Code
How does our robot respond?
Mission 1- A pretend fire!
- Draw a fire on the LED.
Mission 2- Red detected?
- Siren → move forward → spray water → LED fire off
Mission 3- Person detected?
- Look around → siren → rescue signal → mission complete
If nothing is detected, the robot waits.
Open the app
Open the Advanced Cubroid app and tap the Group Number icon.
Group NumberMatch the sticker number
Enter the same number shown on the block's sticker.
Power on, then connect
Turn on the blocks and connect them to the app.
Start a new project
Tap the + button to open a new project.
Draw the fire on the LED
Draw two different fire pictures. Showing them one after the other makes the fire blink.
Add the AI detection blocks
Add the red color-detection block and the arms-up pose-detection block.
One function for each detection
Make one action function for each detection block: one for red and one for arms up.
Red found: put out the fire
When red is found, sound the siren. Move forward and act out spraying water. Then turn off the LED fire.
Change the number of forward steps to fit the distance. You can repeat the spraying effect.
Arms up: rescue the person
When raised arms are found, look left and right, sound the siren and send an alert. Then show a smiling face.
Try it out
Check and run the whole program
Tap Play and see what happens.
A friend wears red and raises both arms. What happens?
Is the fire truck moving backward?
If the truck moves backward, tap the motor direction button.
Want it to notice faster?
If detection is slow, set the delay to about 0.5 seconds in Settings, then run it again.
