What are gate errors?

Gate errors are when something goes wrong during a step in a process, making the final result not quite right.

Imagine you're baking cookies. You follow the recipe carefully, mix the flour and sugar, add eggs, and put it all in the oven. But then, the oven door accidentally swings open, letting cold air in. The cookie doesn’t cook properly, it's still soft in the middle. That’s like a gate error. It wasn't your mistake, something went wrong during one of the steps.

Think of a robot that follows instructions to build a tower with blocks. Each instruction is like a gate: "put this block on top," or "move back one step." If a gate error happens, maybe the robot hears "move forward" but moves backward, and the whole tower gets wobbly.

Just like your cookie might be soft in the middle, the robot's tower might not look quite right. Gate errors are small mistakes that can add up and change the final outcome, even if everything else was perfect!
