AI Thread Summary
Fanuc robots, particularly those with RJ 2 or 3 controllers, are commonly used in MIG welding applications. Users often need to make minor adjustments to the robot's point positions, typically achieved by switching to the "Tool" coordinate system and manually adjusting the position at a low speed. However, this method lacks precision. There is a desire for a more accurate way to command the robot to move specific distances, such as ".3mm in the positive direction along the Y Axis." While searching for solutions online can be challenging, one user discovered a patent application for software that could potentially facilitate this precise movement.

Has anyone here worked with Fanuc robots? At my shop, we use RJ 2 or 3 controllers on all of our MIG welders. I sometimes have to make small moves in the robot's point positions. This is generally done by putting the robot's coordinate system in "Tool", finding the axis I need, and then setting the speed to 2 or 3 %, and "bumping" the directional button a couple times until the location looks about right. Obviously, this process is not very precise. I'm wondering if there isn't a way to just tell the bot that I need to go ".3mm in the positive direction along the Y Axis"?

I'm looking around online for instructions on Fanc RJ2/3 controllers, but this question is too complex for any of the search engines I use to find an answer on the net. I could look it up in the manual, but that's at the shop and when I'm there I don't have time to read! Any help would be greatly appreciated.

LURCH did you end up figuring this out? The Fanuc Robot looks pretty neat!
 
OK; after some pretty extensive searching, I did find an answder of sorts. Clusty dug up a link to a patent application for a software packet that would do what I want. I guess that settles that!
 
This week, I saw a documentary done by the French called Les sacrifiés de l'IA, which was presented by a Canadian show Enquête. If you understand French I recommend it. Very eye-opening. I found a similar documentary in English called The Human Cost of AI: Data workers in the Global South. There is also an interview with Milagros Miceli (appearing in both documentaries) on Youtube: I also found a powerpoint presentation by the economist Uma Rani (appearing in the French documentary), AI...
