摘要 大壁虎因其非结构环境中独特的运动能力已成为动物机器人领域研究的一个热点。大壁虎的四足运动特点是仿壁虎机器人研究的一个重要方向,为更好了解大壁虎运动时四肢肌肉的放电情况,制作了大壁虎肌电信号的在体无线采集与存储装置,该装置的大小为3.2 cm×2.5 cm×1 cm(长×宽×高),重量为12 g,系统能以1 kHz/s的采样率同时对来自5个通道的模拟信号连续采样2 h以上。通过信号发生器产生的稳定信号源对采集存储装置进行了验证,并对大壁虎附着于不同倾斜角度平面时四肢屈肌的肌电变化进行了初步研究,结果显示该装置可用于大壁虎不同状态的肌电采集记录,同时为其它动物生物电信号的采集与存储提供了有益借鉴。 Gekko gecko has become a hot research topic in the field of animal robot because of its unique motion characteristics in unstructured environment.Quadrupedal movement feature of gecko is an important direction in the research of biomimetic gecko robot. A device used for in vivo EMG acquisition and storage of Gekko gecko was made to investigate the firing pattern of corresponding muscles.The size of the device was 3.2 cm ×2.5 cm ×1 cm (L ×W ×H)with 12 g.Analog signals of five channels could be recorded with 1 kHz/s simultaneously for more than 2 h.The performance of the device was tested using a stable source from signal generator and changes of EMG signal in flexor muscles were initially studied on a plane changing with different angles.Results show that the device can be used in the EMG recording of Gekko gecko and it is expected to provide positive help to the acquisition and storage of bioelectric signal from other animals.
