机器人触须传感器的设计 总被引:5,自引:4,他引:5
提出了一种利用触须来识别物体表面轮廓的新方法。传感器采用了二维PSD作为敏感元件,实时地测量由于与物体接触在触须根部所产生的微小位移量。介绍了机器人触须传感器具体的结构及工作原理。由实验数据可知,触须根部位移量的大小与接触的距离成反比,且距离越近位移量变化的速度越快。由此可获得待测物体的位置、距离、角度等信息。 相似文献

啮齿类动物利用触须能够很好地识别外部对象的轮廓,为移动机器人识别被测物体提供了新的思路。借鉴啮齿动物触须的毛囊结构,设计了一种新型触须传感器,传感器采用二维PSD作为敏感元件。此传感器安装在移动机器人上,通过测量触须根部产生的微小位移量,来识别被测物体的外形轮廓。完成了圆柱体和棱柱体样件的对比实验,证明利用该触须传感器移动机器人能够识别出外部对象的轮廓。 相似文献

For the control of a dynamic mobile robot, the attitude in gravity space is an important state of the robot. Usually, the attitude is difficult to detect by simply using the signals from sensors. For example, an external sensor contacting the ground suffers disturbances from the roughness of the ground; the integration of a gyroscope signal has the problem of drift; an inclination sensor does not indicate the direction of gravity when acceleration exists. To solve these problems, we propose a control method in which the attitude of a mobile robot is estimated by an observer considering the robot dynamics and using only the information obtained by internal sensors. We applied this method to a wheeled inverted pendulum as an example of a dynamic mobile robot. The estimation of the attitude was made with good accuracy using the signals from the rate gyroscope and the motor encoder, and the control of stable running of the pendulum on a flat level plane worked successfully. We also realized the running control of a pendulum on an unknown rough road using the estimation of the slope gradient made by the observer. Thus, the effectiveness of the proposed method was demonstrated experimentally. 相似文献
