协方差矩阵
一个方阵，编码随机向量各元素的方差和相关性。在机器人学中，协方差矩阵出现在：卡尔曼滤波器（状态不确定性）、高斯过程模型、测量噪声模型和位姿不确定性表示中。对角线包含各个方差；非对角线元素表示相关性。

90+ platforms — humanoids, arms, quadrupeds, dexterous hands, and teleoperation kits. In-stock hardware ships in 48 hours.
Hardware-synced demonstrations for VLA and imitation learning. Download in LeRobot, HDF5, or RLDS format.
From first arm on the bench to a policy that survives a real workcell — the Robotics Center pipeline in three steps.
Low-latency data-collection glove for dexterous manipulation. From $5,500, ships from San Francisco.
