DEEP Robotics
DEEP Robotics X20 is an industrial-grade quadruped robot designed for autonomous inspection and patrol under extreme environmental conditions. The manufacturer — DEEP Robotics (Hangzhou Yunshenshu Technology Co., Ltd.) — positions the X20 as a leading solution for: power & utilities (HV line and substation inspection), rescue operations, tunnels (metro, rail infrastructure), metal & mining, and construction. The robot is commercially deployed with customers worldwide, including Singapore and East Asia.
The X20 is a quadruped with a 12 DOF layout (3 DOF per leg: hip abduction, hip flexion, knee). Standing dimensions: 950 × 470 × 700 mm, mass 53 kg. Frame and housings are made from aerospace aluminium and composites, delivering an industrial-class strength-to-weight ratio. The robot clears obstacles and steps ≥20 cm and slopes ≥30°, making it capable of inspection in open terrain, on stairs and in low-visibility spaces.
Each leg uses electrically actuated joints based on PMSM motors with integrated encoders. Maximum speed ≥4 m/s at gallop. Motion control combines MPC (Model Predictive Control) with reinforcement-learning (RL) policies, ensuring stability on unstructured terrain — grass, gravel, snow, puddles and stairs.
X20 is equipped with multimodal perception sensors: 3D LiDAR (optionally RoboSense RS-LiDAR-32 or Velodyne 32-channel), stereo/RGB-D cameras for obstacle detection and terrain recognition, and an industrial-grade IMU. The compute platform supports: precise GNSS/SLAM navigation, autonomous obstacle avoidance, terrain recognition and human–robot interaction. Mission range up to 15 km on a single charge.
X20 carries up to 20 kg of payload on its back. The modular design enables mounting of multiple peripherals: inspection cameras, manipulators, gas sensors, thermal imagers, millimeter-wave radars, etc. A rich set of interfaces (USB, Ethernet, CAN, RS-485, UART) allows integration of third-party hardware without frame modification.
The robot carries an IP66 ingress protection rating — complete dust protection and resistance to powerful water jets — enabling operation in rain, mud and industrial dust. It operates in extreme temperatures (detailed range not published by the manufacturer, but verified in power utility and mining deployments).
Lithium-ion battery with 2–4 h endurance (depending on payload and terrain) and up to 15 km range. Wired charging. Battery management system (BMS) with online monitoring.
Development platform: Jueying SDK (C++/Python, official DEEP Robotics SDK). ROS 1 (Melodic) and ROS 2 (Humble) support. Autonomous inspection missions handled by the built-in SLAM/navigation stack. The robot supports remote control (gamepad, mobile app), teleoperation and fully autonomous mode. OTA firmware updates.
DEEP Robotics X20 competes directly with Boston Dynamics Spot, ANYbotics ANYmal D and Unitree B2 in the industrial field-inspection segment. It stands out for: the highest payload (20 kg) and range (15 km) in its class, IP66 rating, and a price point below Western equivalents. The company closed a Series C financing round of over 500 million RMB in December 2024, accelerating global expansion.
