This invention introduces three robotic systems through a quadruped robot dog equipped with multi-sensor feet for environmental and structural sensing in challenging or hazardous locations.
The invention centers around a Quadruped Robot Dog (QRD) that integrates sensors on its feet to measure moisture, temperature, humidity, and seismic moduli using piezoelectric patches. The robot can drop a small object and measure wave propagation to determine material stiffness, making it useful for structural integrity assessments. Its mobility allows access to uneven or dangerous terrain, unlike traditional stationary instruments, which require manual repositioning. Two additional concepts expand its functionality: one system that wirelessly transmits sensor data for global access, and an ESP32-CAM-based bristle-bot with AR finger control for navigating confined spaces. Collectively, these designs improve safety, efficiency, and accessibility for environmental and structural monitoring.
