Questions tagged [rcservo]

An rc or hobby servo is a closed-loop servomechanism, typically used in radio control model, hobby or small-scale robotics applications. It usually consists of a motor coupled to a sensor (e.g. potentiometer) for position feedback, typically using a high ratio gearbox.

Why are Servo Motors so noisy?

I was working on a project to make a bedside night light out of a stuffed butterfly or bird. I was making a mechanism to make the wings flap with a servo motor and some small gears. The servo motor was very loud as it moved. And this was whether or…

Connecting multiple different voltage servos to the same controller

I am using the Pololu Micro Serial Servo Controller connected to an Arduino and multiple other servos (4 total) to make a robot arm. Two of the four servos require 4-6 volts, while the other 2 require 7-10 volts, so I am planning on powering all…

Should a MG996R Servo's extreme position change over time?

This question is a follow on from my previous question, Overheating/Jamming MG996 servo. I have recently purchased my first ever servo, a cheap unbranded Chinese MG996R servo, for £3.20 on eBay. After mounting the servo horn and the bracket, I…

Do servos stop at their limits automatically?

I'm moving from controlling a robot arm with basic time based motors controlled using a raspberry pi and python to a more advanced robotic arm that has servos (e.g HS-425BB). With the time based motors I must constantly keep track of the arms…

Building A Servo Tester To Measure Peak/Stalled Amp Draw

Since finding data on stalled and in use under load (not free) amp draw for servos seems impossible, I want to build/create my own servo tester. All I really want to know is how much amps the servo is drawing at idle, at movement under load, and at…

measuring gears for servo motors

I'm quite new to mechanical engineering and not familiar with gears and motors. A few days ago, I bought a second-hand GWS servo motor for my project, and it didn't include gears. Can someone help me understand the correct measurement of my motor so…

Using hobby servo as axle

I am designing a pan-tilt camera mount using standard hobby servos. Many existing designs use the servo shaft as a revolute joint, as opposed to simply a torque producing element. As a revolute joint the servo mechanism is subject to different…

What would I need to control a DC servo using a 4-20ma linear analog signal?

I'm looking to find a way to operate a small servo using a 4-20ma linear analog signal generated by a PLC in an industrial setting. The purpose of this is to allow for automation for a task that currently is done by manually turning and adjusting a…

How can i tell if my HS-485HB Servo is an Increased Rotation servo?

Our Robotics Team (Go TuxedoPandas! ordered a mix of regular and "Increased Rotation" servos from Servo city. However,it appears only the outside packaging is marked. And only with a sticker. Is there any visual indication on the servo that it is…
