Scientists have actually established a tiny cordless camera that is light enough to be carried by live beetles.
The team at the University of Washington in the United States drew motivation from the pests to produce its low-powered cam system.
Its beetle-cam can stream as much as five frames per second of low-resolution, black and white footage to a nearby smartphone.
The research was released in the Science Robotics journal.
Images from the rig are sent to a smart device by means of Bluetooth

The cameras mechanical arm can pivot 60 degrees
The whole video camera rig weighs simply 250 milligrams, which is about a tenth of the weight of a playing card.
While the sensing unit itself is low resolution, capturing simply 160 by 120 pixel images, it is mounted on a mechanical arm that can move from side to side.
That enables the electronic camera to look side to side and scan the environment, simply like a beetle, and catch a higher-resolution panoramic image.

To conserve battery life, the scientists consisted of an accelerometer in the system, so that it only takes images when the beetle is moving.
This way, the electronic camera had the ability to operate for six hours on a full charge.
The beetles were not damaged and “lived for at least a year” after completion of the experiment.
The researchers used what they had actually discovered to produce an independent insect-sized camera robot.
The group claims it is the worlds “tiniest terrestrial, power-autonomous robotic with wireless vision”.

The small bot relocations by vibrating
Instead of wheels, the robot moves by vibrating and can take a trip about three centimetres a second.
Shyam Gollakota, senior author of the research, acknowledged that small electronic camera robotics might introduce brand-new security issues.
“As scientists we strongly think that its actually important to put things in the general public domain so people understand the threats therefore people can begin creating services to address them,” he said.
