my robot idea is to make a wor

my robot idea is to make a working arm (similar to the robot helping hand that was in the email), i have already made 5 or 6 paper straw EZ-Robots, but I only have one controller and it is v3, I am constantly running out of servos and i really could use another controller. I especially want to get more of my straw robots onto the EZ-Robot youtube channel. Thanks MrRobotGuy (my youtube)
