320M5 handle remote control case

Function description: Use the game controller to control the robot to perform coordinate movement and suction pump switch

1 Suction pump installation

First install the suction pump to the end of the robot arm

Then connect the suction pump control box line to the base IO of the robot arm

2 Suction pump test

from pymycobot import MyCobot,utils
import time
arm=MyCobot(utils.get_port_list()[0])
for i in range(1):
    arm.set_basic_output(1,0)#Turn on the suction pump
    time.sleep(2)
    arm.set_basic_output(1,1)#Turn off the suction pump
    time.sleep(2)

3 Controller function description

Note: The controller needs to be purchased separately, please consult the official customer service for details

Note: Some handle buttons are not used, so they will not have any effect on the robot arm

4 Installation of handle dependency library

Open the terminal and enter the following command to install the handle driver library

pip install pygame

5 Preparation

Adjust the robot arm to the posture shown in the figure below. There should be no debris around the robot arm to avoid collision

Note that the screen of the robot arm seat should display ok

Turn on the switch of the handle

Note whether the MODE LED of the handle is on

Note: Only MODE The LED lights up before you can control the robot arm. If the handle is not used for a long time, it will enter the standby state. You can press the START button of the handle to activate it.
