Overview The project creates a robotic are that is made mostly from woods which is controlled by a PIC microcontroller and cloned PS/1 controller and with a lot of functionalities that any normal robotic arm can have. Explanation Since the arm will only be controlled by a PIC18F452, a simple design with as few moving parts as possible is important because using this PIC potentially limits the ability to control the arm with smooth movements. Also, one of the goals is to have grippers on the end that can grip trivial objects like a piece of paper or a pen/pencil. The PIC microcontroller has one control line feeding to each servo and it also connects to the RJ45 connector used for connecting input from the controller. Each servo has 3 wires coming out of it consisting of Power, Ground, and Signal (PWM). A 6V source is connected directly to Power & Ground and each Signal from each servo is tied to a unique pin on the PIC. The power circuit is just a 9V battery attached to the LM7895 with a 1uF capacitor attached to output & ground of the LM7895 to keep a steady 5VDC. Rest of the project
