Chuskit Goes to School (Smart Servo Ramp & Wheelchair Assist)
Source: Stemoto Original
Chuskit uses a wheelchair and cannot climb school stairs. Construct a motorized accessibility ramp with a servo motor arm that deploys over stairs when a wheelchair presence sensor is activated.
Categorisation
Props & Materials Required
- •Staircase & accessibility ramp model kit
- •Mini toy wheelchair with Chuskit figure
- •HC-SR04 ultrasonic wheelchair detection sensor
- •SG90 micro servo motor (deploys ramp over stairs)
- •ESP32 / micro:bit V2 controller
- •DFPlayer Mini MP3 module + 3W speaker
Step-by-Step Instructions
Wheelchair Approaches Stairs
Drive toy wheelchair toward school entrance stairs.
Ultrasonic Presence Detection
Ultrasonic sensor detects wheelchair waiting at bottom of stairs.
Servo Ramp Deployment
Servo motor activates! Smooth accessibility ramp lowers over the steps automatically.
Chuskit Enters School
Wheelchair rolls smoothly up the ramp into school! Speaker celebrates: 'Chuskit is at school! Accessible design for everyone!'
Why It Works & Notes
Chuskit Goes to School teaches disability inclusion and accessibility. Building a smart motorized ramp that deploys automatically over stairs when a wheelchair approaches teaches inclusive engineering.
