The hottest new Dutch robot can walk upright like

  • Detail

According to foreign media reports, Dutch scientists recently said that they have successfully developed a new robot. What is different is that it is expected that this robot can walk upright like human beings, and its walking posture and the zigzag distance of 180 ° each step are almost the same as human beings. Teaching robots to stand up and walk is a very complicated thing. Walking robots appeared in July of the 20th century. Only enterprises that constantly accept these challenges can take the initiative. In the 1990s, their application fields can be roughly divided into two categories. The first category comes from the industrial robot industry, where all activities are carried out according to fixed procedures. Its main limitations are that Dow's cost is too high, energy consumption is too large, and flexibility is not high enough. In the field of designing walking robots based on human walking, Delft University of technology in the Netherlands has always been in a pioneer position, and its application strategy is more flexible and energy-saving human walking. Daan hobran, a doctoral student at Delft University of technology, demonstrated for the first time that "falling forward" is a behavior of adjusting balance, and robots can achieve high energy efficiency and high stability at the same time. His breakthrough achievement is that he invented an appropriate method to effectively measure the stability of human walking for the first time, because the traditional view believes that "falling forward" is an unstable movement. Next, he built a new robot "frem" and used it to show improved performance. "Frem" is composed of seven motors and one balancing part, which maintains a high level of stable balance under the control of many algorithms. For example, "frem" can use the information provided by the balancing machine to separate the feet a little far away to prevent possible falls. Hobran said that "frem" is the most advanced walking robot in the world, at least in the field of robots using human walking as the starting principle. Researchers used walking process modeling to create a more natural two legged robot

an in-depth understanding of the walking process will help people solve many walking difficulties through improved diagnosis, training and rehabilitation equipment. Delft University in the Netherlands is working with sports scientists from the Free University of Amsterdam to study this field. Hobran took the ankle as an example: the ankle is a type of spring, which represents the highest level of elasticity. Therefore, hobran's research on the ankle of "frem" provides sports scientists with a further understanding of the walking process. In previous experiments, this robot will always fall down when walking. It will lean forward slightly when walking upright, and its pace will be shorter. The key part of this robot is its "brain". Its infrared eye is connected with the control circuit, which will guide it to change its footwork when necessary. Previous studies have shown that the dynamic control system in the human body includes multiple levels, and the interaction between muscle and spinal cord mainly depends on itself, until the brain is required to carry out a higher level of control. This relationship can explain why some paralyzed patients can move their legs when treading bicycles, but they can't stand up and walk. This is also the core of their research. He also pointed out that studying robots to further understand how different parts of the human body cooperate with each other when walking plays a substantive role in improving human health care. It can not only enable people to design better prosthetic limb repair methods, but also help clinical experts and patients work together to treat patients' spinal cord and other serious diseases and restore their motor ability. Dutch scientists said that their research goal is not only to promote robot technology, but also to further understand walking mechanics, and then apply it to human prosthetics and prosthetics, and even improve sports performance. At present, many walking robots of different designs have been built in the laboratory, including a robot model with flexible knees, which can accurately simulate human walking, and its energy consumption per unit weight and distance is comparable to that of human walkers
