This repo contains the source for a really rough right wall follow algorithm.
The algorithm can be simulated by using this fork of the stdr_simulator branch: https://github.com/bgill92/stdr_simulator
-
To get started, clone this repo and the stdr_simulator repo to the src directory of a catkin workspace (make sure ROS is installed. I have used this with ROS Indigo and Kinetic)
-
Build the catkin workspace
-
Have two terminals open, navigate to the root directory of the catkin workspace and in the first terminal, run:
$ roslaunch stdr_launchers trin_bot_maze1_xacro.launch
and in the second terminal run:
$ rosrun right_wall_follow rwf_sonar
Hopefully everything works and happy simulating!
