I have published 10 videos to make a video tutorial series about “How to make robotic arm” . Started about servo motor as actuator to how to make 4 DOF Arduino controlled robotic arm. Here is the link of all tutorials:
Video1: About Actuator, Basic structure of servomotor and working principle and how to control from Arduino
https://www.youtube.com/watch?v=XiGcBLWpcF0
Video2: How to use powerful servo motor. Und ....... derstand the current consumption to select right power supply otherwise it may reset the system due to voltage drop for over load.
https://www.youtube.com/watch?v=eg4C5iIusZQ&t=267s
Video3: How to use a simple sensor to control the servo rotation via Arduino. I also tired to explain the schematic and BOM are all you need to make a circuit board. You no need to see and copy an assembled board.
https://www.youtube.com/watch?v=Y5Jqxbu-RKo&t=7s
Video4: How to make a 1 DOF arm which is controlled via a sensor mounted on human body. Suppose the sensor is on your elbow so by moving your and you can control the elbow of the robot.

Video5: Basic structure of a robotic arm and definition of degrees of freedom (DOF). Where I also explained about robotic grippers. And how they are used for different application using the same arm. Here is one simple wire guided robotic gripper.

Video6: A geared servo-based home made gripper. The gears are handmade from MDF/Wood

Video7: Then we found the issues with the above gripper and modified it to a parallel jaw Arduino controlled gripper for better grip.

Video7: We soon understand that its not an easy task to grip different object properly so me made one miniature universal servo gripper and it performed well.

Using all the knowledge and skill we got from above projects we made a 4DOF robotic arm
It’s A to Z process were explained in two following parts
Video8: Part1: https://www.youtube.com/watch?v=08Znj2TJLDs&t=51s
Video9: Part2: https://www.youtube.com/watch?v=op48_EU2KOg&t=2s
Future improvement: Store the task in EEPROM and repeat multiple times.
Connected the control pot to make one joy stick to improve the control accuracy.
