The E-series was a collection of successive humanoid robots created by the Honda Motor Company between 1986 and 1991. The robots were only experimental, and later evolved into the Honda P series, with Honda eventually amassing the knowledge and experience necessary to create Honda's advanced humanoid robot: ASIMO.

E0, unveiled in 1986, was the very first robot. It walked in a straight line on two feet, in a manner resembling human locomotion, taking around 5 seconds to complete a single step. Quickly engineers realised that in order to walk up slopes, the robot would need to travel faster.[1] The model has 6 degrees of freedom: 1 in each groin, 1 in each knee and 1 in each ankle.

E1, unveiled in 1987, was larger than the first and walked at 0.25 km/h.[2] Since the model, the E-series robots have 12 degrees of freedom: 3 in each groin, 1 in each knee and 2 in each ankle.

E2, unveiled in 1989, could travel at 1.2km/h, through the development of 'dynamic movement.'[2]

E3, unveiled in 1991, travelled at 3km/h, the average speed of a walking human.[2]

E4, unveiled in 1991, lengthened the knee to achieve speeds of up to 4.7km/h[3]

E5, unveiled in 1992, was able to walk autonomously, albeit with a very large head[3]

E6, unveiled in 1993, was able to autonomously balance, walk over obstacles, and even climb stairs[3]
