# motor controlled lazy susan

I'm trying to figure out an easy lazy susan setup. This is for video production, I want to be able to put an object on the platter and get a smooth consistent turn in order to shoot the object spinning. What would be the best way/parts to put this together?

Thanks

• get an old record player .... you'll get smooth 33rpm, 45rpm and if you are lucky 78rpm Commented Feb 21, 2019 at 3:08
• Welcome to Robotics Justin, but I'm afraid that Unbounded Design Questions are off-topic because there are many ways to solve any given design problem. We prefer practical, answerable questions based on actual problems that you face, so questions which ask for a list of approaches or a subjective recommendation on a method (for how to build something, how to accomplish something, what something is capable of, etc.) are off-topic.

You can design, or purchase, a simple rotary table. I have used Arrick robotics over the years, and they have a relatively turnkey system for $300 here: https://www.arrickrobotics.com/rt12.html If you are skilled at automation you could do this with a dc brushed motor and a platter, but it sounds from the way you ask your question that a turnkey system might better solve your problem. Here's the easiest setup with the lowest learning curve I can think of. What you can do is you can buy this robot car kit for$36: https://www.amazon.com/dp/B0794PWD7J/ref=psdc_2528074011_t1_B07KPZ8RSZ I am not affiliate with this seller in any way.

Then you just need to glue/double-sided tape the bottom of the lazy susan setup to the top of a car wheel and figure out a way to hide the car setup in your video.

You can modify the speed of the wheel by adjusting the sleep time and toggling the motor voltage from low to high in code. When a motor voltage is low, the wheel will not move. When it's high, it will move at max speed. In order to slow down the motor, you can sleep for a fraction of second, then move for a fraction of a second, then sleep again. The car kit will come with a manual to help you understand.

So now the more complex answer requiring more technical know-how:

• You will need a DC motor. A motor has a metal rod at the end so you need a shaft attachment so you can glue the lazy susan to the top of it. Make sure the DC motor has enough torque to spin your lazy susan and whatever is on it.
• You can control the DC motor with a circuit controlled by an NE555 timer chip. You can google NE555 timer DC motor setups and you'll get some circuit diagrams which you will have to build. Alternatively, you can buy and arduino/microprocessor to control your DC motor.

• You can use a servo motor as well such as the MG996R. Servo motors comes with servo horns which you can glue/double-sided tape the lazy susan directly to. You modify the servo motor to be able to spin continuously. Here's all the info you'll need if you go down that route: https://www.youtube.com/watch?v=J8atdmEqZsc
