Motorized shopping cart

Motorized shopping cart 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 Motorized shopping cart rather than just read about it. In short: A motorized shopping cart (also known as electric shopping cart) is a shopping cart equipped with an electric motor and navigational controls. It includes a seat (often equipped with an occupant seat switch activating movement of the motorized shopping cart from the occupant's weight) thereby also making it a motorized wheelchair, and it has a rechargeable battery that can be charged by plugging in the device when n…

Key takeaways

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

Reference excerpt

A motorized shopping cart (also known as electric shopping cart) is a shopping cart equipped with an electric motor and navigational controls. It includes a seat (often equipped with an occupant seat switch activating movement of the motorized shopping cart from the occupant's weight) thereby also making it a motorized wheelchair, and it has a rechargeable battery that can be charged by plugging in the device when not in use in order to maximize usage. Motorized shopping carts are provided by supermarkets and other large retail stores for those with permanent or temporary physical disabilities who may have difficulty walking through a large store or pushing a regular cart.

Issues

Theft While shopping cart theft has also been a costly matter for retailers, the higher cost of the motorized carts makes their theft a greater issue to the store, and thereby leads stores to establish policies prohibiting the carts from exiting stores, even though a disabled person may have the need to bring the cart all the way to their vehicle. In May 2009, a Florida man was charged with felony theft of a motorized cart due to its $2,500 value. He was caught not far from the store, riding the cart. Had a non-electric cart been stolen, the theft would have been a misdemeanor. In the same month, two South Carolina men were charged with the theft of a cart, and likewise faced felony charges due to it being valued at over $2,000. Such thefts are rare and difficult to sustain as the carts are obviously grocery store carts, which are designed with a maximum speed of two miles per hour. Most power-operated mobility devices, such as powerchairs and scooters, have an average maximum speed of 5 miles per hour, though many are faster. The baskets and seats are of commercial strength and the wheels are much smaller than those of consumer mobility devices.

Injuries There has been concern over the carts leading to injuries when used by those who do not know how to control them well. The injuries can occur to the user if they crash into an object with the cart, or to a person the user crashes into. To reduce the risk of injury, most carts have a back-up warning system similar to those found on trucks. They also are programmed with a low maximum speed of up to two miles per hour. In Louisiana in 2011, a lawsuit was filed by a woman who claimed injury while using a motorized shopping cart. The case was dismissed as the defendant filed a motion asserting that the accident and injuries were caused by the woman's own actions and she could not meet the burden of proof. The store manager immediately tested the cart after the claimed injury and further testing was done by the store mechanic and an engineer.

Permission to use

While motorized shopping carts are generally reserved for disabled people, most stores will take one's word for being disabled and will not challenge one's need for a cart. However, there have been cases reported in which a person with a non-visible disability has requested the use of a motorized cart, but has been denied the use by store employees who did not believe the customer had a disability. There has also been concern over minors using the carts. In January 2009, a Wal-Mart store in Tennessee did not allow an 11-year-old girl with a broken leg to use a motorized cart, despite the fact that she had been allowed by other stores to use them.

Worked examples

Example 1 — a first encounter with Motorized shopping cart

Start with the simplest possible case. Write down what Motorized shopping cart 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 Motorized shopping cart 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 Motorized shopping cart 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 Motorized shopping cart

In research
Motorized shopping cart 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 Motorized shopping cart 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
Motorized shopping cart is common in secondary-school and first-year university syllabi. It links to neighbouring topics Electric vehicles, Mobility devices, Shopping carts, so understanding it makes those chapters shorter.
In everyday life
Look for Motorized shopping cart 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.
