For a model learning from visual observations and actions, camera fit and control semantics need to be assessed together. Describe the views available at deployment and the action interface the model will drive. A visually rich collection may still be unsuitable if its action representation or timing cannot be interpreted for your project.
Match the available visual inputs
Specify fixed cameras, wrist views, depth, or other streams only where needed. Record camera placement, image transformations, and any calibration information required by the model. A dataset containing an overhead view does not establish that a wrist-camera policy will receive the same task evidence or object visibility.
Explain the action target
State whether the learner predicts joint targets, end-effector motion, gripper commands, or another representation. Document absolute versus relative values, units, reference frames, and how commands are applied. Include the controller configuration relevant to interpretation rather than treating every same-length action vector as interchangeable.
Review temporal association
Define how observations are paired with issued actions and measured feedback. Sensors and controllers may run at different rates, so ask what resampling or selection produced the delivered steps. Inspect brief movements and contact transitions, and retain raw timing references where available so the pairing can be audited.
Keep transformations reproducible
Image resizing, state normalization, action conversion, and clipping can change what a model learns. Record those operations and identify original versus derived fields. Review a representative episode through the proposed loading process before expanding an inquiry. Availability, technical fit, and the proposed use scope remain separate questions for the actual source. Include explicit handling for unavailable views or state fields in the proposed input specification.
