# How Robots Actually Work: Sense, Plan, Act

When people hear "robot" they picture a humanoid, but the vast majority of working robots are stationary arms and mobile platforms. Amazon alone runs more than 750,000 of them.

At the core, every robot runs the same loop: sense the environment through cameras, LiDAR, force sensors, and encoders, plan a response, then act. That cycle repeats thousands of times a second.

The interesting shift is where robotics meets AI. Traditional robots follow fixed programs. Add a learning layer and the machine can handle noisy data, adapt to new situations, and perform tasks it was never explicitly coded for.

For the [full picture, from core components to robot types to the robotics and AI overlap, this guide breaks it down in plain language](https://www.learnhowtoscience.com/robotics-explained/).
