Detect motion stop

Hello.
I have a machine that I need to personally check if two of its mechanical components are moving.

One component moves up and down
Another to the sides.

Is there a way to detect when these movements stop?

Hello

You might use a cam.

@xdukezbr Surely yes, but the solution depends on the type of mechanism in question. Could you be more specific?

Hello, thanks for the reply.
So it's a "pin" of a machine and a "claw".

When I turn the machine off, the "pin" and "jaw" obviously stop moving.

But it happens that the machine is turned on and the "pin" or the "claw" is stopped, then it is necessary to restart.

Hello, thanks for the reply.
I have enough machine to look at.

Using a camera would keep me from walking around, but I would still have to see several different cameras.

I wanted a system that could alert me when motion stopped so I didn't have to look in person or stare at the camera.

Maybe you could use laser/IR barriers, or (if speed of movement allows) laser distance meters.

If end of travel switch is not hit within cycle time of machine, then machine has stopped.

Draw a picture.

A laser beam and a phototransistor.

Assuming some kind of motor/actuator/servo is the mechanical link for each, simply monitor the current to each and then do whatever if a certain condition exists........

Can youn show us a photo of the machine? Detection is easy but depends on the environment, the size and material of the pin and claw , etc.
