Robotics experiment with PIC microcontroller l 25
Robo-PICA robotic kit is controlled by the RBX-877 V2.0 (PIC16F887 Robot Experi-
ment board). The main microcontroller is the PIC16F887. Figure 2-1 shows operating dia-
gram of RBX-877 board. In this chapter will present the operation of RBX-877 board and
some example experiment. Builders must read and test all experiments for building and
programming the robot in next chapter.
