Mechanical Gripper for Robot Arm with MG996R Servo

Components Required:

1. DIY Kit
2. Arduino Uno
3. Jumpers

Software Required:

1. Arduino IDE

In this tutorial, we will learn how to make a mechanical claw for your robotic arm. We are using the MG99R metal servo, to control the claw, which is perfect for handling rigorous tasks. Weighing only 60 grams, and providing a maximum angular spacing of 50mm (5cm), this can be used for a wide variety of applications.

Step wise Assembly:

Upload and Run the Code

Connect the Arduino to the computer using the USB Cable.

Open Arduino IDE software

Select the appropriate board under Tools > Board

Select the appropriate Serial Port under Tools > Port

Here is an example code that you can upload. It will open and close the claw periodically after 1 second. Calibrate the open and close angles of the mechanical claw by changing the appropriate angles in OpenClaw() and CloseClaw() functions.
