Thank you everyone for the response!

Elisabeth, the removable link is going to be somewhere on the top of the robot.
Please dont confer about the removable link again, I have mentioned in the earlier post that its just the simple drawing of the robot, its not the actual image of the robot Im trying to build. So does simple drawing have to show everything whats on the robot?

Do you think anyone would build a machine that cannot be turned off and on? lol!
Dont worry, trust me I know what Im doing, okay?
