[Question]: Gripper won't open to the max limit #27

Closed aaravrav142 closed 1 year ago

Question

Hello, I am using the Locobot wx250s model on ROS noetic. When using the joystick control for operating the arm using the command roslaunch interbotix_xslocobot_joy xslocobot_joy.launch robot_model:=locobot_wx250s controller:=ps4 The gripper does not open completely. the closing part is not a problem. I though it could be because of the slider getting stuck between the rails and added some lubricant but the problem persists.

Can you suggest how can I fix this problem or other ways I should check if the gripper is operating fine.

Thanks

Robot Model

locobot_wx250s

Operating System

Ubuntu 20.04

Could you provide more information about the issue including the following:

  1. A picture/video of the behavior you're experiencing
  2. What you expect the behavior to be
  3. What you have tried to solve the issue (if anything other than adding the lubricant)
  4. A rostopic echo of the LoCoBot's joint states at its "max"
  5. If you have changed anything like the default configurations, launch files, etc.

Closing due to lack of activity.

Hi, Sorry for the late reply. I was travelling during the new year. Please check the video below to understand the problem. Basically, the gripper closes properly but needs some assistance when opening. I do not have access to the bot right now. Once I return to the office, I can send the values of the joint state. Other than launching the sample joystick launch on the locobot, I did not change or do anything. Thanks, https://photos.google.com/photo/AF1QipNL7wR2mzRXK8cr3NU7CZQUfnlEkY_AF2305e03
