How Mova does on its tests: [the lesson at school](https://md.mova.elamur.ai/free/en/school-run/technology/39-robots-at-work-and-at-home/). - [1](https://md.mova.elamur.ai/free/en/corpora/school/technology/39-robots-at-work-and-at-home/1/) — A robot vacuum feels a chair leg with its bumper, its program says turn, and its wheels turn; that sense, decide, move loop is the heart of every robot, from a toy to a Mars rover. - [2](https://md.mova.elamur.ai/free/en/corpora/school/technology/39-robots-at-work-and-at-home/2/) — In a car factory, big robot arms weld and paint the same way thousands of times without getting tired or bored, so they work behind fences where people cannot wander in. - [3](https://md.mova.elamur.ai/free/en/corpora/school/technology/39-robots-at-work-and-at-home/3/) — Smaller cobots are built to work beside people and stop the moment they touch someone. - [4](https://md.mova.elamur.ai/free/en/corpora/school/technology/39-robots-at-work-and-at-home/4/) — Robots also go where people should not: a bomb-disposal robot rolls up to a suspicious bag while the police stay far away, and a rover drives on Mars, where no person has ever stood. - [5](https://md.mova.elamur.ai/free/en/corpora/school/technology/39-robots-at-work-and-at-home/5/) — Even a smart robot is not a person and can make mistakes. - [6](https://md.mova.elamur.ai/free/en/corpora/school/technology/39-robots-at-work-and-at-home/6/) — A surgical robot moves only when the surgeon moves its controls, and a robot lawnmower does not see a hedgehog in the dark, so people stay in charge and stay careful. - [7](https://md.mova.elamur.ai/free/en/corpora/school/technology/39-robots-at-work-and-at-home/7/) — A factory robot is controlled by a computer that drives motors in each joint, and sensors and cameras help it pick, place, weld or paint the same way every time; big ones work behind fences or slow down and stop near people. - [8](https://md.mova.elamur.ai/free/en/corpora/school/technology/39-robots-at-work-and-at-home/8/) — A cobot, or collaborative robot, is a smaller robot made to work beside people; it senses touch and stops if it bumps someone, and it can be taught by moving its arm by hand. - [9](https://md.mova.elamur.ai/free/en/corpora/school/technology/39-robots-at-work-and-at-home/9/) — A robot vacuum uses sensors, and sometimes a spinning laser or a camera, to map the room, bumps gently into things and returns to its dock to charge; pick up small toys, cables and socks before it runs. - [10](https://md.mova.elamur.ai/free/en/corpora/school/technology/39-robots-at-work-and-at-home/10/) — A robot lawnmower stays inside a hidden wire or uses GPS and cuts a little grass every day; keep children and pets away, never pick it up while it is running, and run it in the day, because it can hurt hedgehogs at night. - [11](https://md.mova.elamur.ai/free/en/corpora/school/technology/39-robots-at-work-and-at-home/11/) — A delivery drone carries a small parcel, flies a planned route with GPS and lowers the parcel down; some countries use drones to deliver medicines to remote places. - [12](https://md.mova.elamur.ai/free/en/corpora/school/technology/39-robots-at-work-and-at-home/12/) — Pavement delivery robots are small robots on wheels that use cameras and sensors to drive along pavements; in Milton Keynes six-wheeled ones deliver groceries, and people should give them space and never climb on them. - [13](https://md.mova.elamur.ai/free/en/corpora/school/technology/39-robots-at-work-and-at-home/13/) — Warehouse robots carry whole shelves or boxes to human pickers, following codes on the floor, and in some warehouses robots zip around on a grid picking boxes from above. - [14](https://md.mova.elamur.ai/free/en/corpora/school/technology/39-robots-at-work-and-at-home/14/) — In robotic surgery the surgeon sits at a console and controls the robot arms, which make very small, steady movements; the surgeon is always in charge and the robot does not decide. - [15](https://md.mova.elamur.ai/free/en/corpora/school/technology/39-robots-at-work-and-at-home/15/) — A bomb-disposal robot is a tracked robot with cameras and an arm, driven by remote control, so people can stay far away from danger. - [16](https://md.mova.elamur.ai/free/en/corpora/school/technology/39-robots-at-work-and-at-home/16/) — Never touch a suspicious object or bag; move away and tell an adult. - [17](https://md.mova.elamur.ai/free/en/corpora/school/technology/39-robots-at-work-and-at-home/17/) — A Mars rover drives itself short distances, takes photos and tests rocks, because radio signals take minutes to travel between Mars and Earth, too slow to steer it with a joystick. - [18](https://md.mova.elamur.ai/free/en/corpora/school/technology/39-robots-at-work-and-at-home/18/) — The rover Perseverance carried a small helicopter called Ingenuity, which flew on Mars, the first powered flight on another planet. - [19](https://md.mova.elamur.ai/free/en/corpora/school/technology/39-robots-at-work-and-at-home/19/) — Robots take over repetitive tasks, but people still design, build, fix and run them. - ← previous: [Satellites and GPS](https://md.mova.elamur.ai/free/en/corpora/school/technology/38-satellites-and-gps/) - next →: [Self-driving cars and machines that run themselves](https://md.mova.elamur.ai/free/en/corpora/school/technology/40-self-driving-cars-and-machines-that-run-themselves/) - ↑ back to [Technology](https://md.mova.elamur.ai/free/en/corpora/school/technology/)
