@AndyZe I actually have the gazebo simulation ready and I can see it work

@gvdhoorn right now my focus is just the simulation of the bot. That's why I wanted to be sure. I shall look up gazebo_r

@gvdhoorn correct me if I am wrong, for applying `jog_arm, I need the drivers of the arm I am controlling? If yes, are t

Hey,

I was going through the Moveit tutorials here: Moveit Commander Scripting and when I tried launching rosrun moveit_commander moveit_commander_cmdline.py, I am getting the following error:

kashyap@kashyap-Lenovo-ideapad-320-15IKB:~$ rosrun moveit_commander moveit_commander_cmdline.py

Could anyone guide me as to what this error means? Thanks

Thanks, the fix worked

Oh damn. Yes, you're right. Thanks for the help. I will apply asyncExecute too and try the same. Thanks again.

Hey,

I want to implement button debouncing for my xbox controller and I couldn't find anything much helpful till now. All the info that is available on google is related to microcontrollers. Is there an option or a way button debouncing can be implemented in a ros python code?

Thanks in advance

Edit:

@PeteBlackerThe3rd In the pic you can see that the joint changed once, when I gave the input through the controller, but instead of stopping at the first 'Plan complete', the loop ran for 7 more times, which causes a bit of delay in processing the second instruction given through the controller. Could you maybe point out my mistake or maybe guide me through the right process so that I can detect my mistake?

Edit-2 Code screenshot: I know it's not suggested to take a screen shot of the code and post it here, but I just wanted to make sure that the indentations I am having in my code are clear, since indentations are a not always correct here

This is my code
