HOAP

HOAP 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 HOAP rather than just read about it. In short: The HOAP series robots are an advanced humanoid robot platform manufactured by Fujitsu Automation in Japan. HOAP is an abbreviation for "Humanoid for Open Architecture Platform".

Key takeaways

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

Reference excerpt

The HOAP series robots are an advanced humanoid robot platform manufactured by Fujitsu Automation in Japan. HOAP is an abbreviation for "Humanoid for Open Architecture Platform". The HOAP series should not be confused with the HRP series (also known as Promet).

History In 2001, Fujitsu realized its first commercial humanoid robot named HOAP-1. The HOAP-2 was released in 2003 followed by the HOAP-3 in 2005.

Specifications of HOAP-2 HOAP-2 is 1 ft 7 in (48 cm) high and weighs 15 lb (6.8 kg). Its system consists of the robot body, PC and power supplies, and the PC OS uses RT-Linux (open C/C++language). The robot's smooth movement was achieved because the electric current control of the motor was possible (except neck and hand). The USB interface for the internal LAN facilitates easy modification or addition of new actuators and sensors. The neck, waist and hands now have movement capability, allowing smooth movement. The robot is easy to program and has a simple initial start up using a sample program included with the purchase of the robot.

Capabilities of HOAP-2 HOAP-2 has been demonstrated with capabilities to successfully perform various tasks, including walking on flat terrain, performing sumo movements, cleaning a whiteboard, following a ball, and grasping thin objects, such as pens and brushes.

Worked examples

Example 1 — a first encounter with HOAP

Start with the simplest possible case. Write down what HOAP 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 HOAP 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 HOAP 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 HOAP

In research: HOAP 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 HOAP 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: HOAP is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2001 robots, Bipedal humanoid robots, Robotics at Fujitsu, so understanding it makes those chapters shorter.
In everyday life: Look for HOAP 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 HOAP in simple terms?

The HOAP series robots are an advanced humanoid robot platform manufactured by Fujitsu Automation in Japan. HOAP is an abbreviation for "Humanoid for Open Architecture Platform".

Why does HOAP 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 HOAP?

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.
