Pre-use Preparation

Before using the sample functions, please ensure that the following hardware and environment are complete:

• Hardware

  • MyCobot Pro 450 robot arm
  • Network cable (for connecting the robot arm to the computer)
  • Power adapter
  • Emergency stop switch (for safe operation)

• Software and Environment

  • Python 3.6 or later installed
  • The pymycobot library installed (using the pip install pymycobot terminal command)
  • Ensure that the MyCobot Pro 450 is properly powered on and in standby mode.
  • Note: The Pro 450 server automatically starts upon powering on; no manual operation is required.

• Network Configuration

  • MyCobot Pro 450 default IP address: 192.168.0.232
  • Default port number: 4500
  • Note: PC The local network card IP address must be set to the same network segment as the robot (e.g., 192.168.0.xxx, where xxx is a number between 2 and 254 and must not conflict with the robot).

  • Example:

    • Robot IP: 192.168.0.232
    • PC IP: 192.168.0.100
    • Subnet mask: 255.255.255.0

  • Verification: After completing the network configuration, execute the following command on the PC terminal. If data packets are successfully returned, the network connection is normal:

    ping 192.168.0.232
    

IO control

IO stands for data input and output. Our robot arm's Basic and Atom pins have multiple pins. This section mainly explains how to use the end-point IO to control the gripper.

Example Use

import time
from pymycobot import Pro450Client

# The default IP address is "192.168.0.232" and the default port number is 4500
pro450 = Pro450Client('192.168.0.232', 4500) # Client connection and communication

if pro450.is_power_on() !=1:
    pro450.power_on()  # Power on

# Open the gripper
def open_gripper():
    pro450.set_digital_output(1, 0) # Set pin 1 to a low level
    pro450.set_digital_output(2, 1) # Set pin 2 to a high level
    time.sleep(0.05)

# Close the gripper
def close_gripper():
    pro450.set_digital_output(1, 1) # Set pin 1 to a high level
    pro450.set_digital_output(2, 0) # Set pin 2 to a low level
    time.sleep(0.05)

# Repeat the gripper opening and closing twice
for i in range(2):
    open_gripper()
    time.sleep(3)
    close_gripper()
