Product Features
20 kg Agile Chassis — Navigate Tight Spaces with Ease
Weighing just 20 kg with a standing footprint of 650 × 370 × 485 mm and a crouched height of only 230 mm, the D20 is the lightest full-featured model in the LingMou series. It seamlessly transitions from narrow stairwells and low-profile utility corridors to open campuses — truly all-scenario ready. From community patrol to chemical plant inspection, one unit covers every route.
Quad-Sensor Fusion, All-Weather Environmental Awareness
Integrates 3D LiDAR + depth camera + ultrasonic + low-light camera into a four-sensor suite. Whether under harsh daylight, near-darkness, or smoke-obscured conditions, the D20 maintains stable situational awareness. A wide-angle camera mounted on the head, paired with the onboard navigation host, delivers real-time all-terrain 3D mapping and autonomous navigation.
Sub-Second AI Smart Alerts — Proactive Security
A built-in real-time AI analytics engine at the front end detects anomalies — intrusions, crowd gathering, physical altercations, fire & smoke — within seconds and reports instantly. The rear intelligent controller supports automatic smoke and open-flame detection with alerts, upgrading from "reactive response" to "proactive early warning" at sub-second response speed.
7×24 Nonstop Patrol — Eliminate Human Blind Spots
Purpose-built for routine watch duty, supporting autonomous docking/charging and scheduled patrol task orchestration for round-the-clock, all-terrain continuous coverage. It completely eliminates the temporal blind spots and coverage gaps of manual inspection — a single D20 can handle multiple shift equivalents of repetitive patrol duty.
3 m/s High-Speed Mobility + IP65 All-Terrain Protection
Top speed of 3 m/s, maximum climb angle ≥30°, obstacle clearance ≥16 cm — effortlessly handles stairs, ramps, and gravel surfaces. IP65 ingress protection, operating temperature range -20 ℃ ~ 50 ℃, ensuring reliable performance in rain, dust, extreme heat, or freezing cold — meeting the harshest outdoor perimeter and industrial plant requirements.
Modular Architecture + Open Ecosystem, Customizable on Demand
Supports OTA remote upgrades for continuous capability evolution. Open hardware interfaces and data integration APIs enable secondary development and modular payload expansion. Customizable 7/10-inch HD remote-control handles (supporting Wi-Fi, Bluetooth, 4G/5G, HDMI) provide real-time robot-eye view, battery level, signal strength, and other operational telemetry — meeting the customized deployment needs of every industry.
