Remote-control vehicle

Remote-control vehicle is a science 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 Remote-control vehicle rather than just read about it. In short: A remote-control vehicle is defined as any vehicle that is teleoperated by a means that does not restrict its motion with an origin external to the device. This is often a radio-control device, a cable between the controller and the vehicle, or an infrared controller.

Key takeaways

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

Reference excerpt

A remote-control vehicle is defined as any vehicle that is teleoperated by a means that does not restrict its motion with an origin external to the device. This is often a radio-control device, a cable between the controller and the vehicle, or an infrared controller.

Applications

Scientific Remote-control vehicles have various scientific uses, including operating in hazardous environments, working in the deep ocean, and space exploration.

Space probes The majority of probes to other planets in the Solar System have been remote-control vehicles, although some of the more recent ones were partially autonomous. The sophistication of these devices has prompted greater debate on the need for crewed spaceflight and exploration. The Voyager I spacecraft is the first craft of any kind to leave the Solar System. The explorers Spirit and Opportunity have provided continuous data about the surface of Mars since January 3, 2004.

Submarines Jason is the Woods Hole Oceanographic Institution's deep water explorer and can withstand depths of up to 6,500 feet. The Scorpio ROV is a British submersible that rescued the crew of the Russian AS-28 on August 7, 2005.

Military and law enforcement

Military usage of remotely-controlled vehicles dates back to the first half of 20th century. John Hays Hammond, Jr., invented and patented methods for wireless control of ships starting in 1910. The Soviet Red Army used remotely-controlled teletanks during the 1930s in the Winter War and early stage of World War II. There were also remotely-controlled cutters and experimental remotely-controlled planes in the Red Army. Remote-control vehicles are used in law enforcement and military engagements for some of the same reasons. Hazard exposure is mitigated for the operator of the vehicle, who controls it from a location of relative safety. Remote-controlled vehicles are also used for bomb disposal. Unmanned aerial vehicles (UAVs) have undergone a significant evolution in capability in the past decade. Early UAVs were capable of reconnaissance missions alone and then only with a limited range. Current UAVs can hover around possible targets until they are positively identified before releasing their payload of weaponry. Backpack-sized UAVs will provide ground troops with over-the-horizon surveillance capabilities.

Recreation and hobby

Small-scale remote-control vehicles have long been popular among hobbyists. These remote-controlled vehicles span a wide range in terms of price and sophistication. There are many types of radio-controlled vehicles; these include on-road cars, off-road trucks, boats, submarines, airplanes, and helicopters. The "robots" now popular in television shows such as Robot Wars are a recent extension of this hobby. Radio control is the most popular choice, as the vehicle's range is not limited by the length of a cable, nor does it require direct line-of-sight with the controller, which is the case with infrared control.

Worked examples

Example 1 — a first encounter with Remote-control vehicle

Start with the simplest possible case. Write down what Remote-control vehicle claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Remote-control vehicle 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 Remote-control vehicle 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 Remote-control vehicle

In research: Remote-control vehicle appears in science 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 Remote-control vehicle 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: Remote-control vehicle is common in secondary-school and first-year university syllabi. It links to neighbouring topics Uncrewed vehicles, so understanding it makes those chapters shorter.
In everyday life: Look for Remote-control vehicle 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.
