The general control of robot adopts the realization of raspberry pi 3B + treater, uses the stc51 control chip to control motor 201 on every organism, and independent power supply uses L298N motor drive board module to keep apart between control chip and the motor 201. The whole control network adopts a bus type topological structure and uses parallel ports for communication. For accurate control of the length of the telescopic assembly 2, an encoder can be arranged on the motor 201 to accurately feed back the number of rotation turns of the motor spindle to the stc51 control chip through the pulse number, so that the stroke change of the internal thread disc 203 is accurately calculated, and accurate control is realized. In terms of power supply, a 12V lithium battery is used for independently supplying power to a motion circuit where the motor 201 is located. And 5V lithium batteries are adopted for supplying power for the stc51 control chip.
