steps:

To build a robotic arm, it is important to follow a systematic approach. Here are the steps involved, starting with 3D printing the components of the arm:

3D Printing Components: Begin by designing and 3D printing the necessary components of the robotic arm. This includes the arm segments, joints, gripper, and any other required parts. Ensure that the printed components are accurate, sturdy, and fit together correctly.

Assembling the Arm: Once the printed components are ready, proceed with assembling the robotic arm. Follow the design specifications and carefully connect the arm segments and joints. Use appropriate fasteners, such as screws or bolts, to secure the components in place. Pay attention to the range of motion and ensure smooth movement between the arm segments.

Use appropriate fasteners, such as screws or bolts, to secure the components in place. Pay attention to the range of motion and ensure smooth movement between the arm segments.

Testing Stepper Motors: With the arm assembled, it is essential to test each stepper motor individually. Connect one stepper motor at a time to the appropriate driver board and power supply. Write a simple Arduino code to control the motor's movement, such as rotating it by a certain angle or controlling its speed. Verify that each motor operates as expected and can move smoothly and accurately.
