Honda was investigated in two-legged humanoid robots began in 1986. The first milestone was the development of prototype biped could walk in a static mode and rectum. It was from this early progress that could reach the next key stage of development, which was to develop a more stable and dynamic way. Added to this was the domain need to walk on uneven surfaces and stairs then. A torso and arms are added two to successfully complete the first truly humanoid robot in 1993.

The next step was to modify the robot so it can function and adapt to real-world environments. This stage of development saw the robot structure and operating systems become lighter and smaller. It was also at this stage that communication aids are introduced, and the early stages of intelligence, which enables the robot to recognize and interact with people.

Honda research is ongoing and this will bring further improvements, which will see ASIMO move closer to becoming a viable and real wizard to the people of our human environment.

E0 is the first robot of Honda (E stands Electronics) and the Honda took the challenge to create a two-legged robot that can walk. Walking through the placement of a leg before the other was successfully achieved, and this was assisted by the application of the linear actuators of the joints. However, it takes 30 years between the steps, walking very slowly in a straight line. To increase speed and allow the robot to walk on slopes or uneven surfaces, walking faster be achieved.

In the next stages of E1 to E3 a walking human was thoroughly researched and analyzed. It was through these studies that a faster walking program was created and the entry into the robot. It is the story of the evolution of the Honda robot; E1 saw the introduction of a common base structure. E2 achieved first dynamic walking robot that could also go up and down stairs. E3 was able to increase the running speed of up to 4.7 km / h. also could carry a payload of 70 kg.
