Researchers presented a miniature robotic backpack with a controlled wireless camera that can transmit video at a speed of 1 to 5 frames per second and rotate 60 degrees.
Conventional small cameras such as those found in smartphones can do wide-angle high resolution shots, but consume a lot of power to shoot, so cannot operate without massive battery.
A team of scientists from the University of Washington decided to use the principles of insect vision to achieve high enough quality with minimal energy consumption..
The engineers took a 250 mg black and white camera with low resolution and fixed it to a mechanical arm. This allows not only to move it, but also to obtain a wide-angle view with minimal energy consumption. The entire system is controlled via Bluetooth from a smartphone at a distance of up to 120 m.In addition, the built-in accelerometer only activates recording when moving, which allows the camera to work for up to six hours on a single charge.
During the tests, the team secured the system on the backs of beetles that could move freely with her, climb the slope and even climb trees.
According to the developers, such devices can help in the study of wildlife or hard-to-reach places..
However, technology is also linked to emerging privacy threats..
We also previously reported on the development of a focusless camera with a new flat lens..
