【Training Camp】Bionic Robot Dog

        The four-legged dog can move! It can move forward, backward, turn left, turn right and step!
 
     The following is a physical picture of Gouzi:
                                                                         

                                                                         

                       
 
        the project uses the Hi_3861 module of Chuanzhi Education, and the servo driver chip uses the PCA9685 chip. It is powered by Type-C and equipped with CH340C serial port chip. You can directly use Type-C to download files, and the download port has been led out, so you can use the TTL module to download. In this project, all pins of Hi_3861 have been lead out, and additional functions can be added, and all 16 PWM signals of PCA9685 have been lead out.
 
        The outer shell of Gouzi is all made of PCB structural boards. Currently, the surrounding shell and the dog's legs use boards within 10*10cm. The side panels are too long and are welded (very strong). The dog legs are directly connected with screws. The bottom plate and top plate have not been made yet.
 
        Gouzi's program and main data are open sourced on the Lichuang EDA open source platform. You can refer to the official routines.
 
        The main materials purchased are as follows:
                9 MG90S all-metal servos;
                1 Hi-3861 chip;
                1 PCA9685 chip;
 
Note: (1) In the PCB project, a fuse was added. Directly use solder to short-circuit;
       (2) The dog's legs are connected with screws. During the movement, they will become loose and can be fixed directly with glue;
       (3) The dog's body is cut from a PCB board, which is a bit ugly. ! ! !
