收藏资源简介：
SemanticVLA TraceX 240K Bridge 是TraceX-240K轨迹标注语料库的Bridge组件，属于SemanticVLA项目。该数据集是基于LeRobot v3.0重新打包的BridgeData V2 · WidowX数据集，其核心特点是包含密集的每帧末端执行器轨迹标签（trace labels），这些标签直接存储在每个帧行中。数据集包含53,192个episodes和1,999,410帧，帧率为5 FPS，使用WidowX机器人，原始数据源为BridgeData V2 (v1.0.0)。轨迹标签包括trace.x和trace.y，表示归一化图像空间坐标（范围[0, 100]），用于标注每帧中末端执行器的位置。
The Bridge component of TraceX-240K — the trace-annotated trajectory corpus introduced in SemanticVLA. This package is a LeRobot v3.0 repack of BridgeData V2 · WidowX with dense per-frame end-effector trace labels stored directly in every frame row. It contains 53,192 episodes and 1,999,410 frames at 5 FPS, using the WidowX robot, with the original source dataset being BridgeData V2 (v1.0.0). The trace labels include trace.x and trace.y, representing normalized image-space coordinates on a [0, 100] scale for end-effector position annotation per frame.
