How to program the Arduino to make the servo do variable speed movement?

KlausST said:

A servo motor simulation .... only you know what this means.
They are very similar .... to what?
As long as the replacement servo ... I have no idea
that formal robot can also operate in this way ... what robot? Which way?

But I could be wrong and I might need more help from you. .... Without clear information I can't help.

I have no idea what you want to achieve.

I did have an idea whether a quadruped robot could do variable speed motion, but I was almost completely ignorant about robots, so I bought the servo pretending to be the quadruped of the robot, and if I could control the servo to do variable speed motion, it would be the same as being able to control the variable speed motion of a quadruped robot.

Why servos in a quadcopter?

Now I recognize I was wrong in asuming you want to build a quadcopter.

My ability is not enough to build a quadruped robot, I will search and learn how the servo works on the internet, I am very sorry to bother you so long.

Thanks for your enthusiastic reply too, maybe I need to learn a bit about how the servo works from the basics.

Nothing can beat that!!


Try this one as a start.

Yes, I will, thank you very much!

I have experience with servos for a model airplane. Control pulses vary from 1 to 2 milliSec in length. The controller sends about 50 per second. The arm responds about as quickly as you move the joystick.

If you want the arm to take a certain length of time to move to a different position, change pulse lengths in tiny increments (say by a few millionths of a second) during the desired timeframe. It's identical to the effect if we were to move the joystick slowly.

I bought an Arduino controller online and bought several bus servos to make a quadruped robot. I want to use Arduino to control the servo variable speed movement and can show it on the LCD display in real-time.
I found that the control program given by the store can only realize the uniform motion of the servo mode, and I would like to ask how to program the algorithm to realize the variable speed motion of the servo bionic.

You can use a driver board that has all kinds of controls for the servo.
