- New model boosts speed, payload, durability and most notably, water tolerance
- Designed for power inspection, firefighting and security scenarios
DEEP Robotics (云深处科技), a Chinese leader in quadrupedal robotics and embodied AI, has released a new version of its industrial quadruped robot, the Lynx M20S, expanding capabilities in speed, payload and environmental resilience as it targets broader deployment across infrastructure and emergency scenarios.
Launched on April 27, the M20S builds on its predecessor with upgraded protection, mobility and endurance.
The robot is rated at IP67, allowing it to withstand submersion in up to one meter of water for 30 minutes, and operate in conditions such as heavy rain or flooding.
Its operating temperature range has been extended to between -30°C and 55°C, enabling use in extreme climates including northern China’s cold regions like Hulunbuir and Mohe.
The system is designed to support applications such as firefighting and emergency response, where it can traverse flooded or hazardous terrain, as well as low-noise environments like security patrols.
Operating noise has been reduced to 55 decibels or lower, allowing it to function in quiet settings without disruption.
The M20S has a top speed of 9 meters per second, placing it at the higher end of its category, while battery life ranges from 3.5 to 5 hours without load and 2.5 to 3.5 hours under load. A dual-battery hot-swapping system enables continuous operation without shutdown.
The robot is positioned for use in power infrastructure inspection, where it can cover multiple checkpoints quickly, navigate complex terrain such as slopes and stairways, and sustain long-duration operations in outdoor environments.
Equipped with proprietary AI motion control algorithms, the M20S can adapt its posture and gait in real time to handle uneven terrain including mud, rubble and steep steps.
It also features dual wide-angle LiDAR sensors for navigation, enabling autonomous positioning, obstacle avoidance and route planning.
Despite maintaining the same overall weight as the previous model Lynx M20, the robot’s payload capacity has increased significantly, reaching up to 35 kilograms on flat terrain—more than double that of its predecessor.
It can also climb steps of 20 to 25 centimeters and traverse obstacles up to 60 to 80 centimeters in height.
The platform supports modular attachments for inspection, surveillance and transport tasks, extending its potential use cases to areas such as logistics, equipment deployment and emergency material delivery.
