Battery Pack
Don’t install batteries yet.
Power is supplied to ARobot using a battery pack that contains 8 AA size batteries. Locate the battery
cable which has a batter snap on one end and a 2-pin MTA connector on the other. Pin 1 has the red
wire and is +12 volts, Pin 2 is the black wire and is ground (0 volts). Plug the MTA connector from the
battery cable onto the power connector on the controller board. Route the other end through a nearby
hole in the robot body. Place Velcro on the battery holder and on the robot body – make sure the cable
can reach. Connect the cable and mount the battery holder.
