36 BIOINSPIRED VERTIPORT SYSTEM DESIGN FOR
SUPPORTING DRONE SWARMS IN METHANE
GAS DETECTION FROM ORPHANED WELLS
FAHAD MANNAN, LOGAN MOORE, JORGE QUIROGA,
ARTHUR WIETHARN, SIHUA SHAO, XIANG SUN, AND
MOSTAFA HASSANALIAN
Bioinspired vertiport designs for drone swarms feature tree-like
structures, solar-powered systems, and protective capsules to
ensure safe, efficient, and sustainable drone operations.
51 GUIDED BY HEARING: ROBOTIC MOTION
PLANNING FOR PRECISION IN GAS LEAKAGE
LOCALIZATION
MOHAMMAD NASR, NIHAR MASURKAR,
POURIA MESHKIZADEH, AND EHSAN DEHGHAN-NIRI
A bioinspired motion planning framework for robots enhances
sound source localization for gas leak detection. By mimicking
animal movements, the method improves estimation using
time-difference-of-arrival (TDOA) data.
