Robot Brain Mission 9 - Invent A Trick Pupil Notes

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

1. Wire only the parts you need.
2. Test the input by itself.
3. Test the output by itself.
4. 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.
