   I've worked with hexapods before and they really suck a LOT of power.   
   I used 4 double AAs to run the 12 servos and a separate 9 V to run the   
   micro controller. The batteries had to be changed frequently and the   
   operational time of the robot was not great.   
   If it is a power problem try a AC to DC converter to the run the   
   servos.   
   There really is no way around the power problem other than using a   
   more efficient system (i.e. lighter robot, better batteries etc)
