Hi schittampalli ,

1. As long as you set the search points as far apart as possible, you may not need to add more points to capture the roll and pitch of the part.

2. You can mix different search frames. For example, you can mix UTOOL[-Z] with UFRAME[X,Y,Z] for additional search points.

Hope it helps.

dha Thank you, sir! I am currently trying to reconnect the robot to our local network. Hopefully it will be relatively straight forward.

Here is a basic Karel program for backing up everything in the Memory Card (MC) to the USB stick (UD1)

I find it annoying to have to remove the Memory Card to back up all subfolders.

This program works up to 3 levels of sub folders during testing. There is a risk of Stack Overflow with deeper levels.

A new folder in UD1 is created to store contents in MC every time the program is executed (up to 9 folders daily).

Disclaimer:
I am learning the Karel program as I go, so please use it at your own risk.

All feedback regarding programming is welcome.

SkyeFire You have a very good point. A local network would be as far as I am willing to get the robot connected as well.

R47 Thank you for the suggestion. Running it with a Macro is a very logical step. I will most likely go this route.

SkyeFire I wish our Robot was connected to the internet, but it is not at the moment. Thank you for the suggestion, it will come in handy one day.

First of all, I want to thank you all for the wonderful community.

I recently wrote a Karel program to backup all files (including subfolders) on MC to a new folder in UD1.

If there are any interests, I will share the file once I have the chance to test it.

My question is:

Is there a way to run the Karel program without having to hold the Deadman switch and the shift key?

I am currently calling the backup program from a TP program.
Using the RUN command allows me to release the shift key, but I am hoping to be able to run the backup program even in Auto mode.
One idea comes to mind is to use a digital output to trigger the Karel program. Is there a more straightforward way to do so?

Thank you in advance.

Hi everyone,

I am thinking about mounting a DSLR onto the robot arm for 3D scanning larger parts.

Has anyone had the experience of doing so? If so, are there any particular things to watch out for?

Best,
Frank

Nation Thank you for the reply. You are such a wizard with the post processor. I am not sure if my linear algebra is still up to the task of programming a CAM routing profile.

TitusLepic Thank you for the reply. I completely understand. It is one of those nice to have but non-urgent projects.

Hi TitusLepic,

I am in the same boat. The other day I was wondering what could be the secondary uses of the robot. Being able to carve foam out for the mold shop would be very cool. Did you ever find the appropriate Cam program for it?

Best,

Frank

Nation that is what I have come to accept. Appreciate your reply as always!

Hi Nation I am trying to run the program and it is also showing that the program can not find version.dg (I did an all of the above backup of the MD) I tried looking for the file on the robot itself and I don't seem to be able to find the file there either. Is there a way for me to bypass this step and enter the values manually?

Hi fellow programmers,

It seems to be a silly question but I can't get it to work.

I can copy everything file in the memory card to the USB that is not in a sub folder, but is there a way to copy the entire memory card (including all sub folders) to the USB?

Thanks in advance.

Best,

Frank

Appreciate it too massula

gwallee This looks like a very interesting tool. Thank you for sharing it, but the link seems to be dead. Could you please upload it again?

This is a really cool. I understand the overview that you provided, but will need to brush up my linear algebra to understand how the nuts and bolts are actually put together. Thank you for sharing it with us.

Thank you TitusLepic . Your patience and generosity is greatly appreciated. I will try to reinstall the controller with the same options.

TitusLepic This is exactly what I am looking for. But somehow I can't find Color by Axis limit option. I see Color by Speed, Acceleration, Orientation and IO state only.

Nation Thank you for the reply. I understand the concept and it is quite clever. To write the Karel program on this would be a fun challenge. The position converter definitely comes in handy!

I have been programming a robot that uses a laser to calibrate frame shifts, so the user frame differ slightly for each job.

When I do the test runs everything is fine, but sometimes during the production run a axis limit would be reached and the robot would pause.

Is there a way, either with the teach pedant or using Roboguide to check that all points are not close to axis limits?

One way I can think of is to reduce the axis limits while programming, then change them back to normal for production runs. But that will require me to go through all programs again.

Thank you for your advice in advance.
