人类从何时开始直立行走至今还没有找到确切的年代.然而直立行走解放了双手,并由此创造出光辉灿烂的人类文明。现在我们用解放的双手制作一个直立行走的车夫机器人. 电路原理 车夫机器人采用红外遥控方式。发射电路见图一。用双时基集成电路以及电阻、电容等组成两个典型的自激多谐振荡器,对红外光进行调制。当按钮AN按下时,电路接通,集成电路IC_(1-1)产生自激振荡,其⑤脚输出一个频率约为100Hz的方波信号,IC_(1-2)也产生自
The precise time since human beings began to walk upright has not yet been found, yet standing up emancipates both hands and creates a glorious human civilization. Now we use the liberated hands to make an upright walking coachman robot. The circuit theory The coachman robot uses infrared remote control. Transmission circuit shown in Figure one. With two time base integrated circuits and resistors, capacitors and other composed of two typical self-excited multivibrator, the infrared light modulation. When the button AN is pressed, the circuit is turned on, IC_ (1-1) generates self-excited oscillation, and its pin outputs a square wave signal with a frequency of about 100Hz. IC_ (1-2)
