Quadruped Robots

Most popular affordable robot dog.

Xiaomi's consumer robot dog. NX chip, affordable.

Most advanced commercial quadruped. Inspection & data collection.

Spot with the 6-DOF robotic arm — the most deployed quadruped manipulator in the world. Spot Arm lifts up to 11kg, opens doors, operates valves, collects samples, and performs contact inspection tasks in hazardous environments. Used at Chevron, Aker BP, and nuclear decommissioning sites. Integrates with MoveIt 2 for manipulation planning.

Xiaomi's second-generation consumer quadruped — most affordable AI robot dog with a robotic arm. CyberDog Pro adds a 6-DOF gripper arm to the CyberDog 2 chassis, enabling pick-and-place and manipulation tasks. Features NVIDIA Jetson Orin onboard AI and open-source ROS2 SDK. Popular with university robotics clubs and hobbyists worldwide.

Military-grade quadruped robot selected by US Air Force and Army for base security. Ghost Robotics Vision 60 is the backbone of the US DoD's ROGUE (Robotic Unmanned Ground Vehicles) program — 40+ units deployed at Tyndall Air Force Base. IP67 waterproof, operates in -30°C to +55°C, mounts payloads up to 20kg including SWORD defense systems.

The most affordable high-performance quadruped outside China — Phantom Aria's carbon fiber frame weighs only 8kg yet achieves 6m/s sprint speed and 90-minute runtime. Full ROS2 API with Python SDK enables research-grade customization. Targets university labs and startup robotics teams priced out of Spot ($75K) or ANYmal ($200K+). 800 pre-orders in 72 hours of launch. Ships Q3 2026 from Sheffield, UK. Fully open-source hardware design files.

Next-generation Spot with onboard AI and extended runtime. Spot S2 doubles the battery life to 120 minutes, adds an onboard NVIDIA Jetson Orin for edge AI inference, and integrates Scout's cloud fleet management natively. New Spot Arm 2 handles 10kg payload with improved manipulation. Autonomous docking charges while on duty.

World's first wheel-legged hybrid quadruped. Unitree B2-W adds omnidirectional wheels to the B2 platform — each foot has a motorized wheel, enabling 6m/s flat-ground speed while retaining full stair-climbing and rough terrain capability. 4kWh battery gives 3-hour runtime. Used in logistics and factory patrol.

Industrial quadruped. 40kg payload, IP67.

China's leading industrial inspection quadruped. Deep Robotics X30 Pro is deployed at CNOOC oil platforms, State Grid substations, and CRRC railway depots. IP67 rated, -20°C to +55°C, 2-hour inspection runs. The onboard AI detects equipment anomalies with 94% accuracy and transmits real-time reports to plant operators.

Affordable research quadruped with ROS2 support. Weilan AlphaDog V3 is widely used in Chinese universities for legged locomotion research — 300+ academic lab deployments. Open SDK, ROS2 native, 8DOF per leg (32 total). At $8,500, it undercuts Unitree Go2 Pro while offering higher joint torque for research applications.

ATEX-certified autonomous inspection robot for oil & gas.

6-legged hexapod research platform from Carnegie Mellon spin-out. HEBI Daisy provides extreme terrain adaptability — each of its 6 legs has 3 DOF X-series modules, enabling walking on rubble, stairs, and uneven ground. Popular in search-and-rescue research and disaster response labs.
