A robot is a programmable machine that can sense its environment, process data, and automatically perform physical actions with partial or full autonomy.
Core Components of a Robot
Every robot relies on three fundamental systems to operate:
- Sensors: Devices like cameras, lidar, or microphones that gather information about the surrounding world.
- Controller (Brain): A computer program or processor that analyzes sensor data and decides what action to take.
- Actuators (Muscles): Motors, pistons, or gears that turn electrical commands into physical movement or object manipulation.
How Robots Work: The Sense-Think-Act Loop
- Sense: The robot collects data from its environment through its sensors.
- Think: The internal processor or AI evaluates the information based on pre-written instructions or learned patterns.
- Act: The controller sends a signal to the actuators to move, pick up an object, or change direction.
