Suction pump: used for adsorbing objects
Suction pump, that is, vacuum adsorption pump, has a suction nozzle with one inlet and one outlet, and one exhaust nozzle. It has the advantages of simple structure, small size, convenient use, low noise, and good self-priming ability. By controlling the suction pump kit as the end effector of the robotic arm, it performs the function of absorbing objects.
Suction pump accessories: power cord x1, DuPont line x10, one-in-two-out connection line x1, Lego tech parts x several
When absorbing items: the air pump starts to pump air to absorb the items and then stops, and there will be no air leakage for a short time.
When putting down the item: the electronic valve is activated, the air release valve is opened, and the air enters the vacuum suction cup and separates from the sucked item.

Product installation tutorial text
Step 1: Female cable--the power cable end is connected to the port on the left side of the suction pump, the other end is connected to the outlet port of one input and two outlets, and the outlet end is connected to the power port of the robot arm, and the inlet end is connected to the power adapter.
Step 2: Connect the pin end of the DuPont line to the interface of the control motor and solenoid valve noted in the wiring diagram, and connect the other end to the G2, G5 pin (M5) 20, 21 pin (Pi) of the robotic arm.
Step 3: Fix the suction pump head to the end of the robot arm using LEGO Technic pieces.

Use the suction pump in the Python environment:
- 280 for M5 version:
from pymycobot.mycobot import MyCobot import time # Initialize a MyCobot object mc = MyCobot("COM3", 115200) # Turn on the suction pump, note: use one of pins 2 and 5 to control the switch of the suction pump def pump_on(): # Let bit 2 work mc.set_basic_output(2, 0) # Let bit 5 work #mc.set_basic_output(5, 0) # Stop suction pump def pump_off(): # Make position 2 stop working mc.set_basic_output(2, 1) # Make position 5 stop working #mc.set_basic_output(5, 1) pump_off() time.sleep(3) pump_on() time.sleep(3) pump_off() time.sleep(3)
- 280 for Pi version:
from pymycobot.mycobot import MyCobot from pymycobot import PI_PORT, PI_BAUD # When using the Raspberry Pi version of mycobot, you can refer to these two variables to initialize MyCobot import time import RPi.GPIO as GPIO # Initialize a MyCobot object mc = MyCobot(PI_PORT, PI_BAUD) # Initialize GPIO.setmode(GPIO.BCM) # Either pin 20/21 can control the switch of the suction pump. Note: the switch should use the same pin Foot control GPIO.setup(20, GPIO.OUT) #GPIO.setup(21, GPIO.OUT) # Turn on the suction pump def pump_on(): # open suction pump GPIO.output(20，0) #GPIO.output(21，0) # Stop suction pump def pump_off(): # Shut down the suction pump GPIO.output(20，1) #GPIO.output(21，1) pump_off() time.sleep(3) pump_on() time.sleep(3) pump_off() time.sleep(3)
