This paper presents the kinematic design of a single degree-of-freedom exoskeleton mechanism: a planar eight-bar mechanism for finger curling. The mechanism is part of a finger-thumb robotic device for hand therapy that will allow users to practice key pinch grip and finger-thumb opposition, allowing discrete control inputs for playing notes on a musical gaming interface. This approach uses the mechanism to generate the desired grasping trajectory rather than actuating the joints of the fingers and thumb independently. In addition, the mechanism is confined to the back of the hand, so as to allow sensory input into the palm of the hand, minimal size and apparent inertia, and the possibility of placing multiple mechanisms side-by-side to allow control of individual fingers.
一种用于手指卷曲的平面八杆机构。该机构是一种用于手部治疗的手指-拇指机器人设备的一部分,它将允许用户练习关键捏握和手指-拇指对掌动作,能够在音乐游戏界面上进行离散控制输入以弹奏音符。这种方法利用该机构生成所需的抓握轨迹,而不是独立驱动手指和拇指的关节。此外,该机构限制在手背,以便能够向手掌提供感觉输入、尺寸最小且惯性不明显,并且可以并排放置多个机构以实现对各个手指的控制。
