  • Palletizing Using the Wrist Camera Program Template

    Hi Pros, 

    Here's the program template of the week! It allows you to manage objects in stacked trays using the Wrist Camera. It uses an advanced function that enables the use of the same snapshot position at different heights. Thus, only one object teaching and snapshot position are required to pick objects from trays at different heights.

    Get the program template here and here's a glimpse of the program in action:



    If you haven't caught the previous templates, you can find them all here

  • Link the Universal Robots' e-stop to the Gripper's power supply

    Hi Pros,

    I wanted to share with you how to configure Robotiq's 2-Finger Gripper on a UR so that it loses its power when the e-stop button is pressed. Here is how I do it: 
    • Instead of connecting the 2-Finger Gripper's red wire to a 24V pin, I connect it to a configurable output. In this example, I connected it to configurable output 0 (CO0). 
    • I connect the rest of the wires as described in the instruction manual

    • On the UR teach pendant, open a Robot program and go in the Installation tab. Click on Safety and enter the password, if required. 
    • From the Safety I/O tab, change the function assignment of the configurable output you connected the red wire to. Change it to System Emergency Stopped. In the example, I changed CO0 and CO1. 

    Performing this will cut power to the gripper when the robot's e-stop button is pressed. When it is restored, the gripper will get power back again. Remember that you will need to activate the gripper since it lost power. 

    If you would like to know more on how to integrate a gripper in a collaborative robot cell, make sure you check out this eBook
  • How to Program Using the Wrist Camera

    Hi Pros,

    Here is a quick video showing you how to program a pick & place using the Wrist Camera. Notice we have used a MoveL with the appropriate feature in order to perform robot motion relative to the detected object.

  • Re: Wrist camera as coupling and adapter plate on ROS

    @edavio you will be able to use the package. The only thing you need to make sure is that you identify the correct USB device. When you launch the ROS package, it will ask you what USB device to communicate with. Make sure you select the proper one. I you are not sure, you can look at the list of USB devices that are connected. 

    Feel free to post below if you have further questions. 
  • Re: Getting Robotiq 2F85 gripper position in program using URCAP

    @Sebastien ;@lawrence manual link was missing, here it is. Sebastien, you are right you can only read the values that were set, there is no direct force sensing on the Gripper. However, if you want to have an estimate of the values you will get, check the tables in section 4.5 of the manual.
