   After nearly two months of experimentation, the long-range polar roaming robot autonomously developed by the State Key Laboratory of Robotics of the Shenyang Institute of Automation, Chinese Academy of Sciences, passed the "physical quality" test in the Antarctic, the first time in the inland ice sheet. The area completed 30 km of autonomous walking.


   Can work at minus 40°C

   The long-range ice cap roaming robot resembles an orange track-type sport utility vehicle with a weight of approximately 0.5 tons. It consists of a tracked mobile system, an autonomous driving system, a telecommunication system, and a payload system. It is also equipped with an autonomous driving system that can operate normally at a low temperature of minus 40°C.


   Shu Chunguang and Chen Cheng from Shenyang Institute of Automation are the site executors of the fieldwork and application research project for polar robots. From December 9th to February 5th this year, they have assembled near Zhongshan Station and inland. In the ice cover area near the ground, the robot was tested for the performance of the moving mechanism, the ice-sweeping radar loading test, and the long-distance autonomous walking test, and the expected test results were achieved.


   Bu Chunguang said that the Antarctic ice sheet environment is a complex field environment. The biggest difficulty in this experiment is how robots represent and understand complex environments and make rational decisions in complex environments.


   Specifically, in the test area on the Antarctic ice sheet, ice cracks, snow-melting holes, artificial obstacles such as containers and oil tanks are scattered. These are obstacles that robots need to identify and avoid.


   Want to study 60,000 square kilometers of ice shelf


   The crawler mechanism of the robot is equivalent to the robot's foot. The sensor system is equivalent to the robot's eyes. The autonomous control computer system is equivalent to the robot's brain. Each unit coordinates the work to complete the test task.


   Now that the robot has feet, but the eyes are not sensitive enough, the brain needs to be further strengthened. "Bu Chunguang said that after returning home, the system design of the robot will be improved and applied to the Antarctic scientific research project.


   It is reported that the ultimate goal of the long-range polar roaming robot is to be able to conduct an independent scientific investigation of the Emory Ice Shelf in an area of approximately 60,000 square kilometers. The 30-kilometer self-propelled walk in the inland ice-covered area is just the beginning.


   After the researchers return home, they will continue to improve and optimize the robot design based on the data obtained from this experiment. As a kind of intelligent equipment, robots can extend the eyes and hands and feet of scientists to achieve functions such as roaming, observation, and sampling. They are important for large-scale, deep-level polar exploration, and can also avoid extreme polar weather and natural conditions. The risk to the examinee from the conditions.
