Asimo
Honda's autonomous bipedal humanoid robot
Historical record
ASIMO (Advanced Step in Innovative Mobility) was Honda's humanoid biped robot, developed as a long-running research and development project aimed at creating a robot that could help people in everyday human environments. Over its lifetime it gained the ability to walk, run, hop, climb stairs, recognize faces and voices, and act autonomously in response to the people around it. Honda used ASIMO primarily for robotics research and public demonstrations rather than as a commercial product, and has since shifted its mobility research toward non-bipedal approaches.

Overview
ASIMO, short for Advanced Step in Innovative Mobility, was Honda's humanoid biped robot and the culmination of decades of Honda research into bipedal locomotion that began with its earlier P-series prototypes. First unveiled in 2000, ASIMO was conceived as a robot that could one day assist people within ordinary human living spaces, sized so it could reach light switches, doorknobs, and work at tables.
Unlike a typical product, ASIMO was developed as a research platform and public ambassador for Honda's robotics program. Successive generations added the ability to walk and run smoothly, climb and descend stairs, carry objects, recognize faces and voices, and ultimately behave autonomously by interpreting the movements and intentions of nearby people.
Honda has framed ASIMO as a concluded chapter of its robotics research, drawing lessons from more than two decades of demonstrations and shifting its focus toward non-bipedal mobility methods for future robots.
Key Features
- Autonomous behavior control that lets it make decisions and act based on the movements of surrounding people
- Bipedal locomotion capable of walking, running, hopping on one or two legs, and climbing stairs
- Multi-fingered hands with tactile and force sensing for manipulating objects and performing gestures
- Face and voice recognition enabling natural interaction with people
- Highly articulated body with many independent degrees of freedom across head, arms, hands, torso, and legs
