Once upon a time, there was a little robot named Rusty. Rusty was made up of many joints that allowed him to move and perform different tasks. One of the joints in Rusty's arm was called a hinge joint. This joint allowed Rusty's arm to bend and straighten, just like the hinge on a door.

Another joint in Rusty's body was called a ball-and-socket joint. This joint allowed Rusty's arm to move in all directions, just like a swivel. It was this joint that allowed Rusty to twist and turn his arm to reach for things.

Rusty also had joints in his legs that allowed him to walk and run. These joints allowed for a lot of movement and flexibility, just like the joints in our own bodies.

One day, while Rusty was playing, he noticed that one of his sutures had come undone. A suture is a type of joint that holds parts of Rusty's body together. Without this suture, Rusty's arm was no longer secure and it kept falling off.

Rusty was very sad and didn't know what to do. But then, he remembered that he was made up of many different joints and that he could still move and perform tasks, even with one arm.

So, Rusty decided to be brave and went to see the robot doctor. The doctor fixed Rusty's suture, and soon he was good as new.

From that day on, Rusty never forgot the importance of his joints and how they allowed him to move and play. He took good care of himself and was always ready for his next adventure.

The end.
