Japanese companies strive to build anti nuclear radiation robots

other companies, including Hitachi and Toshiba, have recently launched their own remote-control robots. The Fukushima nuclear power plant was damaged in the 2011 earthquake and tsunami. There are already robots working inside the nuclear power plant, but no robots are specially designed for this kind of work. A British expert says working inside a nuclear reactor is a challenge for robots

Mitsubishi's tank robot is called Meister. It is about 1.3m high and has two 7-DOF arms. It can lift up to 15kg. The robot is equipped with a variety of tools and has enhanced electronic equipment to withstand radiation

but Jeremy Pitt of Imperial College London said that it is still a challenge to successfully replace human beings with a remotely controlled machine under such difficult conditions. He said: operating in extreme environments requires extraordinary human skills, and that's right

he added: fundamentally speaking, it is not necessary to design the program of a robot to work according to a series of precise actions, but to design its program to be adaptable in an open environment. This requires the combination of the conscious reasoning mechanism of learning and the unconscious sensory mechanism

different designs

although there are several robots in the nuclear power plant, ouyangming claims that they are not designed to repair nuclear reactors. For example, the robot made by Quinatic was introduced shortly after the Fukushima disaster. Company spokesman Mark Clark said it was designed to find mines. He said that using machines not designed for this situation has always been a kind of helplessness, and better robots are needed

this operating environment in a large and complex nuclear power plant puts forward high requirements for these robots, and they have never been designed to meet these requirements. If you want to operate robots in a nuclear power plant environment full of debris and radiation 24 hours a day, it is best to design them to perform special tasks from the beginning

for example, Toshiba claims that its machines are wirelessly connected and can be operated in a high radiation environment. When the signal weakens, it will look for a better signal. Mr. Clark explained that the biggest problem for robots working in these areas is maintenance, because if maintenance is needed, it will be very difficult for humans to get close. The solution is to repair each fault of the experimental machine remotely, which is divided into mechanical type and hydraulic type according to the transmission mode, or wear heavy anti radiation clothing

if such robots start to leak hydraulic oil, they will give an alarm before failure, so that they can be repaired quickly. Other robots can get rid of or abandon their robot arms, so if they are trapped by debris, they will abandon the trapped or buried lines in the wall, so that they can be free. Most robots in nuclear power plants are powered by a new standard system connected by a drag, which covers all links such as raw and auxiliary materials, production management and product testing. This means that there is no need to replace batteries and deal with the problem of replacing fuel
