信息矩阵
协方差矩阵的逆矩阵（也称精度矩阵），表示估计的确定性。在信息形式卡尔曼滤波器和因子图优化中，对于稀疏系统，使用信息矩阵更加自然——传感器观测增加信息（对信息矩阵的正定增量），而时间传播则减少信息。
Open 7-DoF arm, bimanual-ready. Ships from San Francisco with pilot data-collection packages from $2,500.
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.
Unbox, calibrate, and run your first autonomous walk. Includes ROS 2 bringup and teleop quickstart.
