Evolution of Honda Humanoid Robot E0 to E3

Honda was researched into bipedal humanoid robots began in 1986. The first milestone was to develop of prototype of bipedal that could walk in a static and straight way. It was from this progress early that were able to reach the next key stage of development, which was to develop a more stable and dynamic form of walking. Coupled with this was the need to walking of master over uneven surfaces and then stairs. A torso and two arms were successfully added to complete the first truly humanoid robot in 1993.

The next was to modify the robots so that it could operate and adapt in real world environments. This development stage saw the robot’s structure and operating systems become lighter and smaller. It was also in this phase that aids of communication were introduced as well as the early intelligence stages, allowing the robot to interact and recognize with people.

Honda’s research is continuing and with this will bring further improvements, which will see ASIMO moving closer to becoming a viable and real assistant for people in our human environment.

E0 was Honda’s first robot (E means Electronics) and with this Honda took on the challenges of creating a two-legged robot that could walk. Walking by placing one leg before the other was successfully reached, and this was assisted by the application of linear actuators to its joints. However it was taking 30s between steps, it walked very slowly in straight line. To increase the speed and to allow the robot to walk on slopes or uneven surfaces, faster walking speeds need to be achieved.

On the next stages from E1 through to E3, human walking was thoroughly researched and analyzed. It was through these studies that a faster walking program was created and input into the robot. It is the history of Honda robot developments, E1 saw the introduction of a basic joint structure. E2 achieved the first dynamic walking robot, which could also go down and up stairs. E3 was able to increase the walking speed up to 4.7 km/h. it also could carry a payload of 70kg.
