, getting your contraband through a port might be made exponentially more difficult by this tiny, ultrasound-packing submersible robot.

Designed by a MIT grad student and her prof, the robot, which is a little smaller than a football, uses ultrasound to inspect ships, looking for false hulls and prop shafts that smugglers often use to hide stuff from regular, human-powered inspections. The robot uses a unique pump-powered propulsion system that leaves no wake, so boats wouldn't have any idea that they're being inspected, either.

Best of all for port officials and their bean-counters, the robots are easy to make — most of the structural components were 3-D printed in a lab — and Sampriti Bhattacharyya, the grad student responsible for the project, reckons they could be manufactured for around $600 a pop. [MIT News]
