自由度
机器人工程中指机械系统独立运动的数量，完全自由的刚体在三维空间中有6个自由度（3个平移+3个旋转），是衡量机器人运动灵活性的核心指标

Degrees of freedom is a commonly used metric in traditional robotics for describing hand dexterity, but it cannot fully reflect actual operational capability.
12 degrees of freedom typically correspond to a six-legged layout with 2 servos per leg, or a four-legged layout with 3 servos per leg.
将运动规划与执行跟踪耦合在一起（每帧同时重算动作与平衡）会导致计算量随自由度数量指数级膨胀，人形机器人通常有二三十个以上自由度，极易超出实时计算预算。
The higher the degrees of freedom, the greater the computational complexity of motion control, which increases exponentially.
Degrees of freedom (DOF) refers to the number of independent directions or axes along which a robotic arm can move; industrial-grade robotic arms typically have 6 DOF.
工业机器人通常需要6个自由度才能在三维空间中实现任意位置和姿态的定位，其中3个用于位置、3个用于姿态
第一视角数据存在动作与机器人本体之间的具身鸿沟（embodiment gap），因为人手有五根手指、27个自由度，而机器人可能只是单自由度的两指夹爪
