The rescue robot developed by Xi'an university student team won the award

the winning team debugged the robot at the competition site

"our robot provides a new detection robot mechanism for detection and search in narrow environment during rescue and rescue." Liuhanfei, the "difficult man-machine" team of Xi'an University of science and technology, said so. It was learned on October 28 that at the 9th China educational robot competition, the "difficult man-machine" team of Xi'an University of science and technology presented their plan and won the special prize in the competition. It turned out that nowadays, all kinds of rescue robots are emerging in endlessly, but most rescue robots focus on ultra-high load and executable mechanism. How to make the rescue robot perform its skills in small scenes is a difficult research point

original intention: make modest contributions to the rescue cause of the motherland

in this competition, under the guidance of teacher lihongyan, liuhanfei and his teammates in the low-intensity seismic fortification Zone focused on the rescue robots in small scenes that are rarely seen in the market at present. They plan to build a detection robot based on a single track actuator to solve the problems such as detection in collapsed ruins or various tunnels and tunnels, and put forward requirements for organizing this year's peak shift production. Detection worker gb/t 3923.1 (1) 997 textiles tensile properties Part 1: Determination of breaking strength and elongation at break strip method. Since June, the "difficult man-machine" team has been rooted in the laboratory without interruption. Up to the competition, their work rhythm is tense and orderly, and their life is completely centered on robot research and design

the works designed by the "difficult man-machine" team are mainly designed by modular method, which is divided into four parts: mechanical structure, motor drive, steering, lifting and control. The mechanical structure adopts self-made structure, which realizes the mobile work of the single track robot through the connection and application of structural parts. The length of the fuselage is combined according to the work needs, and the overall structure of the robot is reconstructed

in the four part design, the team has both division of labor and collaboration. For example, STM32F103 is used as the main control circuit, and the chip has 64 pins in total. After confirming which corresponding pin each module and component is connected to, various problems still occur in the actual connection. Troubleshooting is a grinding and urgent task, However, liuhanfei said, "I was very excited when I thought that our robots would have the opportunity to participate in the accident rescue. If we could make modest contributions to the rescue cause of the motherland, it would take us some time to overcome the difficulties if we wanted to make the team full of confidence in this new process."

it can effectively increase the probability of rescue and survival of trapped people

the China educational robot competition is hosted by the Chinese society of artificial intelligence. It is a major robot competition to promote educational robots into the classroom and promote the popularization and implementation of robot assisted engineering innovation and practice education courses. It attracts many colleges and universities across the country to participate every year

Liu Hanfei is full of confidence in the robot designed by his team. The detection robot based on STM32F103 control board can enter the narrow places where conventional robots or detection equipment cannot enter for search and rescue work; The image transmission of the rescue scene through the camera carried by the robot can provide reliable rescue information for the rescuers; The implementation of control and two-way communication functions can enable the trapped people to get in touch with the rescuers and increase the probability of successful rescue; By dragging small water pipes, some liquid nutrients can be transported to the hands of trapped people in time to enhance the survival probability

in the end, four months of hard work was not in vain. With highly completed design schemes and novel solutions, the reconfigurable single track detection robot of the "difficult man-machine" team won unanimous praise from the on-site judges. The robot's feasibility was highly recognized by the judges' experts and won the grand prize of the competition! From a rookie to a graduate student who can be independent, liuhanfei said that he is particularly grateful to the robot competition platform, and he will continue to uphold the spirit of fearing difficulties and being brave in innovation in the competition
