Project Timeline

Jan 2025 - Jun-2025

OVERVIEW

Developed a functional ceiling-climbing robot designed to navigate inverted surfaces, utilizing a propellor to create negative pressure to adhere to rigid surfaces. Leveraged CAD modeling (SolidWorks) and 3D printing to create optimized prototypes, balancing load capacity and maneuverability. Integrated mechanical, electrical, and control subsystems into a cohesive robotic platform. Conducted iterative testing and troubleshooting to improve adhesion reliability and heat distribution, ultimately enhancing stability and performance. Collaborated within a multidisciplinary team, applying research insights to refine design decisions and deliver an innovative robotics solution.

HighlightS

  • Extended run-time by 50% through iterative propeller redesigns that lowered power consumption while maintaining stable adhesion.
  • Reduced motor temperature by 20% by enhancing airflow with optimized propeller blade profiles, improving thermal management and reliability.
  • Enabled smooth mobility in all four directions by integrating precise control algorithms with mechanical design improvements.
