Robot arm controlled with servo's and a PIC16F628A microcontroller

The PIC 16F628A controls the servo's with a pulse width from 1ms to 2ms every 20ms. The LCD and keypad are also controlled by the PIC. The keypad and the LCD share 4 outputs minimizing the total of I/O pins needed. The LCD shows the actual values of the servo's. The PIC is programmed that 20 individual robot positions are stepped through. Moving from 1 position to another position is done 1 increment at a time. This makes the robot arm very stable. The PIC can store the 20 individual positions of the robot arm in the internal EEPROM. This means that the positions are not lost.
