Inspired by the biomechanics of the manta ray, researchers at North Carolina State University have developed an energy-efficient soft robot that can swim more than four times faster than previous swimming soft robots. The robots are called “butterfly bots,” because their swimming motion resembles the way a person’s arms move when they are swimming the butterfly stroke.
“To date, swimming soft robots have not been able to swim faster than one body length per second, but marine animals – such as manta rays – are able to swim much faster, and much more efficiently,” says Jie Yin, corresponding author of a paper on the work and an associate professor of mechanical and aerospace engineering at NC State. “We wanted to draw on the biomechanics of these animals to see if we could develop faster, more energy-efficient soft robots. The prototypes we’ve developed work exceptionally well.”

Experimental Wearable Pops Its Top to Send Drowning Alerts
While lifeguards serve a vital purpose, it can sometimes be difficult for them to keep an eye on all the swimmers, all the time. An experimental new device has been designed to help, by sending an alert if its wearer is drowning.
Currently in rather chunky prototype form, the wrist-worn gadget is being developed by a team at Australia’s Macquarie University. It’s called APPTRAKK, and it incorporates sensors that monitor the wearer’s heart rate, blood oxygen saturation, and movement patterns, along with the depth at which it’s currently located and the amount of time that it’s been there.
All of this data is continually processed by an AI-based onboard operating system, which determines if the combined readings indicate that the person may be drowning.
If such proves to be the case, a Wi-Fi transmitter module on the device pops loose and floats to the surface. It then transmits a signal to an app on the lifeguard’s paired smartphone or tablet, which both sounds an alarm and displays the swimmer’s location in the pool. Sending that signal from the main submerged device isn’t likely to work, as radio waves don’t travel well through the water.
