cmake error

[stevensu1838]

OS: 14.04 LTS ROS: indigo

I quickly ran through the commands on the github page. When I ran the launch file for the first time, I got the same frame warnings (ERROR: cannot launch node of type [ur5_inf3480/inf3480_move_robot]: can't locate node [inf3480_move_robot] in package [ur5_inf3480] ) but everything seems to work, so I wouldn't worry about that error. When I do run it (before adding the node),I can control the arm using the sliders (it's controlled by the python node that launches at the same time).

After adding the node, I tried running catkin_make again. The following is what happens next.

Hi,

It looks like I've accidentally left a typo in the code. If you comment out line 43 in inf3480_move_robot.cpp, it should compile and work. Then you can check the tutorial and uncomment some lines in 51-56 to execute some pre-programmed moves. Same for adding the collision objects in the robot environment.

Please note that this code is created as a teaching tool for students being introduced to ROS and not as a working product.

Hi Justas, Can you please elabrate on how to comment out line 43 std::vector ß; Coz it looks like it is not commented. Thank you so much for your help

Hi, @jmiseikis @stevensu1838 I am having a very similar problem. Before including the .cpp file everything was fine. Workspace complied and simulation worked perfectly. After adding .cpp file I got:

ERROR: cannot launch node of type [ur5_inf3480/inf3480_move_robot]: can't locate node [inf3480_move_robot] in package [ur5_inf3480]

The workspace will not compile either just as in the comment above. I have commented out line 43

std::vector collision_objects_list;

but there is no change. I'm desperately trying to work out how to control a ur5 using live, updatable script commands but every tutorial I find stops right at the important part. Although this github repo by @jmiseikis is the closest I have got so far. If only I could get this .cpp code to work!! @stevensu1838 Did you ever get a solution to your problem?

Kind regards, Dom.

p.s. I'm using ros kinetic on ubuntu 16.04.
