The latest research: how to let the robot gracefully fall?
    In a large robot contest held in June this year, millions of dollars worth of machines struggle to complete some simple tasks, such as climbing stairs and so on. In the process of completing the task, these robots have some very funny mistakes, and these mistakes have led to the robot's equipment, motors and other components of a devastating destruction.

   For these clumsy robot, is very lucky, the researchers is exploring to make robots more graceful fall. This research has become very important when robots are used in more complex environments or with mechanical legs instead of wheels.

   Researchers from Georgia Tech from the time of the fall of mankind will extend an arm or a leg to avoid their own way to be seriously injured in the way to get inspiration. Liu Karen, a computer science professor, and Ha Sehoon, who conducted the study, said: "when you fall down, you need to consume energy. When you are in contact with the ground, some of the energy is dissipated."

    Liu Sehoon and Ha Karen designed an algorithm that allows the robot to lose its balance of its own calculations should be how to twist the body to reduce the impact of the ground force. This algorithm will help the robot to create a series of contact points with the ground, in order to disperse the power of contact with the ground.

    They are a known as test algorithm of BioloidGP of small humanoid robot, and a simulation in the large robot atlas, the latter developed by the Boston power company, the company specializes in the manufacture of advanced legged robots.

    In June, the DARPA robot challenge, a lot of teams have used the Atlas robot. During the course of the game, all robots in remote control mode of operation to complete, including driving a golf cart, opened a series of doors and drill operation, a number of tasks. This event is mainly used to simulate the robot in the repair of damaged nuclear power plants will be encountered problems, of course, there are robots in human work environment may be encountered challenges.

    DeDonato Matt, the leader of the Worcester Polytechnic Institute, said that most of the participants were more focused on keeping the robot upright, rather than making a better way to fall, because each time the fall will be punished by time. He said: "the robot is becoming more and more commercialized today, the field of robotics falls needs more exploration, because it always falls down."

    Liu Karen said that in addition to research how to allow the robot to reduce the impact on the ground outside, she and her research team also on the robot in the fall to avoid harm to human way very interested in. He believes that this may involve some kind of balance, so that the robot can not fall in the direction of human.

    So far, researchers have developed methods not much because of the limitations of sensor and robot computing power. Liu Karen pointed out that their study is a good explanation for why a variety of animals, including humans, have a nervous system to control the body's response.
