Robot parts, inputs and outputs
Identify inputs, a controller and outputs in a robot system.
Original Kidemy beginner self-study unit · Learn the idea, try the practical activity and review your written answers. Review your project with a guardian or teacher using the criteria below. Teacher-led course approval and booking are separate.
Learn the idea
A robot system receives information, follows programmed rules and produces actions. A sensor provides an input; a controller uses that input; a motor, light or speaker can provide an output. Robotics can begin with paper models and simulations, without buying hardware.
Worked example
A simulated robot detects an obstacle with a sensor. Its controller follows “if blocked, stop”, and its motor output stops moving.
- Name what information enters the system.
- Describe the rule used by the controller.
- Name the action or output that follows.

Show model answer and explanation
output
Movement is an action produced by the system.
Show model answer and explanation
controller
The controller uses input and rules to choose an output.
Write in your own words. A guardian or teacher should review this response.
Show model answer and explanation
Input: low light detected by a sensor. Output: the lamp turns on.
Check that sensing and action are distinguished.
Write in your own words. A guardian or teacher should review this response.
Show model answer and explanation
Use a paper grid or a simulator to test instructions and rules.
Accept a practical model that can represent input, decisions and output.
Robot parts on paper
Draw a robot and label an input, controller and output. Add arrows to show information and action.
Review with a guardian or teacher
- Distinguish sensing from acting.
- Include a clear rule.
- Explain the path from input to output.
