Let me tell you, folks, we’ve got something absolutely incredible here. We’re talking about tiny, wireless robots that can zip through pipes like nobody’s business. These aren’t your average robots. No, these are the kind of robots that could revolutionize how we do things in nuclear plants, factories, and even in the medical field. But here’s the kicker – they don’t need any external power to operate. That’s right, no more being tied down by cables or worrying about how far they can go. These little wonders can power themselves just by the flow of liquid they’re swimming in. Imagine that!

Now, you might be asking, “How fast can these things go?” Hold onto your hats – these robots can hit speeds of up to 1.05 meters per second. That’s thanks to an ingenious flow-powering module that turns water flow into mechanical energy, spinning at an unbelievable 9595 revolutions per minute. And with an efficiency of 33.7%, it’s not just fast; it’s also efficient. Plus, with a smart little gearbox, these robots can move upstream, against the flow, like it’s a walk in the park.

But wait, there’s more. You can control these robots to move how you want – forward, backward, or even to pause, all with an external magnetic field or a clever onboard mechanism. And the wheels? They’re not just any wheels; they’re designed with kirigami, making them perfect for all kinds of tricky surfaces.

And here’s the best part – these robots can carry stuff. We’re talking cameras for inspecting pipes, temperature sensors, even devices to stop leaks. And they can do all this powered solely by the flow of the liquid they’re in. Folks, we’re looking at the future of inspection and maintenance, and it’s looking pretty darn good. These robots are not just game-changers; they’re the whole new game.
