Try to run ros natively in my Ubuntu 16.04
- Install ros (follow ROS website instruction)
- Try to catkin_make from ros folder, got cmake errors: Could not find a package configuration file provided by "dbw_mkz_msgs"
- Follow instruction in the project README to install Dataspeed DBW (since I am not using Udacity VM, which already included the package)
- catkin_make succeeds
- roslaunch fails because _tf2 module not found. _tf2 has been installed but somehow roslaunch cannot see if
- Try using python 2.7 to see if the problem is because of the use of python 3
- Create conda env ros with python2.7 and catkin_make under this env
- pip install -r requirement.txt
- catkin_male complains about module em. Do pip install empy
- catkin_make succeeds. roslaunch complains about rospkg
- pip install rospkg
- roslaunch complains about catkin_pkg.packages
- pip install catkin-pkg
- no more complains
- run Udacity simulator
- succesful open the simulator & see response fron ros
Try to get the car to move
- create branch get-car-moving
- uncomment code that creates and calls the controller
- set throttle = 1
- logwarn confirms that the function is called, but the car does not move
- In the simulator, uncheck manual --> the car moves
- Implement simple way point updater
- Use YawController for DBW controller
- The car now follows the track
