Nomad 200

Nomad 200 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 Nomad 200 rather than just read about it. In short: The Nomad 200 or N200 was a commercial research robot manufactured in the 1990s by Nomadic Technologies, Inc. It is an integrated mobile system robot built with different sensing options and was primarily built for laboratory courses in robotics as well as for research and development work.

Key takeaways

Nomad 200 belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Nomad 200 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Nomad 200 from memory before moving on to harder problems.

Reference excerpt

The Nomad 200 or N200 was a commercial research robot manufactured in the 1990s by Nomadic Technologies, Inc. It is an integrated mobile system robot built with different sensing options and was primarily built for laboratory courses in robotics as well as for research and development work.

Description Nomad 200 was a cylindrical robot around 1 metre tall and 20 inches in diameter and moved on three wheels. It could travel at 0.5 metres per second and rotate at 60 degrees per second. It was built as a synchronous system capable of handling three motors: for movement, for turning the wheels, and for turning its turret. The basic robot, comprising the mobile base and the control system, cost $16,000 in 1990. It had a base tactile sensor ring outfitted with 20 independent pressure sensitive sensors. It could be equipped with 16 sonar sensors mounted around the circumference, 16 infra-red sensors. For example, it included a bump sensor that protects the robot from bumps that were not detected by the sonar a magnetic compass. There was also a TV camera and laser rangefinder system and two rows of ten contact sensors. The laser system worked by drawing in space a plane of light, producing a broken line when an object intersects it. The additional sensor systems cost between $1,500 and $7000. It was controlled by an on-board Intel 486 based computer system.

Worked examples

Example 1 — a first encounter with Nomad 200

Start with the simplest possible case. Write down what Nomad 200 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 Nomad 200 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 Nomad 200 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 Nomad 200

In research: Nomad 200 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 Nomad 200 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: Nomad 200 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1994 robots, Cylindrical robots, Robotics stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Nomad 200 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.
