The ultra-light wireless camera is installed on the live beetle, the protagonist of #Cienciaalobestia, which can capture first-person images of the insect world in a small area. This technology that can record continuously for two hours can be applied to expand the horizons of navigation and communications.

In their research, published in journals Scientific robot, A researcher at the University of Washington Turn to wireless camera It can also be installed on top of insects, giving them a chance to observe from the perspective of a Marvel superhero.
He said: “We have created a low-power, low-weight wireless camera system that can capture first-person images of what is happening with live insects, or create vision for small robots.” Shyam gollakota, Associate Professor of American University, the main author of the study.
Camera to transfer video to Cell phone It is located on a robotic arm that can rotate 60 degrees at a speed of 1 to 5 images per second. In this way, you can obtain high-resolution panoramic shots or track moving objects with minimal energy consumption.
To prove the versatility of the system (weighing about 250 mg), the research team installed it on living beetle and insect-sized robots. “Vision is very important for communication and navigation, but it is extremely difficult to do so on such a small scale. Gollakota emphasized that so far, wireless vision is impossible for small robots or insects.

Reduce battery usage
One of the main problems when using small cameras, such as those used in next-generation mobile phones, is that they use a lot of features to capture high-resolution and wide-angle photos. Experts believe that this is not the case in terms of the size of the insects.
Although the camera is very light, battery They need to support them so that the entire system is too large and heavy that insects or insect-sized robots cannot carry them. In order to solve this setback, scientists have been inspired by nature, especially flies, which can only be viewed in high resolution when they are interested, thus saving energy consumption. Visual processing.
To mimic the eyesight of animals, the researchers used a small, low-power black and white camera that can scan the field of view with the help of a robotic arm. When a high voltage is applied to the device, this action will move, which will cause the material to bend and move the camera to the desired position.
Unless the researcher applies more force, the arm will remain at this angle for approximately one minute before returning to its original position. He said: “The advantage of a mobile camera is that you can have a wide-angle view of what is happening without consuming a lot of power.” Vikram Iyer, A doctoral student in electrical and computer engineering, and a co-author of the paper.
“We can track moving objects without having to spend energy to move the complete robot. The resolution of these images is also higher than when we use a wide-angle lens, which will create an image with the same number of pixels and be larger Divide in the area of the project.” He continued.
The camera and arm can be controlled via a mobile phone via Bluetooth, and the maximum distance is 120 meters. After installing it on insects accustomed to carrying similar loads, the scientists ensured that they could still move correctly when carrying the mechanism. They did it to perfection on gravel, trees or slopes. After the experiment, these insects survived for at least one year.
Depending on the activity level of the beetle, scientists can record for six hours or more using imaging accelerometers. Without this system, the recording will continue for about two hours before draining the battery.
With this system, the team also designed The world’s smallest autonomous ground robot with wireless vision. This insect-sized robot uses vibration to move and consumes almost the same power as a low-power Bluetooth radio. The next step for scientists will be to use solar energy to improve batteries.
