机器人触须传感器动态工作机理的研究
摘要
提出一种测量机器人触须与被测物体接触位置的新方法。在弹性触须的顶端加上适当的重物
增加触须的摆动惯性。当触须与物体发生接触后
触须停止摆动
触须的运动状态在与物体接触、非接触状态之间返复变化。信号采集系统以图形方式实时输出触须的振动波形
通过测量触须的振动频率
即可得出触须与物体的接触位置。
Abstract
A novel method to detect the contact point between the robot whisker and an measured object is suggested.By adding a proper mass at the top end of the whisker
the inertia of the whisker is enhanced.At the moment the whisker hits an object
it send the stop signal to the actuator.The motion phase of whisker will switch from contact to non-contact and vice verse.The signal acquisition system outputs the oscillation waveform at real-time in graphic formula method
by measuring the frequency of the whisker
the contact point between the robot whisker and an object can be decided.
