用语音控制的腱驱动仿生手,7秒完成全指屈曲,稳定抓握各类物体。

Development of a Voice-Controlled Tendon-Driven Bionic Hand

  • 基于肌腱传动和舵机驱动,通过Arduino实现手势精准控制。
  • 全指屈曲耗时7-8秒,多次循环无精度丢失,抓握稳定可靠。
  • 支持语音指令,适合残障人士辅助设备研究与应用。

手部损伤会严重影响日常活动能力,因此设计稳定可控的辅助装置是重要研究方向。本文提出一种自动化仿生手,通过简化高效的腱驱动机制实现手指协调运动。系统采用舵机作为执行机构,结合角度校准实现手指动作控制,由基于Arduino的微控制器编程执行开手、握拳、捏取及半屈曲等预设手势。系统配备语音命令接口,通过蓝牙收发架构接收指令,可即时转化为手指动作。实验测试表明,所有手指顺序完全屈曲约需7-8秒;在多次驱动循环中,动作重复性好,无明显张力或控制精度损失;能稳定抓握不同形状与尺寸的物体,显示手指间协调一致。结果表明,该系统具备可预测、稳定的控制行为,且机械与控制架构简洁高效。

原文摘要 · Abstract (English)

The impairment of the hands can seriously affect the abilities of every individual to perform the every-day activity, so the design of stable and controllable support devices is a significant field of study. This paper is about the design and implementation of an automated bionic hand which is dedicated to the coordinated finger movement through the simplified and efficient actuation mechanism. The method that the proposed system was designed on is the tendon-based method whereby the servo motors generate the movement of the fingers, with assistance of the angular control which is calibrated. An actuation is controlled by a microcontroller that will be programmed by use of an Arduino-based microcontroller to carry out programmed gestures that include open hand, fist, pinch and half flexion. It has an interface that is voice command enabled to make it easy to interact with a Bluetooth based sender receiver architecture which offers an option of executing trained commands which are immediately converted to finger actions. To explore the motions behavior, finger coordination and control response to the input, the behavior of the experiment system is tested. The actuation of the fingers was found to take a total of about 7-8 seconds to achieve full flexion of all fingers in a sequence. The system showed repetitive and constant motion throughout several actuation cycles without loss of any apparent tension or precision of control. There was a stable grasp of objects of different shapes and sizes, which implied consistent coordination between the fingers. These findings indicate that the proposed system offers predictable and steady control behavior and has a simple and efficient mechanical and control architecture.
