According to the "Nikkei Business News" reported on September 9, the development of robots that can enter the places where human beings are difficult to get involved and the purpose of disaster relief is on the rise. For example, there are four legs, a robot that can jump on the ground like a cat using a spring, and a robot that can move forward in a curved pipe like a snake. In order to make these robots practical, relevant preparations are also making progress.
The impact force of the robot's foot is accumulated on the spring, and then moves flexibly like a cat. The 4-foot robot developed by Professor Akio and Others of the University of Electro-Communications in Japan strives to use obstacles such as jumping rubble at the disaster site. Expand your search. During the development process, the professor analyzes the movements with the image of the cat walking, and replaces the function of the muscle by combining springs and motors.
The robot can move at a speed of about 3.5 kilometers per hour. In the future, we will work hard on the movement of the legs to further accelerate the speed. I hope that within 3 years, I can skip the height of 1 meter.
In June, the Defense Advanced Research Projects Agency (DARPA) of the US Department of Defense held a disaster relief robot competition in California. Five teams from Japan, including the University of Tokyo and the Industrial Technology Research Institute, participated in the competition. The robots developed by each team challenged eight topics such as vehicle driving and wall damage. The Korean team eventually won. Worldwide, robot development for disaster relief is making continuous progress.
However, technologies that have been developed very quickly cannot be put to practical use without an empirical laboratory. In order to speed up the practical use, Fukushima Prefecture, Japan, established the "Fukushima Bintong Robot Evidence Area" with the Ministry of Economy, Trade and Industry and the Cabinet Office. Bridges, tunnels, dams and rivers in Fukushima Prefecture will be provided as an empirical test site.
The demonstration area has been open to recruiting trials since April, and as of the end of May, 28 robots from 12 companies have applied for participation. Recently decided to use MTS & Planning (Fukushima City) as the first company to conduct empirical tests. The company will carry out a handling test using a multi-rotor aircraft at the Shimoda Industrial Land in Nansuma City, Fukushima Prefecture. Fukushima Prefecture and other companies intend to use this area as an empirical site for more robots.
Supporting the robot is a variety of sensor technologies equivalent to human eyes and ears. Beiyang Electric, Osaka, Japan, developed a three-dimensional ranging sensor that can grasp the three-dimensional structure of surrounding terrain and obstacles. By using a combination of motors and self-developed mirrors, the laser of the range can be passed horizontally and vertically. Technology is also being developed to develop stable robots.
In the maintenance of disasters such as the collapse of the bridge body, the use of robots is becoming more widespread. HiBot, a startup company established by the Tokyo Institute of Technology, has developed a robot that can check the infrastructure of pipes and their aging. These robots, which can be like snakes, are completely different from ordinary robots and will be highly regarded.
