ROBOT LIBRARY ISSUE: Fanuc R2000iB/165F Model Innacurate
#1
Greetings,

I'm working on a reach study and path simulation with 2 Fanuc R2000iB/165F robots and have noticed that the RoboDK Library model is not accurate.

What's the easiest way to correct this without having to model the robot ourselves?

Are we looking at waiting for a Library update to address this?

Specifically, the counterbalance on the back of J2 is not the right size (see attached visual comparison)
   

In our Solidworks model of the cell, we have no collision issues, but in RoboDK we have collisions due to the larger counterbalance.  We purchased RoboDK so that we wouldn't have to rely on Solidworks for these types of reach studies & path simulations / collision checks, but it's leaving some doubts now.

We've compared the 3D CAD model from Fanuc vs. the RoboDK model and they're definitely not the same for this particular robot model.

It's also possible that the other variations of the R2000i robot arm are not accurate as well, I have not done a detailed check on those, but the RoboDK models look similar to the 165F and don't seem to match pictures of the actual robot arms where the counterbalance is concerned, so I'm thinking they're suffering from the same inaccuracies.

Thanks,

Can you provide the correct STEP files of the Fanuc R2000iB 165F robot?
We can update it.

Thanks Albert.

Here's the STEP file we received from Fanuc.

I attached the updated version of this robot. We also updated it in our library.

Thanks Albert.

Here's the STEP file we received from Fanuc.

I provided the R2000iB model, but just found out that our customer has switched to the R2000iC.

We're still seeing the same issue with the model comparison from Actual to RoboDK.

Here's the R2000iC STEP file we received from Fanuc.

Thanks Albert.  I've downloaded the updated version of the R2000iB/165F and it looks better.

Are you able to update the C version of this robot as well (R2000iC/165F) using the STEP file provided in my previous update?  Our customer has changed to the R2000iC, so we need to provide simulations for that model now and it suffers from the same issues that we saw with the R2000iB/165F.

Thank you
