Adaptive Automotive Headrest for Shared Vehicles

Heavy snowfall is unpredictable and can cause pedestrian slip accidents if not removed promptly. Existing snow-removal systems are designed for vehicles and large spaces, making them unsuitable for narrow pedestrian areas such as sidewalks and stairs. This project develops a compact autonomous snow-removal mobility system for pedestrian environments.

Questions

Q1. How can snow be removed in complex pedestrian environments?

  • Limited access for vehicles
  • Risk of ice formation
  • Size vs. performance trade-off

Q2. Can snow removal be performed without human intervention?

  • Safety risks in manual work
  • Need for continuous operation

Q3. How can safety be ensured around pedestrians?

  • Visibility
  • Speed control
  • Emergency response
