Robot PEARL MK2

  This robot, called PEARL MK2, is a series of robot PEARL. It has one IR receiver module, one RF module and three luminous intensity sensors and one IR object detector module. Power is provided from two small Ni-MH rechagable battery, 3.6V/70mAh. The used computer is PIC16C711/4MHz produced by microchip. And two small dc geared motors propelled PEARL MK2.  And It can drive in rough terrain with unique suspension system. The other feature of this robot is that it's modular in design. so every parts can be easily displaced and new parts  can be easily loaded on PEARL MK2. PEARL MK2 is a good mobile platform to experiment on various things about autonomous robot and collaboration of small robots.
