It is shown here that both reachable and dexterous workspaces of the redundant manipulators are significantly larger compared to non-redundant manipulators of the same size. As a result, kinematic redundancy can be an appropriate solution for improving parallel manipulators’ characteristics.作者: 過剩 時(shí)間: 2025-3-30 07:21 作者: Confess 時(shí)間: 2025-3-30 10:01
