9g Continuous Rotation Micro Servo

It works great

I originally purchased these from Amazon, being a novice to the tech scene. When I received that order, they were not what I needed. I was directed to RobotShop.com by a more experienced tech person and was more than thankful. The RobotShop.com site helped me get exactly what I needed, and the shipment came very quickly. I will be using them again for future purchases.

Tiny and speedy, but impossible to get a steady stop position set, it drifts all over the place. I am going to have to add a relay to shut off power to the servo when I want a full stop out of it.

I've modified a lot of servos for continuous rotation over the years... they make great motors for little robots. However, the process is time consuming and when you make a mistake, it's like blowing your nose in a five-dollar bill. Being able to buy them as continuous rotation servos is awesome - having a trim is even more awesome-er. Keep in mind that this servo is constructed with nylon gears, an abrupt stall may destroy the servo.

Used these for a robotics and Arduino class with 5th through 8th graders. Didn't really have the time or financial leeway to go the motor controller route. All went well. I'm glad these exist, I'm glad I got em' and I will do it again.
