"""[summary]
|
|
This file obtains the joint angle of the manipulator in ROS,
|
|
and then sends it directly to the real manipulator using `pymycobot` API.
|
|
This file is [slider_control.launch] related script.
|
|
Passable parameters:
|
|
port: serial prot string. Defaults is '/dev/ttyUSB0'
|
|
baud: serial prot baudrate. Defaults is 115200.
