Beetle-mounted camera streams insect adventures

Researchers have developed a tiny wireless camera that is light enough to be carried by live beetles.

The team at the University of Washington in the US drew inspiration from the insects to create its low-powered camera system.

Its beetle-cam can stream up to five frames per second of low-resolution, black and white footage to a nearby smartphone.

The research was published in the Science Robotics journal.

The entire camera rig weighs just 250 milligrams, which is about a tenth of the weight of a playing card.

While the sensor itself is low resolution, capturing just 160 by 120 pixel images, it is mounted on a mechanical arm that can shift from side to side.

That allows the camera to look side to side and scan the environment, just like a beetle, and capture a higher-resolution panoramic image.
