的阻值为30Ω,电流表的量程为0～200mA,电压表的量程为0～9V.湿敏电阻R的阻值随湿度RH变化的关系图象如图丙所示,其阻值最大为120Ω(图中未画出)。 则在电路安全工作的前提下,请计算出: (1)当电流表的示数为0.2A时,R接入电路中的阻值? (2)当电压表示数为9V时,通过R0的电流? (3)装置能监测湿度最大值...
A new visual control method for the end-effector of a robot to approach an object is proposed in this paper, which consists of tracking, approaching and decision part. Two uncalibrated cameras are employed. One is for track the object in its image space. Another is for approach the object ...
