MyCobot 320 Socket

Note: raspberryPi version Only supports python3 The robotic arm that uses this class of premise has a server and has been turned on.

Use TCP/IP to control the robotic arm

1. Client

# demo
from pymycobot import MyCobot320Socket
# Port 9000 is used by default
mc = MyCobot320Socket("192.168.10.10",9000)

res = mc.get_angles()
print(res)

mc.send_angles([0,0,0,0,0,0],20)
...

2. Server

Server file is in the demo folder,For details, please check the Server_320.py file in the demo folder
