A Versatile PIC16F876A Based Robot

Design ¬† Summary: Our¬†group¬†designed ¬†and ¬†manufactured¬†a ¬†miniature ¬†robotic ¬†vehicle ¬†that ¬†conquers ¬†various terrains. ¬†¬† The ¬†vehicle ¬†was¬†designed ¬†with ¬†a ¬†track¬†system ¬†which¬†is ¬†powered ¬†by ¬†two ¬†DC¬†motors. The ¬†motors ¬† use¬†a ¬†Quadruple¬†half ¬†H ‚ÄźDriver¬†in ¬†order¬†to ¬†drive¬†the ¬†motors ¬†in ¬†both ¬†directions.¬†¬† The track¬†system ¬†incorporates¬†a ¬†four ¬†bar¬†linkage ¬†for¬†each ¬†tread. ¬†¬† These¬†two ¬†linkages ¬†allow¬†each ¬†side to ¬†be¬†independently ¬†raised ¬†which¬†gives¬†the ¬†robot¬†multiple¬†configurations.¬†¬†
