Hand gesture based mobile robot control using PIC microcontroller

In the recent days gesture controlled devices are getting more attention. There are different types of gesture controlling techniques. In this work, gesture of the user controls the movement of the mobile robot. The developed system is classified into gesture unit and mobile robot unit. The gesture unit consists of PIC microcontroller which monitors the movement of fingers and transmits the corresponding control signal to the mobile robot unit. The mobile robot unit also consists of PIC microcontroller for controlling the movement of mobile robots. In the gesture unit PIC microcontroller is assisted by flex sensors and XBee-S1 for reading gestures. Similarly in mobile robot unit PIC microcontroller is assisted by peripherals like XBee-S1 and L293DNE. Both the units are powered up by separate battery source. This proposed system is developed at low cost with better efficiency. It can be implemented in many other applications such as holding the speakers to assist dumb people, toys etc.
