Imagine you have a tiny key and a tiny lock. The keyhole is very small and you have to put the key into it without touching the sides. This is like the keyhole problem. It's a puzzle where you have to figure out how to move something through a tight space without touching anything else.
In real life, the keyhole problem can be seen in many situations. For example, surgeons have to perform surgeries through small incisions in the body. They have to move their tools through these openings without touching any of the surrounding tissues. This is like putting the key through the keyhole.
Another example is in space exploration. When we send a rover to explore another planet, we have to make sure it can fit through narrow canyons or crevices without getting stuck. This is like the keyhole problem, we have to figure out how to move something through a small or tight space without touching anything around it.
The keyhole problem is a very important area of study in robotics, manufacturing, and engineering. Engineers and scientists try to come up with innovative ways to overcome the challenge of navigating through small spaces. They use advanced techniques like virtual reality simulations to plan and test their methods.
So, the keyhole problem is like putting a tiny key into a tiny lock without touching anything else around it. It's a puzzle that we try to solve to make surgery, space exploration, and many other things possible.
