Parts of a robotic system
A robotic system is a machine that can sense, decide and act on its own. It has three main jobs, which we call input, process and output.
- Input: a sensor collects information, such as light, sound, touch or distance.
- Process: the controller (a small computer) reads the input and follows the program.
- Output: a motor, light or buzzer does the action.
Key idea
A robotic system follows the flow: input (sensor) → process (controller) → output (motor).
Writing simple code
A program is a list of clear steps the controller follows in order. We often use an if rule: if a condition is true, then do an action.
Example
If the distance sensor sees a wall, then stop the motor and turn. This stops a robot car from crashing.
Testing and fixing
After you run the code, you watch what the robot does. If it does the wrong thing, you find the mistake, called a bug, and change the code. Testing and fixing the code again and again makes the robot work well.
