the opposite point you want to move)<br \/>\n&#8211; Better gyroscopic control because the balls can be spun up faster both around the track (limited by the motor torque ability) and spinning (versus motion around the track) around the back side.<br \/>\n&#8211; Also directly available<br \/>\n&#8211; Multiple balls are possible, but limited<br \/>\n&#8211; Easy to manufacture<\/p>\n<p
