Adaptive gripper: Used for gripping objects
Introduction
- The gripper is a robot component that can achieve functions similar to human hands. It has the advantages of complex structure, firm gripping of objects, not easy to fall, and easy operation. The gripper kit includes gripper accessories and Lego technology parts. The end effector of the robot arm is controlled by a programmable system to achieve functions such as object gripping and multi-point positioning.
Working principle
- Driven by a motor, the gripper's finger surface makes linear reciprocating motion to achieve opening or closing movements. The acceleration and deceleration of the electric gripper can be controlled, the impact on the workpiece can be minimized, the positioning point can be controlled, and the clamping can be controlled.
Applicable objects
- Small cubes
- Small balls
- Long objects
Installation and use
- Check whether the accessories package is complete: Lego connectors, grippers with connecting wires, and connecting wire extension wires
Gripper installation:
Structural installation
Insert the Lego connector into the socket reserved for the gripper. You can choose two different directions for installation as needed:
Align the gripper with the connector inserted with the socket at the end of the robot arm and insert it:
Electrical connection
Connect the extension wire to the gripper:
Insert the robot arm control interface:
Python programming control
- M5 version:
from pymycobot.mycobot import MyCobot
import time
# Initialize a MyCobot object
mc = MyCobot("COM3", 115200)
# Control the gripper to open-close-open
mc.set_gripper_state(0, 80)
time.sleep(3)
mc.set_gripper_state(1, 80)
time.sleep(3)
mc.set_gripper_state(0, 80)
time.sleep(3)
- Pi version:
from pymycobot.mycobot import MyCobot
from pymycobot import PI_PORT, PI_BAUD # When using the Raspberry Pi version of mycobot, you can reference these two variables to initialize MyCobot
import time
# Initialize a MyCobot object
mc = MyCobot(PI_PORT, PI_BAUD)
# Control gripper open-close-open
mc.set_gripper_state(0, 80)
time.sleep(3)
mc.set_gripper_state(1, 80)
time.sleep(3)
mc.set_gripper_state(0, 80)
time.sleep(3)
