I have been using Roboguide for the last couple weeks and have managed to figure out most of everything i needed. Big problem i am having is when i am simulating some programs (still teaching points) it will go through the motions and pick and place the parts i need but i cant figure out how to reset the part location. Example is it will pick from my pick location then place in the gage i need but then i need the part to not be in the gage anymore to start from fresh. Anyone know how to "reset" where the part will no longer be in fixtures ? Thanks in advanced

Roboguide has some very helpful tutorials that walk the user through the simulated creation and destroy of parts. I believe you will find the tutorials if you search "simple workcell" in the help section of Roboguide. You will be tweaking the create and destroy delays for your parts to make them appear and disappear. Hope this helps.

Hi!
If I remember correctly is in the "simulation" tab at the part properties you define how the part behaves during simulation -
I figured out my last problem with the parts but came across another. I am loading parts from a gage into a tray which will hold roughly 110 parts. I have two parts i created which will be placed into the tray from the gage, my problem is that when i place Part1/Part2 into the Tray i want it to remain there until the Tray is full. Does anybody know how to do this without creating 110 part locations within the Tray fixture?
-
Have you used the "add" button to add parts to the fixture? This makes it pretty easy. I think you'd be stuck setting up delays for every single part- tedious.
What is your purpose for making a simulation? I sometimes use it to demonstrate new concepts to customers. I think the simulation stuff is pretty slick but doesn't have much value outside of being a very powerful sales tool.
-
That is exactly what it is, a a sales tool. Some customers want it and pay for the simulation other don't. Okay so looks like i'm stuck creating 110 parts for the tray then.

You can set the delete time to 999 seconds on the tray, but I'm not sure of a "smart" way to put the parts on there and then delete them given a signal. Also, just to keep in mind, if you are using it just to analyze, you can just simulate placing the parts in the four corners or any extreme fixture locations to get a good idea.
Also, I find Roboguide very useful for any design engineer. Yes, the end result is usually selling your project to the management making the decisions or the customer, but it is very useful to get a rough idea of throughput (with robot cycle time), reach analysis, and concept work in general. When used right, it definitely cuts down on wasted time on the floor from programming, conflict, or reach issues!

That is true, we have just started using Roboguide so i suppose i am scratching the surface. We decided ultimately we would just show the robot motion going to each spot within the tray and not have the parts physically be there because creating 100 something different part locations would take to much time.
I have moved onto a new job and wondering if there is anyway to simulate a machine cycle time possibly through DI in the simulation. I cant find anywhere to do that. I want to service a machine give it a "Cycle start" (i know the cycle time of machine is 6.5 minutes) continue on through the cell but not be able to service that machine again until i get some sort of signal back saying "machine ready for service". I hoping this is possible to do otherwise the programming for the simulation to real world are going to be very different. Thanks again!! -
What are you thinking as far as "service"
The feeding of a blank or actual machine service? -
Use a timer. You can loop back and check the timer value to see if the "machine" is ready.

I will try a timer and see how that goes. When i say service i mean pick then place parts into/from the machine.

Ok.
If I understand correctly you will feed the robot a part. You will then press cycle start. The robot will preform some function. At that point. you would like a signal to tell you that you need to either feed it another part or remove the finished part and then feed it another part.If that is the case the way I do it is to have the robot wait for me.
When the robot finishes the cycle of the previous part, whatever it's end point is, dropping in a finished bin or placing on a finished jig, my next step is to return it to a "perch" or home spot.
It remains there until my operator does his job of loading another part. This part is "sensed" to verify, plus the operator will press a "cycle start", or "resume" button.
We typically use a rotating table for smaller stuff or separate feed and extract tables for the larger stuff.
I personally would be leery of timers because if some one makes changes to the cycle movements as far as speed or even length of paths it will effect over all cycle time.
There are a lot of safeties to prohibit operators from being in the envelope or the robot from moving while the operator is in the envelope.
If I have misunderstood your query then ignore this. Just mental gymnastics for me.
