The robotic arm has a steel design and it full assembled. There are 4 servo motors on the robotic arm. There are 3 high torque and high quality servo motors. For tutorial: https://youtu.be/eVz7mOJVvQc In this project, how to move the robotic arm with 4 potentiometers using an Arduino is shown. An ON / OFF switch for the air pump and a push button for the solenoid valve were used. Thus, the motor and valve can be manually intervened, which saves you power and current. In the coming days, we will do a "programmable automation arm" project with this robotic arm.
