According to the "Nikkei Industrial News" report, each of these two robots is called an "artificial skills robot." It consists of an operator, a laser pointer, a stereo vision camera, a multimedia display, etc., and is equipped with an environmental simulation system, a programming system and a job implementation management system. This "human-skilled robot" can carry out complex operations such as valve disassembly and repair. It is characterized by being able to replace people working alone under extreme conditions. The other is called a "conversation robot." Its main body is a direct-drive operating device for operations, and is equipped with systems such as a multimedia display and program controller for monitoring. This robot can use matches, alcohol lamps, mortar, milk sticks, etc. instead of humans to complete the flame reaction test. It is characterized by the ability to engage in dialogue with others and coordinate homework. When it encounters complex situations that it cannot handle, it can use its voice to ask people for advice.
