Mission 9: Invent A Trick
Big Question
Can you combine an input and an output to make the robot do something surprising?
Your Mission
Invent a small robot trick. A trick has a trigger, a reaction, and a way to show that it worked.
Parts
Choose:
- one input, such as distance, tilt, button, or message
- one output, such as LED, matrix, or sound if available
Plan
Fill in this sentence:
When the robot senses **_____**, it will **_____**.
Example:
When the robot sees my hand close by, it will show a surprised face.
Build
- Wire only the parts you need.
- Test the input by itself.
- Test the output by itself.
- Combine them after both parts work.
Try It
Run your trick three times.
Each time, ask:
- Did it trigger at the right moment?
- Was the reaction clear?
- Did anything happen by accident?
Success Check
- Your input changes a value or state.
- Your output reacts.
- Another person can understand the trick without you explaining every wire.
Debug
If the trick is unreliable:
- Make the trigger simpler.
- Use a bigger threshold gap.
- Slow the reaction down.
- Test one part at a time again.
Remix
Add a second reaction.
For example, show a face and blink the LED.
Robot Brain Idea
Robots feel more alive when inputs and outputs are connected. The brain senses something, decides what it means, and responds.
