Use a motor to move a platform? Answered
I want to build a platform that I can use to mount lights on and make it to move in all directions by using a dynamo/motor/servo. Also the dynamo/motor/servo will be submerged in water at all times, so is there a possibility of making it watertight, if so how to do it?
Here are some designs that I did in order to show you that I have in mind.
