Steps
- Design the 5-DOF arm and measure each link length.
- Assemble the arm with the servos and brackets and wire them to the servo driver.
- Derive forward and inverse kinematics equations for the arm.
- Program a trajectory planner that moves the gripper smoothly between points.
- Run pick-and-place tests and measure position accuracy.
- Map the workspace and document the project for your portfolio.
