CMakeLists.txt file modifications

Open lab_6_jointTrajectoryPlanner/CMakeLists.txt and add following lines to the bottom of the file.

catkin_install_python(PROGRAMS scripts/jplanner.py scripts/jclient.py
  DESTINATION ${CATKIN_PACKAGE_BIN_DESTINATION}
)

Build the code

Go to root of the workspace

cd ~/robotics/
catkin build

or

catkin_make

Simulate

First open a terminal window, move to robotics folder, source the devel/setup.bash and start the gazebo simulation

cd robotics
source devel/setup.bash
roslaunch open_manipulator_gazebo open_manipulator_gazebo.launch

Start the simulation by pressing the "play" button in the lower part of the screen.

Then open another terminal window, move to robotics folder, source the devel/setup.bash and start the gazebo controller

cd robotics
source devel/setup.bash
roslaunch open_manipulator_controller open_manipulator_controller.launch use_platform:=false

Then open another terminal window, move to robotics folder, source the devel/setup.bash and start the JointSpaceControllerServer

cd ~/robotics/
source devel/setup.bash
rosrun lab_6_jointTrajectoryPlanner jplanner.py

Then open another terminal window, move to robotics folder, source the devel/setup.bash and start the JointSpaceControllerClient

cd ~/robotics/
source devel/setup.bash
rosrun lab_6_jointTrajectoryPlanner jclient.py
