YouCan Robotics’ OceanEye is a luxury underwater drone engineered with aquatic exploration in mind. It features an eight-motor design with omnidirectional stability and 360-degree mobility. These motors are fully sealed and saltwater corrosion resistant. It has a top speed of 6.6 feet per second and a maximum dive depth of 328 feet. The OceanEye captures images on a 4K/30 fps camera with image-stabilization technology, and offers 10 metres of visibility with its four LED high-beam spotlights. Like other underwater drones, it is connected to its surface operator via a communications tether. Users can control the drone from dry land via a smartphone, tablet or remote control, and view the feed live, while video and photos are stored on a 64GB memory card. OceanEye is powered by a 10,000 mAh battery that provides between 30 minutes and 1 hour of use. It comes with tools such as a grabber arm, water collector, water samplers, and sonar.

A new study shows that butterflies evolved an effective way of cupping and clapping their wings to generate thrust that helps them avoid dangerous predators.

Researchers at Lund University in Sweden studied the aerodynamics of butterflies in a wind tunnel. During the upward stroke, the wings cup, creating an air-filled pocket between them. When the wings then collide, the air is forced out, resulting in a backward jet that propels the butterflies forward. The downward wing beat has another function: the butterflies stay in the air and do not fall to the ground.

This theory was described by researchers almost 50 years ago, but is only now being tested on real butterflies in free flight. It was commonly thought that butterfly wings were aerodynamically inefficient, however, researchers disagree. “That the wings are cupped when butterflies clap them together, makes the wing stroke much more effective. It is an elegant mechanism that is far more advanced than we imagined.”

These findings could help improve performance and flight technology in small drones.

This drone concept from Austrian firm WiGL Design aims to give the medical industry a super-fast way to transmit everything from drugs and vitamins to blood banks and even organs! The unique design allows for vertical takeoff before transitioning into a full glide to the destination where it again drops vertically. Upon arrival, recipients can unlock the contents using a secure touchscreen.
