Quadruped Robots 四足机器人

Quadrupeds trade the simplicity of wheels for the reach of legs: they climb stairs, cross rubble and right themselves, making them ideal for inspection, security and research. Boston Dynamics’ Spot proved the concept; Unitree and others then drove prices down by orders of magnitude, turning quadrupeds into an accessible developer platform.

Beyond their own use cases, quadrupeds have become the proving ground for the legged-locomotion and reinforcement-learning techniques now feeding directly into humanoids — a cheaper, safer body on which to learn how to walk.

What to watch

• Price collapse opening quadrupeds to developers
• Industrial inspection as the leading commercial use
• Locomotion learning transferring to humanoids
