摘要:

本文介绍了一种传感器集成自适应夹持器的设计与研制。自适应抓取器对于通过将手指缠绕在物体周围来抓取不同几何形状的物体是有用的。自适应抓持器中的指状物闭合序列可能由于任何不平衡的抓持力而导致物体从抓持器弹出,并且这种抓持失败对于轻质物体是常见的。所提出的夹持器的设计集中于确保对各种物体的稳定抓持,特别是对于轻质物体(例如,空塑料瓶)。致动机构基于可移动的滑轮和腱线,其确保一旦链接停止移动,其他链接继续移动并围绕物体缠绕。此外,优化用于改进自适应夹持器的设计。最后,通过在模拟环境PyBullet中执行对象抓取来进行验证,以便在常见的家用对象上执行简单的拾取和放置任务。

英文摘要:

In this paper, design and development of a sensor integrated adaptive gripper is presented. Adaptive grippers are useful for grasping objects of varied geometric shapes by wrapping fingers around the object. The finger closing sequence in adaptive grippers may lead to ejection of the object from the gripper due to any unbalanced grasping force and such grasp failure is common for lightweight objects. Designing of the proposed gripper is focused on ensuring stable grasp on a wide variety of objects, especially, for lightweight objects (e.g., empty plastic bottles). The actuation mechanism is based on movable pulleys and tendon wires which ensure that once a link stops moving, the other links continue to move and wrap around the object. Further, optimisation is used to improve the design of the adaptive gripper. Finally, validation is done by executing object grasping in a simulated environment PyBullet for simple pick and place tasks on common household objects.
