Scientists from the USA have presented a very lightweight camera that can be mounted on beetles. They will help researchers study insect life in more detail.
The researchers have developed a tiny wireless camera that’s so lightweight that it can be mounted on insects. The team at the University of Washington in the United States was inspired by insect organisms to develop the device.
Such a camera can transmit up to five low-resolution black and white frames per second to the researchers’ smartphone. The results of the experiments were published in the journal Scientific Robotics. This device weighs just 250 milligrams.
The camera sensor has a low resolution, it can shoot a picture measuring only 160 by 120 pixels. At the same time, it is mounted on a mechanical manipulator that can rotate from side to side. This will allow researchers to scan the environment and take higher-resolution panoramic images.
To save battery power, the researchers included a system in it that takes pictures only when the beetle moves. Therefore, the camera can operate for six hours on a full charge. Beetles do not suffer from the camera and, on average, live as long as other insects.
The team claims it is “the world’s smallest ground-based, non-volatile, wireless-vision robot.” This device will allow researchers to obtain information about insect life that they would not have received from observations.
