Tiny Robots, Big Potential: What's Holding Them Back?

Tiny robots, smaller than the width of a human hair, are no longer just a dream. They are real and have the power to change the world. But why aren't we seeing them everywhere yet? The journey of these micro and nanorobots started with a famous lecture and a sci-fi movie. Now, they are used in medicine and cleaning up the environment. But there are big hurdles to overcome. First, these tiny robots need a way to move around. Scientists are working on different methods to propel them. But it's not just about movement. The robots need to be smart, work together, and be made from the right materials. Plus, they need to be produced in large numbers and follow safety rules. Making these robots a reality isn't just a technical challenge. It's also about ethics, business, and the environment. Scientists need to work together across different fields to tackle these issues. The goal is to make these tiny robots a common tool for solving big problems and improving lives.
