| Corresponding to Hondas Slogan "The Power of Dreams", Honda set itself the ambitious goal to create a two-legged walking robot by developing revolutionary new technology. |  |
|||
 |
Research began by envisioning the ideal robot form for use in human society. | |||
| The robot would need to be able to maneuver between objects in a room, be able to go up and down stairs and need to be able to walk on uneven ground. For this reason it had to have two legs, just like a person. |  |
|||
|
||||
| A two legged robot was made to walk. Walking by putting one leg before the other was successfully archieved. However, taking nearly five seconds between steps, it walked very slowly in a straight line. |  |
|||
 |
To increase walking speed, or to allow walking on uneven surfaces or slopes, fast walking must be realised | |||
|
||||
| Human walking was thoroughly researched and analysed. Based on this data a fast walking program was created, input into the robot and experiments were begun. The E2 robot achieved fast walking at a speed of 1.2 km/h a flat surface. |  |
|||
 |
The next step was realised fast, stable walking in the human living environment, especially on uneven surfaces, slopes and steps, without falling down. | |||
|
||||
| Honda investigated techniques for stabilising walking, and developed three control techniques: - Floor Reaction Control - Target ZMP Control - Foot Planting Location Control |
 |
|||
 |
Honda´s E5 robot achieved stable, two legged walking, even on steps or sloping surfaces.The next step was to attach the legs to a body and create a humanoid robot. | |||
|
||||
| P1 can turn external electrical and computer switches on and off, grab doorknobs, and pick up and carry things. Height: 1,91m; Weight: 175 kg |
 |
|||
 |
P2, the worlds first self-regulating, two-legged humanoid walking robot debuted in December, 1996. Using wireless techniques, the torso contained a computer, motor drives, battery, wireless radio, all of which were build in. Height: 1,82m ; Weight: 210 kg |
|||
| P3: In September 1997 the two-legged humanoid walking robot P3 was completed. Size and weight were reduced by changing component materials and by decentralising the control system. Its smaller size is better suited for use in the human environment. Height: 1,60m; Weihgt: 130kg |
 |
|||
|
||||
 |
Using the know-how gained from the prototypes P2 and P3, research and development began on new technology for actual use. ASIMO represents the fruition of this pursuit. Weight was reduced to 43 kg, height to 1,20 m! |
