Steps
- Assemble the 6-axis arm with servos and gripper and wire them to the servo driver.
- Measure link lengths and set up the arm's kinematic model.
- Program inverse kinematics to calculate joint angles for any gripper position.
- Test positioning accuracy at several target points.
- Program a pick-and-place routine that moves objects between locations.
- Film the demo and document the math and build for your portfolio.
