Gripper installation

Build
1

Hi everybody,

I am trying to install my new gripper but I have no action to the gripper at all. I have installed it using the instructions. I have tried the channel 1 and 3 and the buttons of the joystick 9 and 10 with and without shift function. I have checked that I have 15v to the power terminals…

Have you any idea what to try? Everything else is working like charm.

Thank you in advance!

@nmau,

I assume:

The yellow wire on the servo cable is plugged into either the bottom pin of aux servo channels 1 or 3

You have setup the following button functions:
servo_X_max_momentary (open while pressed)
servo_X_min_momentary (close while pressed)
where X is either 1 or 3

Did you try using your controller bumper buttons to control the gripper like BR did?

@tciii,

Yellow wire: ok

Buttons prameters: ok

I used buttons 9 and 10 on Logitech

Which are the bumper buttons?

I have just installed the gripper as well per instructions and got it to work twice before it stopped working. Didn’t get a chance to reboot the rov n software to see if it would start functoning again. Will try again today. Qgc is 3.2.4 rev 6

@tciii That link seems to be broken.
In my case, i got it to work but then it stopped. Same buttons, n no changes in between.

Hi guys, sorry you’re having some issues here.

First, I’d like to verify you have the most up-to-date firmware loaded: ArduSub 3.5.3.

Make sure that your button presses correlate to the correct action you want.

After that, please check that you are using the “servo_X_min/max_momentary” and not the other servo settings (min/max or min/max_toggle).

Please post a screenshot of your button settings if possible.

Thanks guys, you have turned my inspection class rov into a work class rov by fitting the Newton Gripper. Strong grip on it,so don’t be putting your fingers in to try it out.

Did you have to cut the head off the gripper to free yourself?

@SpatialGuy,

not exactly, but it is surprisingly a strong gripper…
