When you usually think of robots you think of a movie where a mad scientist makes a robot and then it gets smarter and takes over or a robot comes from space and tries to destroy humanity. And this is one of the reasons I think robotics isn't advancing like it should because people think that they will take over the world.
Robots do alot of good for us they can build thing faster and better than us. They can also go places we cant go like the bottom of the sea or to a far planet in space. Like the Mars rover it roves around Mars but we cant send humans there because theres no way to bring enough food and water so we send a robot because they don't need food or water. And with robots we can learn way more stuff but without them we would hardly know anything.
When you think of robots you usually think of something computerized and mechanical but there are other types like soft bodied air pumped robots. That are made out of some kind of gel and how it works is it has tubes connected to it that pump air to different sections to let it move. Click here and here
