Advanced Robotic Pick And Place Arm And Hand System projects main idea is to develop a application which can handle tough tasks like bomb disposing and many other situations where human being can not reach. 

For a robot it is obviously important that it can operate from batteries. Since the microcontroller runs with 5V the motors also must work with 3-5V. They must also not take too much current as the batteries and the control circuit will get too big and heavy. For this design we use an integrated motor driver chip, called l293d. The l293d motor driver chip can drive peak. All the logic is implemented in the software. That means by changing the software you can change almost everything as you like. 

The good thing about this robot is that the hardware is somehow generic: It’s basically 2 motors attached to a microcontroller.
