Okay kiddo, have you ever heard of a robot suit? Well, that's sort of what a hybrid assistive limb, or HAL for short, is. It’s a special kind of suit that humans can wear to help them move and do things they might not be able to do on their own.
HAL is made of a lot of parts that are connected together to form a sort of exoskeleton. Think of it like a booster pack that helps you move your arms and legs more easily. The suit actually listens to your brain and helps you move your muscles by sensing the electrical signals that brains send to our muscles.
HALs can be used by many different people, like those who need extra support to walk, people who have had injuries and are undergoing physical therapy, or even people who might work in factories and need to lift heavy things.
The coolest thing about HAL is that it feels like it’s a part of you. When you move, the suit moves — you don’t need to control it separately. HAL helps you do what you want to do, without getting in the way or making things harder.
So, that's what a hybrid assistive limb is, a magical robot suit, that helps you walk or lift things or even dance like a superhero!
