Magnetic Hall Sensor + laser Emit
Video - Movement
1
A magnet is put near the hall sensor to collect data. If the magnet is close to the sensor, the laser is emitted and the bot moves. Laser was pointing towards the wall to reflect/show effect.
2
Lights off - to show laser

Couldn't find the sensors ( laser emit & magnetic hall sensor) illustration in tinkercad so I used another shape instead
Ultrasonic sensor + buzzer
Video - Movement
When motion is detected and is closer than 20 cm to the ultrasonic sensor, robot moves down then music notes are played and then robot moves up again.

Ultrasonic sensor
Big Sound Sensor + 2 Color LED
Video - Movement
Buzzer sound was played to generate a loud sound to be detected by the sound sensor. If the sound and its intensity does not exceed a limit, the light of the LED is green, and robot does not move. If it exceed the limit, the LED turns red and robot moves
