Marvin (robot)

Marvin (robot) 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 Marvin (robot) rather than just read about it. In short: Mobile Autonomous Robot Vehicle for Indoor Navigation (Marvin) is a mobile robot developed at Robotics Lab at University of Kaiserslautern, Germany. This platform consists of a differential drive, a bumper for basic operational safety, planar laser range scanners at the front and back side for obstacle detection, a belt of ultrasonic sensors for recognizing jutting edges such as table tops, a web cam, another fixed…

Key takeaways

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

Reference excerpt

Mobile Autonomous Robot Vehicle for Indoor Navigation (Marvin) is a mobile robot developed at Robotics Lab at University of Kaiserslautern, Germany. This platform consists of a differential drive, a bumper for basic operational safety, planar laser range scanners at the front and back side for obstacle detection, a belt of ultrasonic sensors for recognizing jutting edges such as table tops, a web cam, another fixed laser scanner at a height of one meter for a view free of clutter and a stereo microphone system for localization of sound sources. Its control system follows a behavior-based approach and its mapping abilities rely on a 2D geometric and topological strategy.

Technical specifications Length: 72 cm Width: 72 cm Height: 120 cm Weight: about 80 kg Payload: about 100 kg Power Supply: 2 lead batteries, each 12V Operation Time: 3 hours Drive: Differential drive with 2 electric motors Max. Speed: 4.3 km/h Controller: 2 Maxon-Motor control system, controlled through a DSP-Board Computer: 1 onboard PC Sensors: 2 Sick AG Laser scanners, Ultrasonic belt, 2 Microphones, Camera on pan-tilt unit

Worked examples

Example 1 — a first encounter with Marvin (robot)

Start with the simplest possible case. Write down what Marvin (robot) 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 Marvin (robot) 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 Marvin (robot) 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 Marvin (robot)

In research: Marvin (robot) 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 Marvin (robot) 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: Marvin (robot) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2000s robots, Differential wheeled robots, Individual robots, so understanding it makes those chapters shorter.
In everyday life: Look for Marvin (robot) 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.
