Topic: Pushing a buttom with servo (Read 1 time) previous topic - next topic

Browser

Hello,

i am trying to push a button with a servo. I need to push it with different pressures, so i have to control the pressure.

Any idea about can i do it?

Thanks.

Put a spring between the button and the pushrod from the servo.

I don't understand what you mean. I have tried with elastic to push it. It's the button of a spray

Are you sure the button responds to different pressures? 

What do you expect to happen?

What is happening?

Yes, of course, depend on the strength the painting is different.

I want to control from the arduino board the strength to press the spray.

I don't know how can i make something to push the spray's head (button)

A servo will turn a disk or arm.  Connect a stick to the disk or arm and when the disk or arm rotates it will push or pull the stick.  The stick is called a pushrod.

I assume then that the 'spray button' has a finite travel range that causes it to travel through full off, some variable spray to full spray? So it would seen that you just need to mechanically couple a servo arm such that you can manipulate the spray buttons travel range via the specific servo position. Your servo must also have a torque rating high enough to overcome the force/friction of the button and cause this travel, via the servo's basic torque rating and/or by using mechanical leverage linkage such that the desired travel and torque requirements are both met.
