for the message's type of the 'open_base/command'

[hulingxiang666]

Hello,thanks for your work.
I'm a student who just started learning ROS.
I want to control the robot by the topic 'open_base/command',but I found that message type ‘open_base/Movement’ with topic '/open_base/command' does not exist.
And the colour of the whole robot is white.
My version is Melodic.
Looking forward to your reply, thank you very much!

Hi there. Thanks for taking an interest in my work!

In order to fully answer your question, I'm going to need to build a new ROS environment, as I've got a new computer and haven't done that yet.

Until then, could you please tell me exactly how you're trying to issue commands to /open_base/command? A full terminal dump would be even better, to see if there's wrong with the setup.

I also would like to ask for forgiveness in advance because I've been running really low on free time as of lately and it might take a while to be able to reply again.

ROS's learning curve may be a little steep but don't give up, it's rewarding.

Thank you very much. You are such a warm-hearted man.
The full terminal dump is given in the 'terminal dump.txt'.

And I'm used to using ROS Toolbox to connect MATLAB with ROS,because I use MATLAB to obtain the optimal trajectory.
Looking forward to your reply!
