KHR-1

KHR-1 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 KHR-1 rather than just read about it. In short: The KHR-1 is a programmable, bipedal humanoid robot introduced in June 2004 by a Japanese company Kondo Kagaku. At the time of its introduction it was one of the least expensive programmable bipedal robots (prices averaging around $1,600 in the United States and ¥128,000 in Japan).

Key takeaways

KHR-1 belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect KHR-1 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of KHR-1 from memory before moving on to harder problems.

Reference excerpt

The KHR-1 is a programmable, bipedal humanoid robot introduced in June 2004 by a Japanese company Kondo Kagaku. At the time of its introduction it was one of the least expensive programmable bipedal robots (prices averaging around $1,600 in the United States and ¥128,000 in Japan). The robot is 34 cm high and has 17 degrees of freedom (each joint is powered by individual servomotor). It is capable of a wide range of motions, including quick kung-fu-style fighting moves. The KHR-1 can be controlled via RF remote control and modified receiver; however, these units do not come with the robot and must be purchased separately. Other accessories/modifications include additional degrees of freedom (waist and leg motion), a high performance motion processor microcontroller capable of real-time master/slave operation, gyros and multi-axis accelerometers, larger foot/sole plates. The basic robot, as supplied by Kondo, uses simple control application, named HearttoHeart that allows the user to create or capture a sequence of poses and control the transition speeds. The software also has provisions for creating a series of motions into a longer scenario. Users of the KHR-1 have developed a number of more advanced control, programming and simulation applications making it possible to create and modify the robot's movements and scenarios on a personal computer. The KHR-1 is the most commonly used robotic platform used for ROBO-ONE J class robots in Japan. In 2004 the robot won in the Robo-One Jr category (lightweight robots) in the RoboGames (held in the United States). The KHR series also includes the KHR-2HV and KHR-3HV robots.

Worked examples

Example 1 — a first encounter with KHR-1

Start with the simplest possible case. Write down what KHR-1 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 KHR-1 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 KHR-1 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 KHR-1

In research: KHR-1 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 KHR-1 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: KHR-1 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2004 robots, Bipedal humanoid robots, Japanese inventions, so understanding it makes those chapters shorter.
In everyday life: Look for KHR-1 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.

Frequently asked questions

What is KHR-1 in simple terms?

Why does KHR-1 matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study KHR-1?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
