George (robot)

George (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 George (robot) rather than just read about it. In short: George is a British humanoid robot created by Tony Sale in 1949. The robot was built using scrap metals from a crashed RAF Wellington bomber.

Key takeaways

George (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 George (robot) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of George (robot) from memory before moving on to harder problems.

Reference excerpt

George is a British humanoid robot created by Tony Sale in 1949. The robot was built using scrap metals from a crashed RAF Wellington bomber. George was reactivated in 2010 by Sale and is on display at The National Museum of Computing at Bletchley Park.

History In 1949 Tony Sale used the scrap metal from a grounded Wellington bomber to build a simple 6-foot (1.8 m) humanoid robot he named George. The construction cost for the robot was about £15. Actually, this robot could be considered George Mark IV, as Sale had already built a very basic robot in his parents' garage when he was 12 and named it George, plus two later versions. The last George robot, the only one extant, was built when Sale joined the Royal Air Force in 1949 as a radar instructor at the RAF Debden base in Essex. It could walk, turn the head, move its arms and sit down. It was powered by a pair of motorcycle batteries put inside his chest. The robot could also move his jaw to speak and be controlled by radio remote. The external cover of the body was made in aluminium and duralumin. George was put on display at the open days at the RAF Debden base and also appeared on television.

2010 reactivation In November 2010 Tony Sale reactivated George after 45 years of total inactivity. The robot had been stored in Sale's garage. The original batteries were replaced with new lithium batteries and some minor fixing occurred. Sale described the process with the words: "I dug him out of the garage where he had been standing for 45 years, I had a fair bit of confidence he would work again and luckily I was right. I put some oil on the bearings and added a couple of new lithium batteries in his legs, switched him on and away he went. It was a lovely moment." The event gathered worldwide news-media attention, and George's reactivation was shown in the third episode of Wallace and Gromit's World of Invention. After the reactivation, Tony Sale donated George to the National Museum of Computing, where it remains on display to the public.

2020 exhibition On 15 March 2020, the robot was put up for display as part of the Robots Exhibition on Tekniska museet in Stockholm, Sweden.

Worked examples

Example 1 — a first encounter with George (robot)

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

In research: George (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 George (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: George (robot) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1949 robots, Humanoid robots, Robots of the United Kingdom, so understanding it makes those chapters shorter.
In everyday life: Look for George (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.
