Anyone using the IIWA |

Does anyone have experience using the IIWA in a production environment? If so, how does it compare to the UR? I have not seen very many videos on YouTube of the robot working in an actual production environment. Most of the videos appear to be demo type videos of what it might be capable of doing. Also, how is the pricing on these? Kuka has been slow to respond to requests even though they are supposed to call me back later in the week...
@matthewd92, what functionalities are you looking for?

Our UR10 is the cheapest we have. And with that many factors come in hand. Limited options to communicate, No solenoid, not rigidity in arm, vibration prone, etc.
When I connect the robotiq gripper and compare in both robots, UR10 seems like it's vibrating a bit. In the case of the study of the surface, both robots compared, and the variations were quite astounding.
Cheap may come with a hidden price tag.
Also, not saying UR10 is the worst robot, but production side will kill us if we send something that sometimes work and other 9 times don't.
When you connected the gripper to the UR10 did you adjust the TCP payload and CG settings? If not, you will get some vibration as the robot tries to counteract gravity. I actually use a gram scale to weigh all of my end effectors including the bolts to get as accurate as possible to get the best performance possible.
We have had some UR10's and UR5's running in production, 10 hours a day for a year and half without any real issues from the robots. We currently have a UR5 that runs on average 15-18 hours per day, 5-6 days a week and the robot has been free from mechanical issues (had a bug in the software that would cause an issue but they found it and fixed it and haven't seen that issue since) and it runs around 90% max speed and 80% max acceleration through its entire operation of running a punch press. Knock on wood now that I am bragging on it.....
@matthewd92 I can also express the same frustration about KUKA. Many times I have tried to communicate and even to take training, but it is extremely slow. In terms of price, for our case the price difference was about 3 times higher compared to UR.
Hahaha that is something to truly brag about. I am actually happy to hear that you guys use URs in this fashion as we can't have access to manufacturing environments or applications of the same sort. Truly informative.
That is good to know as we try to explore different software to program robots. Maybe out of the topic, but has anyone utilized ROS-I for these kind of applications?
In the interests of fairness , please take a look at the attached video link, real application, real Human Robot Collaboration, no guarding.
Could you share a few details regarding the application? How does the robot detect the contact with the human during the assembly task? Is this contact detected by the iiwa and how would you configure this function in a program?
Are there any external safety sensors used in this application?
Could you share some details regarding the tooling that is mounted on the iiwa's media flange? Is this electrical or pneumatic?
