GoPro for beetles: scientists created a tiny backpack with a camera weighing 0.25 grams
The researchers introduced 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.
Ordinary small cameras, such as smartphones, can take high-resolution wide-angle shots, but they consume a lot of energy for shooting, so they cannot work without a 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 power consumption.

Engineers took a black and white camera weighing 250 mg with a small resolution and mounted it on a mechanical lever. This allows not only moving it, but also getting a wide-angle view with minimal energy consumption. The whole system is controlled via Bluetooth from a smartphone at a distance of up to 120 m. In addition, the built-in accelerometer activates recording only when moving, which allows the camera to work up to six hours without recharging.
During the tests, the team fixed the system on the backs of beetles, which could freely move with it, climb the slope and even climb trees.
According to the developers, such devices can help in the study of wildlife or inaccessible places. However, technology also poses new threats to privacy.
Earlier, we also reported on the development of a focusless camera with a new flat lens.
