    Change ROS Master on Sawyer

    I would like to have my ROS Master running on a different system. Is it possible to set another system as the ROS Master instead of Sawyer?

    Vision Pick

    Hello, Your object is recognized (highlighted in green) but look that not all. Two edges are outside of green rectangle. Try to broaden object field, because all edges should be inside of field, green rectangle (during snapshot) cannot cut of any object edge. Also i have few question : 1. If you create surface in snapshot editor you put Landmark on the table or on your object ? 2. Does your object lie on the hard or soft base ? Cheers Lukas

    Vision Pick

    Hey, thanks again for your response. Unfortunately it's still not working. We pressed "Gehe zu" and set the similarity to 20% and the angles to -180 and 180, but still couldn't press "Verschieben". We tried over and over again, but without success. The problem might be that it says on the screen "Armcamera" instead of "Armcamera is proofing" (or similar). The camera does find the object though and there is the green rectangle around it. Best, Katharina and Max

    Cannot Control Sawyer using SDK

    For all future visitors, I have found the problem: It seems our company workstation have some kind of firewall or other networking settings that block the avahi mDNS service. To confirm my finding I installed vanilla ubuntu on an old workstation we had lying around. With that workstation it worked like a charm. Cheers

    Vision Pick

    Hello Katharina , This button is available only when your object was recognized by vision system. First press the button GEHE ZU - the robot goes to the position where you were doing the snapshot. If it does not help so.. I suppose that you have to change settings e.g. 1. similarity threshold 2. start angle 3. end angle or try to create snapshot and vision locate from the beginning and remember that you can not move your object during programming. Cheers Lukasz

    Vision Pick

    Hi Lukasz, Thanks a lot for the nice description! But we have a problem as you can see in the attached picture. We are not able to choose "relocate" if we test the snapshot. Do you have any idea? Thanks in advance! Katharina & Max
  11. Hi everyone! I'm trying to do motion planning pipeline with moveIt in my Sawyer but there are only tutorials in c++ by MoveIt!, when i run this tutorial i have a error with systaxis (but i'm sure that it's okay). do anyone some code or tutorial about it in python? or do anyone know if i need to do anything to copile code in c++? can anyone help me? thanks a lot!

    Vision Pick

    Hello Katharina , If you know how to create a locator and how to do pick and place it will be simple for you to create Vision Pick. Below you can find a short instruction on how to create it : 1. Create Locator in Snapshot gallery. (Just in case instruction here)- DO NOT MOVE YOUR OBJECT 2. Close all windows/nodes in Intera. 3. Open Vision Locate node and choose your object. 4. Click on the button TEST (in Vision locator node - at the top left corner) 5. If your object is found, it should be highlighted in green and then click RELOCATE. (there should be confirmation - RELOCATED) - DO NOT MOVE YOUR OBJECT 6. Create Pick & Place (most important are : Pick should be children of the Vision Locator node - toggle on the vision locator node, click on this and it should be highlighted in orange, then create Pick & Place) Remember, your object has to be in one place all time after you execute (Point 5 - RELOCATE). Good luck. Please let me know if it is helpful for you. Cheers Lukasz

    Vision Pick

    Hey guys, I'm need to create a Vision Pick but don't know how, unfortunately I don't have access to the training portal. It's supposed to be a very simple pick and place of an static object that's somewhere on a table. I know how to create a locator in the snapshot galery and also how to pick and place. What's missing is the connection inbetween. How do I tell Sawyer to pick where the object is located? Best regards and thank you, Katharina
  17. Do you have any code you could possibly share? Especially how you go around calculating velocity and acceleration. I've avoided using the joint trajectory method as I don't have the time to implement it, I've managed so far with just the ik and set_joint_positions and the Motion Waypoint system.

    Locked up on software update

    Hi Lukas, Thankyou for your help. Followed the instructions, on rebooting after the update the robot is not powering up properly, locked up on attached view of the screen ,none of the controls work and it has not referenced the joins. I have emailed the support as recommended on the instruction sheet. Cheers Garry

    Model of the Force Sensor

    Hi, It is a special combination with the "springs" so it is a custom measure system.

    MoveIt no work with my sawyer

    Hi everyone! i am trying to move my robot with MoveIt, but i can´t do. if i try to move my robot with intera_examples, it work perfect. But i would like to move by MoveIt because this tool can help you to do trayectories robot easier. i have followed the tutorial, but when i plan the trayectory and after that execute i have some warnings : -1 warning : No trasform avaible between frame 'reference/right_gripper_r_finger_tip' and planning frame '/base' (could not find a connection between 'base' and 'reference/right_gripper_r_finger' because they are not part of the same tree. Tf has two or more unconnected trees) /// I think this warning no is a problem -2 warning: Interactive marker 'EE_goal_right_gripper_tip' contains unnormalized quaternios -3 warning: Didn´t received robot state (joint angles) with recent timestamp within 1 seconds. check clok synchronization if your are running ROS across multiple machines! failed to fetch current robot states failed to validate trajectory_ couldn`t receive full current joint state within 1s // i think that it is teh problem, but i can fix it, anyone can help me??? or someone have the same problem or can anyone say me how can work with moveit and sawyer??

    Cannot Control Sawyer using SDK

    I think you have a problem of communicate between Robot and your computer. the first time i try it like you, after that i can get the date like angles, force etc, but when i try to move my robot, it not work. So, i had to correct my communicate and after that it work. (if you can do ping <hostname.local> and your computer, it will have to work)

    What is the model of the force sensor in Sawyer? Or is it custom made?
