非人灵长类动物上肢运动信号采集系统的构建与实验研究

Development and Evaluation of a Signal Acquisition System for the Movements of Upper Limbs in Nonhuman Primates

本文构建了一种用于非人灵长类动物的上肢运动信号采集系统。该系统包括上肢行为训练单元和肌电信号采集单元。通过对上肢行为训练单元的设计、加工制作并与肌电信号采集单元相结合,构建可操作性较强的非人灵长类动物上肢运动信号采集系统。该系统采用取食和饮水这两种日常行为动作来激励动物的上肢运动,为动物行为训练与运动信号采集提供了方便,并通过实验初步验证了该系统的有效性。与其他类似系统相比较,该系统在动物上肢肌电信号采集方面实用性更强,且适用于不同体积大小的非人灵长类动物。

In this paper, a signal acquisition system was designed and developed for the movements of upper limbs of nonhuman primates. The system included a behavior-training unit of upper limbs and a myoelectric signal-acquisition unit. Two daily behaviors of feeding and drinking were employed to stimulate the motions of animals’ upper limbs for the convenience of the behavior training and signal acquisition. The feasibility of the training system was confirmed by the preliminary experiments on monkeys. Compared with the traditional systems, the system proposed in this study was more convenient for the signal acquisition of the arms of animals, and more suitable for nonhuman primates with different sizes.
