The data describe an approximately 0.9 m-wide corridor experiment and include the target trajectory, real motion trajectory, tractor and trailer states, taut/slack cable-mode transitions, velocity profiles, and tracking states. The trajectory is generated using hybrid dynamics modeling, front-end hybrid search, and back-end nonlinear trajectory optimization, and is validated on a Unitree A1 quadruped robot with a customized cable-trailer. The dataset can be used to reproduce the target trajectory, real trajectory, and tracking-state curves in Fig. 8, and to evaluate feasibility, safety, and dynamic executability of hybrid-mode trajectory planning in narrow environments.
