Disable upper body control when walking about robotis-op3 HOT 11 CLOSED

In order to play the motion and make OP3 walk, each joint has to be set with specific modules that control joints.
There are two methods to set modules on joints;

• The first method configures predefined set of joints with a specific module. You can use either the topic or the service for this method as shown below.
  • topic name : /robotis/enable_ctrl_module
  • service name : /set_present_ctrl_modules
• The second method sets each joint with specific modules separately. You can also use the topic or the service for this method.
  • topic name : /robotis/set_joint_ctrl_modules
  • service name : /robotis/set_present_joint_ctrl_modules

You might want to use the second method to control each joint as you wish.
Please refer to the below link to see the example of how to set different modules on the head and the body.

Hi,
Sorry for the delay. I've managed to test the method suggested above, and I can confirm that it works.

However, there seems to be a weird behavior for the ankles. Whenever I use /robotis/set_joint_ctrl_modules to set them into walking module, one of them moves into a weird position, somehow.

This video should explain the problem better:
https://youtu.be/EStDLiBS500

This is the command that I ran:
$ rostopic pub /robotis/set_joint_ctrl_modules robotis_controller_msgs/JointCtrldule '{joint_name: [l_ank_pitch, r_ank_pitch], module_name: [walking_module, walking_module]}'

Hope you could check whether this is a bug in the code, or its due to some of my settings. And hopefully solve the problem too.

The same ankle behaviour is observed when setting the module via service /robotis/set_present_joint_ctrl_modules.

Hi @ROBOTIS-Kayman,
Any update on this? Did you manage to replicate?

@arixrobotics
I'm sorry I'm late. I was on business trip for 2 weeks.
I did not start this problem. Another job is scheduled for now.
I think I can start this issue after that.

When I reproduce this condition, I will let you know.

As soon as you can please. Our client is waiting too :)

I'm going to close this until you update the issue with more information. If you do so I'll reopen the issue.

Hi @arixrobotics
I'm sorry I'm late. We found the cause of this error. It's a initialize problem.
Pull the master branch and merge with it. then this issue will be gone.

Cool!
Unfortunately I don't have access to the robot anymore. I'll ask my client to test it out, in the mean time, let's consider this closed.
Thank you for your help!
