65438+ 10/8 news, according to the official account of wechat, Shanghai jiaotong university, I believe that most people have never experienced it, such as flexible obstacle avoidance, sliding side by side with robots through the flag gate, and human-computer interaction. Recently, the hexapod ski robot designed and developed by Shanghai Jiaotong University has completed the primary track, intermediate track and the same skiing experiment as human beings in Shenyang, and passed the tests of stability control, intelligent perception, planning and decision-making. Under the call of "Winter Olympics in Science and Technology", this ski robot was developed by a biped robot research team composed of Professor Gao Feng of Shanghai Jiaotong University, School of Mechanical and Power Engineering of Shanghai Jiaotong University and School of Electronic Information and Electrical Engineering, and was supported by the National Key R&D Plan "Winter Olympics in Science and Technology" of the Ministry of Science and Technology.

In this test, the ski robot glides on a 400-meter-long intermediate snow trail with a slope of 18 degrees at a speed exceeding10m/s. By using intelligent sensing, braking control and other technologies, the experimental subjects such as robot running, turning, path planning, obstacle avoidance and human-computer interaction have been completed. Besides being flexible and graceful, it can also be controlled by wireless remote human-computer interaction.

Not only can you ski at high speed, but you can also avoid crowds and plan the best route yourself. The experiments of ski robot in primary and intermediate snow trails show that it has agile turning and braking ability, as well as strong independent perception and planning ability. It can slide at high speed in the snowy plain, make sharp turns when encountering obstacles, maintain a vigorous skiing posture, complete the task of "crossing the flag gate" in alpine skiing during the sliding process, realize good speed and direction control, and have the functions of sliding, emergency stop, obstacle avoidance and pole winding.

It is understood that this skiing robot developed by the biped robot team of Shanghai Jiaotong University is a six-legged robot, which uses double-board skiing. The four legs in the middle are divided into two groups, each leg is fixed on the snowboard to control the position and posture of the snowboard, and the two legs on both sides are respectively equipped with ski poles to imitate people and realize the function of luminous sticks. Each snowboard has five degrees of freedom, and the functions of speed control, turning and braking can be realized by controlling the attitude of the snowboard.

In this test ski resort, the hexapod ski robot has completed the safety control of high-speed skiing and obstacle avoidance in primary and intermediate ski resorts, and its sliding speed, turning skills, obstacle avoidance ability, stability, safety and reliability have all achieved good results.

The ski robot tested this time was independently developed by Shanghai Jiaotong University. After many scientific researches, the research team made innovative breakthroughs in the design of key algorithms such as robot performance control and perception planning, and independently completed the research and development of key core technologies such as mechanism design, system framework, stability control, intelligent perception and independent planning. Finally, the ski robot integrates human-computer interaction, environmental perception, trajectory planning, intelligent decision-making and stability control.

In the future, robots will also become an important participant in the ice and snow movement, giving full play to scientific and technological advantages, patrolling and carrying out rescue in mountains and ice and snow environments, helping people avoid risks and creating a comfortable and safe ice and snow experience environment.
