keyboard velocity operation

[glakshay]

Hi, I am trying to use key_board_velocity.launch to control the vehicle but the this doesn't move the vehicle and the keys pressed do not immediately correspond to the terminal window (that is slow to take in input commands). I am using the following commands in order:

1. roslaunch uuv_gazebo_worlds empty_underwater_world.launch
2. roslaunch uuv_descriptions upload_rexrov.launch mode:=default x:=0 y:=0 z:=-20 namespace:=rexrov
3. I tried two variations for the keyboard operation but both are not working roslaunch uuv_control_cascaded_pid key_board_velocity.launch model_name:=rexrov or roslaunch uuv_control_cascaded_pid key_board_velocity.launch uuv_name:=rexrov model_name:=rexrov I use variations of say q, a, 1/2 but nothing seems to work. Also, on pressing ctrl+c, I get the error: _

[rexrov/keyboard_uuv_velocity_teleop-4] process has died [pid 61583, exit code 255, cmd /home/lak/catkin_ws/src/uuv_simulator/uuv_teleop/scripts/vehicle_keyboard_teleop.py output:=/rexrov/cmd_vel __name:=keyboard_uuv_velocity_teleop __log:=/home/lak/.ros/log/3087991e-2dcb-11eb-82db-000c29a26e1a/rexrov-keyboard_uuv_velocity_teleop-4.log]. log file: /home/lak/.ros/log/3087991e-2dcb-11eb-82db-000c29a26e1a/rexrov-keyboard_uuv_velocity_teleop-4*.log

Thanks for the help!

I tried to reproduce the problem you encountered and it did not work. I found that there was an error complaining that the node with the type vehicle_keyboard_teleop.py could not be found. It seems like there was a line missing in the /uuv_teleop/CMakeList.txt. You can try to add a line scripts/vehicle_keyboard_teleop.py into the catkin_install_python part and do catkin build then see if it works.

Yeah, I solved the problem on my computer by adding the line, but I am not sure if it will fix everything for you.
