Close call. DR02 and Aliengo trade wins across the matrix.
Readiness, uptime, navigation & connectivity
Price accessibility and ROI clarity
Payload, speed, runtime & labor replacement
Environment fit, footprint & long-term upside
Outdoor security patrols in rain, snow, or dust at industrial sites, power plants, and infrastructure yards
University SLAM and robotics coursework: 4.6 h endurance, developer-friendly I/O (GbE, USB 3.0), and ROS support enable weeks of lab experiments and student projects without infrastructure lock-in.
Both are credible picks. Decide on cost and supplier proximity, not capability — the gap is small.
