Robotech Defenders

Robotech Defenders 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 Robotech Defenders rather than just read about it. In short: The Robotech Defenders are a line of scale model kits released by Revell during the early 1980s with an accompanying limited comic series published by DC Comics. Contrary to what their name seems to imply, the "'Robotech Defenders'" are not part of the Robotech anime universe adapted by Carl Macek and released by Harmony Gold USA, but they did adopt the same moniker and logo.

Reference excerpt

The Robotech Defenders are a line of scale model kits released by Revell during the early 1980s with an accompanying limited comic series published by DC Comics. Contrary to what their name seems to imply, the "'Robotech Defenders'" are not part of the Robotech anime universe adapted by Carl Macek and released by Harmony Gold USA, but they did adopt the same moniker and logo. The "Robotech Defenders" were one of two "Robotech" lines released by Revell, the other being the "Robotech Changers". The "Robotech Changers" line initially consisted of three models based on the Valkyrie Variable fighter designs from Macross, and the NEBO model, based upon the Orguss of Super Dimension Century Orguss. The "Robotech Defenders" model line was tied into a two-issue limited series of the same name, published by DC comics. It shares many common themes with other science fiction series of that time, including invading aliens, and giant mechanical war machines.

Model review Seeking to capitalize on the Mecha craze of the early 1980s, Model Company Revell went to Japan to look for suitable mecha models prior to 1984. They eventually licensed a number of Takara's Fang of the Sun Dougram models for the "Defenders" line. These models were repackaged with the "Robotech" moniker, and released in North America and Europe. The humanoid Mech models had an average size of 30 cm, the in-scale humans were about 2 cm. One of the features of the models was that they were not static, but had fully movable joints and removable equipment. Because of the complexity, details and parts they can be challenging and require adult skill level even though they were sold with "ages 12 and up" on their packaging. Even experienced modelers found them challenging. In the North American market, the model kits met with much success, appealing to both fans of Robotech and the players of Battletech tabletop strategy game. In Europe, however, model sales were disappointing, possibly due to the non-existent background story included with the models, and the relatively high prices.

Worked examples

Example 1 — a first encounter with Robotech Defenders

Start with the simplest possible case. Write down what Robotech Defenders 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 Robotech Defenders 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 Robotech Defenders 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 Robotech Defenders

In research: Robotech Defenders 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 Robotech Defenders 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: Robotech Defenders is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1985 comics debuts, Comic book limited series, Comics publications, so understanding it makes those chapters shorter.
In everyday life: Look for Robotech Defenders 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.
