When you have built M.A.X.™. as a robot, you will want to make sure you are in Robot mode. On the back of the MeccaBrain™, there is a switch that allows you to put M.A.X.™ in Robot or Drone mode. Robot mode tells the MeccaBrain™ to activate all of the interactive features of your robot. Drone mode tells the MeccaBrain™ to activate select features of your build. Use the Drone mode when you want to build something other than a robot.
