I am following this tutorial for my dynamixel application but facing the error for most of the packages created.

NODES / torque_control (dynamixel_workbench_controllers/torque_control)


ERROR: cannot launch node of type [dynamixel_workbench_controllers/torque_control]: can't locate node [torque_control] in package [dynamixel_workbench_controllers] No processes to monitor shutting down processing monitor... ... shutting down processing monitor complete

Please help! Thanks.

ok, so you want to run it from source. Did you build it?

since its on my RPi3 (Raspbian buster platform), and i created this package and launch file while issuing catkin_make , it shows error of not building non-homogeneous packages..... Is that the reason or something else? I had spent lot of time to fix this but failed. plz help. Thanks.

yes. this is the problem then. If you can not build the software, you can not launch it. Maybe you can open a new question to solve your problems with the build
