This engineer designed a device to make farm work easier

aspirations: (v. aspire) The longterm  hopes ad goals that drive or motivate someone to not only gain skills and experience but also to achieve challenging things.

3-D: Short for three-dimensional. This term is an adjective for something that has features that can be described in three dimensions — height, width and length.  

agriculture: The growth of plants, animals or fungi for human needs, including food, fuel, chemicals and medicine. 

citrus: A genus of flowering trees that tend to produce fruits with a juicy edible flesh. There are several main categories: oranges, mandarins, pummelos, grapefruits, lemons, citrons and limes. 

consumer: (n.) Term for someone who buys something or uses something. (adj.) A person who uses goods and services that must be paid for. 

crop: (in agriculture) A type of plant grown intentionally grown and nurtured by farmers, such as corn, coffee or tomatoes. Or the term could apply to the part of the plant harvested and sold by farmers.  

engine: A machine designed to convert energy into useful mechanical motion. Sometimes an engine is called a motor. (in computer science) A computer program that performs a particular, narrow range of functions. 

engineering: The field of research that uses math and science to solve practical problems. Someone who works in this field is known as an engineer. 

family: A taxonomic group consisting of at least one genus of organisms. 

fruit: A seed-containing reproductive organ in a plant. 

generation: A group of individuals (in any species) born at about the same time or that are regarded as a single group. Your parents belong to one generation of your family, for example, and your grandparents to another. Similarly, you and everyone within a few years of your age across the planet are referred to as belonging to a particular generation of humans. The term also is sometimes extended to year classes of other animals or to types of inanimate objects (such as electronics or automobiles). 

GPS: Abbreviation for global positioning system, which uses a device to calculate the position of individuals or things (in terms of latitude, longitude and elevation — or altitude) from any place on the ground or in the air. The device does this by comparing how long it takes signals from different satellites to reach it. 

high school: A designation for grades nine through 12 in the U.S. system of compulsory public education. High-school graduates may apply to colleges for further, advanced education. 

laborer: Another name for a worker. 

mechanical: Having to do with the devices that move, including tools, engines and other machines (even, potentially, living machines); or something caused by the physical movement of another thing. 

mechanical engineer: Someone trained in a research field that uses physics to study motion and the properties of materials to design, build and/or test devices. 

navigate: To find one’s way through a landscape using visual cues, sensory information (like scents), magnetic information (like an internal compass) or other techniques. 

physical: (adj.) A term for things that exist in the real world, as opposed to in memories or the imagination. It can also refer to properties of materials that are due to their size and non-chemical interactions (such as when one block slams with force into another). (in biology and medicine) The term can refer to the body, as in a physical exam or physical activity. 

risk: The chance or mathematical likelihood that some bad thing might happen. For instance, exposure to radiation poses a risk of cancer. Or the hazard — or peril — itself. (For instance: Among cancer risks that the people faced were radiation and drinking water tainted with arsenic.) 

robot: A machine that can sense its environment, process information and respond with specific actions. Some robots can act without any human input, while others are guided by a human. 

sensor: A device that picks up information on physical or chemical conditions — such as temperature, barometric pressure, salinity, humidity, pH, light intensity or radiation — and stores or broadcasts that information. Scientists and engineers often rely on sensors to inform them of conditions that may change over time or that exist far from where a researcher can measure them directly. (in biology) The structure that an organism uses to sense attributes of its environment, such as heat, winds, chemicals, moisture, trauma or an attack by predators. 

sibling: An offspring that shares the same parents (with its brother or sister). 

sophisticated: A term for something that is advanced, complex and/or elegant. 

STEM: An acronym (abbreviation made using the first letters of a term) for science, technology, engineering and math. 

system: A network of parts that together work to achieve some function. For instance, the blood, vessels and heart are primary components of the human body’s circulatory system. Similarly, trains, platforms, tracks, roadway signals and overpasses are among the potential components of a nation’s railway system. System can even be applied to the processes or ideas that are part of some method or ordered set of procedures for getting a task done. 

technology: The application of scientific knowledge for practical purposes, or the devices, processes and systems that result from those efforts. 

third party: An agreement generally takes place between two individuals or groups. Each of these is considered a “party” to the agreement. When an additional person or group becomes involved in some way — but did not sign or verbally take part in the initial agreement, it becomes a so-called third party. In some instances, a third party may not even be known to one or more of the individuals who made the initial agreement. 

tool: An object that a person or other animal makes or obtains and then uses to carry out some purpose such as reaching food, defending itself or grooming.
