This week’s Squiz Kids Science Short, we explore how robotic arms really work — from the tiny electrical signals your muscles send, to the clever sensors that help artificial limbs move. And we uncover something surprising: movement is only half the story. To truly work, a robotic limb needs to feel.

So how do scientists restore touch and that hidden superpower called proprioception — your body’s sense of where it is in space?

It’s a fascinating look at biology, engineering and the question at the heart of it all:

If technology works alongside your body… does that make you less human — or simply show how adaptable humans have always been?
