A cobot is like a robot that helps people with tasks. It's called a "co-bot" because it's supposed to work alongside humans, not replace them.
See, robots can be really good at doing things like lifting heavy things or putting things together really quickly. But sometimes robots have a hard time figuring out what to do next or how to react to unexpected changes.
So a cobot is designed to work with people to do things where robots might struggle. Maybe your mom needs help lifting some heavy boxes, but it's too heavy for you to lift it on your own. A cobot could help you both lift it together!
But cobots are also really useful in factories and workplaces. They can help people assemble things or move things from one place to another. And because they can work alongside people, they can help make work safer and more efficient.
