A LUCKY MATCH: The coming together

Programming level 1

a.) The directly driven, DC motor-driven Comic Mouse rolls to the Comic Cat.

b) Build a Comic Book Mouse mounted on a robot trolley.

The programmed Cartoon Mouse starts automatically on switch-on and moves forward for 5 seconds until it reaches the Comic Cat.

Build the Comic Mouse as in P1 b), 2 Touch sensors, 1 Buzzer attached.
The Comic Mouse starts when one Touch sensor is pressed and stops when the other Touch sensor is pressed, and the Buzzer sounds a high-pitched tone.
Build a Comic Cat mounted on a robot trolley, 1 push button, 1 servo motor, 2 LEDs and 1 Buzzer attached.
The Comic Cat starts when you press the push button and moves forward for a fixed time.
Then it stops and the servo motor mounted in its neck moves its head left and right, while the 2 LEDs in its eyes light up and the Buzzer sounds briefly.
