Hello, I'd like to take a few posts to explain how my robot arm works before going into detail about using it. First, I'll explain the servo motors.
What Do They Do?
The servo motors handle all functions of the robot involving motion, bending the joints, closing the gripper, and rotating the base, all of these things use the servo motors.
What makes them different from normal motors?
Normal motors are very simple, electricity goes in, the motor turns. Servo motors are much more advanced. First, a signal comes in to the motor. This signal is composed of many quick electric charges traveling at a certain speed this speed tells the motor which position it should be in. The motor then rotates to that position, and continues to keep it's position if it some external force tries to change it.
So what does it do for the robot?
Using these servo motors, the arm can be controlled with a high degree of precision, and gives it the ability to keep it's position whilst under stress, such as when it's lifting an object.
