Murata Boy and Murata Girl

Murata Boy and Murata Girl 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 Murata Boy and Murata Girl rather than just read about it. In short: Murata Boy and Murata Girl are two self-balancing robots developed by Murata Manufacturing, a Japanese electronic components company. The company developed the robots to showcase a range of their products and generate publicity.

Key takeaways

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

Reference excerpt

Murata Boy and Murata Girl are two self-balancing robots developed by Murata Manufacturing, a Japanese electronic components company. The company developed the robots to showcase a range of their products and generate publicity. The robots are designed to be as energy-efficient as possible, both in their basic technological components and through features like automatic sleep mode.

Murata Boy Murata Boy is a bicycle-riding robot which, standing 50 cm tall and weighing 5 kg, can travel at a speed up to 2 km per hour. It can balance on the bike moving forwards, backwards, and when remaining still (without planting his feet on the ground). The robot is equipped with:

gyro sensors (for stability and redressing) a shock sensor (for impact detection) an angular velocity sensor a temperature monitor a CCD camera an ultrasonic sensor (for obstacle detection) an infrared sensor (for detecting human movement) an EMI filter (to reduce electronic interference) Wi-Fi and energy-efficient close-distance bluetooth modules (for interaction) Murata Boy was listed on TIME magazine's list of Best Inventions of 2006.

Murata Girl Murata Girl is a unicycle-riding robot released in 2008, standing 50 cm tall and weighing 6 kg that can travel at a speed of 5 cm per second and can ride along a balance beam. She is equipped with the following:

gyro sensors (for stability and redressing) a shock sensor (for impact detection) a temperature monitor a CCD camera an ultrasonic sensor (for obstacle detection) an infrared sensor (for detecting human movement) Wi-Fi and energy-efficient close-distance bluetooth modules

Worked examples

Example 1 — a first encounter with Murata Boy and Murata Girl

Start with the simplest possible case. Write down what Murata Boy and Murata Girl 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 Murata Boy and Murata Girl 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 Murata Boy and Murata Girl 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 Murata Boy and Murata Girl

In research: Murata Boy and Murata Girl 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 Murata Boy and Murata Girl 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: Murata Boy and Murata Girl is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2005 robots, Humanoid robots, Robotics in Japan, so understanding it makes those chapters shorter.
In everyday life: Look for Murata Boy and Murata Girl 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.
