Comparison of shipbuilding crane manipulators.
| Category | Planar DOF | Main body | Workspace | Output trajectory length | End-effector height change difference |
|---|---|---|---|---|---|
| Traditional shipbuilding crane manipulator | 1 | A four-bar branch chain | Single trajectory | 23.1 m | 0.63 m |
| Hybrid shipbuilding crane manipulator | 2 | Two planar four-bar branch chains with a two-link sub-chain | Theoretically an infinite number of trajectories | 41.2 m | 26.7 m |
