Hi Coppelia,

I want to do a two-stage grasping using Robotiq-85 gripper, can I control how much I close for Robotiq-85?
Thank you very much!

Perhaps depth info is disabled in the object properties of the vision sensor? Or objects are not renderable ? Hi fferri, Thank you! I changed the mode to blocking and now it works, is this normal? Another question is that for my image 512*512, the buffer length is also 512*512, this makes sense. Bu...

Hello Coppelia, I've taken an image from the top view to a table, and there are some cubes on the table. I want to get a pure 2d image only with their top faces appearing in the image, but with a perspective vision sensor their side faces appear as well (I need to use a perspective vision sensor). I...

Hello Coppelia,

I'm using the perspective vision sensor in simulation.
But I have some troubles with the depth information, can I extract the top layer image only in some ways?
Thank you very much!

Also, what should I do if I want the image to be saved as a gray scale value?
Thank you!

Hello Coppelia, I'd like to retrieve the image from a vision sensor in the scene and save it into some formats (I may need to look at it later, but these images are for training purposes use mostly). So, I'd like to know how to achieve this both using Python Remote API and in Lua Scripts (using getV...

Hello Coppelia, I found that lots of grippers fingertip has two parts: the first one is the fingertip itself, and the second part is the fingertip visible part under the first part. The first part is the pure shape, and the second part is the simple random shape. What's the point of this structure? ...

Hi Coppelia,

What are the ways to control a general gripper? What about Robotiq-85? Should I use torque control or velocity control?
Thank you!

Hello Coppelia,

I'd like to change the size of my arm and gripper, should I use scaling function or modify geometry? What's the difference between these two methods?
Thank you!

Hello Coppelia,

I got this message box when I tried to run a scene I created a week ago, but I don't remember I did any change to the simulation parameters. Is there anything I should look at or change?
Thank you very much!
