Hello, here is RIKUTO. I'm facing a problem right now. I'm trying to manipulate xarm6 on matlab. but the following error occured when generate ROS message using " rosgenmsg " function. "The index exceeds the number of array elements. Index must not exceed 1." error The package used to generate the message is an official package cloned from this site. I tried the command " clear rosgenmsg " and rosdep, but the error not solved. Do you have any solution ? I'm in so much trouble. On another robot arm's ros message, generation ros message is succeeded. Does anyone have the same case? Kindly await your help !! thank you.

Hi @OsitaRikuto, have you made any modifications from our original code? We have no experience with MATLAB ROS supporting functions, but I may infer from the error message and it seems there is a line in certain srv file which some (value) part is missing? Also, have you tried the package can be successfully built in ROS catkin method?

Hi @penglongxiang Thank you reply, I have no modifications from this official pakcage. As a next measure, I would like to copy only the msg and srv directories to other new folders and verify whether this is the case with those folders. If you don't mind, I would appreciate it if you could let me know if there have been any such cases in the past. Thanks for your support, I appreciate it. Thanks.
