摘要:

在本文中,我们探讨了国家的最先进的欠驱动,顺应机器人抓手设计,通过查看他们的表现上的一个通用的抓取任务。从一个国家的最先进的开放式抓手设计开始,我们提出了设计修改,重要的是,评估所有的设计抓实验涉及选择的对象,导致3600对象抓手的相互作用。感兴趣的非计划的把握,而不是设计的通用性能,我们探讨的对象形状,姿态和方向相对于夹具和手指的数量和配置的影响。使用开环抓握,我们在试验中的成功率高达75%。研究结果表明,在运动约束和不确定性,不涉及抓取规划,2指欠驱动柔顺手优于更高的多指配置。据我们所知,这是第一个扩展的目标比较各种多指欠驱动手的设计下一般的抓持条件。

英文摘要:

In this paper we explore state-of-the-art underactuated, compliant robot gripper designs through looking at their performance on a generic grasping task. Starting from a state of the art open gripper design, we propose design modifications,and importantly, evaluate all designs on a grasping experiment involving a selection of objects resulting in 3600 object-gripper interactions. Interested in non-planned grasping but rather on a design's generic performance, we explore the influence of object shape, pose and orientation relative to the gripper and its finger number and configuration. Using open-loop grasps we achieved up to 75% success rate over our trials. The results indicate and support that under motion constraints and uncertainties and without involving grasp planning, a 2-fingered underactuated compliant hand outperforms higher multi-fingered configurations. To our knowledge this is the first extended objective comparison of various multi-fingered underactuated hand designs under generic grasping conditions.
