EcoFetch is an autonomous drone system that collects waste from cliffs, steep slopes and coastlines where crews currently climb for up to 15 hours per operation. A modular recovery unit mounts under a terrain-adaptive airframe and completes 6 stages in a single flight — detect, fly, land, grip, carry and unload. An onboard AI trained on 50,000+ labeled images identifies and sorts waste into 20+ categories at the point of collection, with detection above 90%. Each flight carries up to 3 kg with 0 human contact, and a servo-driven release empties the carrier box without crew handling. Application targets are over 70% less time and over 40% lower maintenance cost through cross-platform modularity. EcoFetch removes people from the slope entirely, restoring tourist sites and protected terrain that no current collection method can service safely.
