Honda E series

Honda E series is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Honda E series rather than just read about it. In short: The E series was a collection of successive humanoid robots created by the Honda Motor Company between the years of 1986 and 1993. These robots were only experimental, but later evolved into the Honda P series, with Honda eventually amassing the knowledge and experience necessary to create Honda's advanced humanoid robot: ASIMO.

Key takeaways

Honda E series belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Honda E series to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Honda E series from memory before moving on to harder problems.

Reference excerpt

The E series was a collection of successive humanoid robots created by the Honda Motor Company between the years of 1986 and 1993. These robots were only experimental, but later evolved into the Honda P series, with Honda eventually amassing the knowledge and experience necessary to create Honda's advanced humanoid robot: ASIMO. The fact that Honda had been developing the robots was kept secret from the public until the announcement of the Honda P2 in 1996. E0, developed in 1986, was the 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. The model has 6 degrees of freedom: one in each groin, one in each knee and one in each ankle.

Models E0, developed in 1986. E1, developed in 1987, was larger than the first and walked at 0.25 km/h. This model and subsequent E-series robots have 12 degrees of freedom: 3 in each groin, 1 in each knee and 2 in each ankle. E2, developed in 1989, could travel at 1.2km/h, through the development of "dynamic movement". E3, developed in 1991, travelled at 3km/h, the average speed of a walking human. E4, developed in 1991, lengthened the knee to achieve speeds of up to 4.7km/h. E5, developed in 1992, was able to walk autonomously, albeit with a very large head. E6, developed in 1993, was able to autonomously balance, walk over obstacles, and even climb stairs.

Worked examples

Example 1 — a first encounter with Honda E series

Start with the simplest possible case. Write down what Honda E series claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Honda E series before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Honda E series ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Honda E series

In research: Honda E series appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Honda E series in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Honda E series is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1986 robots, 1987 robots, 1989 robots, so understanding it makes those chapters shorter.
In everyday life: Look for Honda E series outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
