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.
