Design a module based robot system

The paper develops a module based robot system that has multiple functions. The core of these modules is HOLTEK microchip. The system contains many modules that are communication with master module using I2C interface. The master module is communication with main controller using RS232 interface. The main controller of the robot system is industry personal computer (IPC). It can display status of these modules on the monitor. The user can add or remove the sensor module in any time, and the main controller can acquires sensor signals from these modules on real-time. Finally, we integrate these modules in the robot system that executes some scenario for the user.
