Our student team won the iCAN Original China Elite Special Award for the International Finals

On March 7th, at the 2019 Global Innovation Education Conference and the 12th iCAN Original China Classic Contest held at the Beijing National Convention Center, our students' Behavior Control Technology Based on the Conditional Reflection Principle of Animal "Robot" was from 35 The representative team stood out and won the special prize. Zhang Hongxuan selected the team to participate in the competition. This is the fourth special prize won by Zhengzhou University in the past nine years. The four special prizes are all students of our school. (The first three projects are Magic Flower, Smart Wheelchair and New Combination. Corner wall climbing robot"). In June this year, the team will represent the Chinese national team to participate in the 12th iCAN International Innovation and International Finals held in Berlin, Germany, to showcase the innovative strength and style of Chinese college students. The event will be held with the 20th World Sensors Congress together.

By putting the turtle on a "armor" with only one egg weight, it can crawl according to the instructions and reach the destination accurately. This ounds like a picture in a sci-fi movie. However, the team consisting of Wang Kaiyong (Captain) , Pei Lei of our school, Ni Xincheng of the School of Life Sciences, Zhao Shiqian of the Business School, and Jia Tongtong of the Foreign Languages Institute The "Animal Behavior Control Technology" project and turned it into reality.

Light stimulation technology to fill gaps in animal research

At the competition site, the team members had face-to-face exchanges with Dr. Aaron Chehanovo, 2004 Nobel Laureate in Chemistry, IEEE Fukuda, male general of the IEEE, and Dr. Cheng Heping, Peking University. Academician Cheng Heping praised: "This equipment is not expensive, simple to operate, harmless to animals, and very innovative!" In addition, its use of light technology to intervene in animal behavior has filled the gap in animal research.

The "magic weapon" for the control of turtle behavior is a curved "turtle helmet" with a length and width of about 10 cm and a height of about 5 cm. In order to make the Brazilian tortoise move, Wang Kaiyong and the team members used 3D printing technology to create a shell-like, telescopic black casing as the main body of the product.

In the experiment, the team members found that the Brazilian tortoise responded to the specific wavelength of light and the sound stimulation of a specific frequency. For example, they would escape in the opposite direction before the black obstruction, so they installed the ultraviolet generating device and the ultraviolet receiving at the gap of the outer casing. Equipment and WIFI camera. The pool line at the top of the black enclosure is the "core hub" for the product. Before the equipment is activated, the turtle helmet can be perfectly matched with the turtle shell by simply attaching a fixture to the top of the turtle shell. Move the remote control to make the turtle "obedient".

Through repeated trials, the participating equipment is the third generation.

"Before I was teasing the tortoise in the bedroom, I found that the tortoise had strong stress on the light. I thought it was very interesting. I silently wrote it down." Wang Kaiyong said that he usually likes to study robots, but the cost of bionic robots is too high. And the animal's nerve reflex and behavioral activities cannot be fully simulated, and the animal itself has many advantages such as high flexibility and maneuverability, so he turned his attention to living animals such as turtles.

In order to get more accurate results, team members selected the three most active Brazilian tortoises on the market, conducted thousands of light stimulation experiments on them, and observed their responses and trajectories. After drawing the conclusion, the teammates wanted to design a “turtle helmet” to control the behavior of the Brazilian tortoise.

However, although the idea is good, it is really difficult to implement: the "turtle helmet" shell is not high enough. The shading effect is not good. If the shell is too heavy, the turtle crawling speed will slow down. If the fixed area is too small, the equipment will shake left and right... In Zhang Hongxuan Under the careful guidance of the teacher and Cui Chao, the team members constantly adjusted, tried to improve and strive for excellence. “It takes at least 27 hours for 3D printing to make a shell. The construction period is short and the test period is long. This is a big test for us.” Captain Wang Kaixi said, “The first and second generation equipments are too heavy. Too big, the internal skeleton is too loose, and all are eliminated. The equipment for the competition is the third generation."

Wide application range, great prospects.

Mounting the camera on the animal's "helmet" will make it a camera that is not easily noticeable; placing control equipment on the endangered animals can help them find escape routes; and give turtles, pigeons, and mice a little bit. "Reconstruction", they can be transformed into a "pioneer scout" on the battlefield, Wang Kaixuan team's "animal behavior control technology" prospects are gratifying. Team members hope that this technology can be applied to military reconnaissance, geological exploration and other fields. The inherent advantages of animals will help humans to make greater progress in these areas.

Academician Cheng Heping is interested in the use of animal conditioning to intervene in the behavior of living animals. He also said, "I hope that you can do some in-depth research to find applications in other animals such as mice and pigeons."

Next, the team intends to further miniaturize and integrate the device to enhance concealment. Increase the waterproof function to suit the actual needs. The team will continue to improve the performance of the equipment, hoping to go to the market for further application and promotion.

In recent years, the leaders of our institute have strongly supported the students' scientific and technological innovation activities. Based on the construction of students' science and technology laboratories and guided by policy incentives, they have trained a group of top-notch innovative talents and hatched a number of high-level students' scientific and technological innovation achievements.
