Robot Operating System (ROS) +robot simulator (V-REP)

  • Build 2D grid map with laserscan data avia rviz
  • Control the mobile robot in the vrep simulation environment with keyboard
  • Image Recognition and localization
  • Visual Servoing (follow the yellow ball)
  • roslaunch ros nodes

SETUP

ROS install and catkin

  1. Install catkin: http://wiki.ros.org/catkin
  2. Install ROS: http://wiki.ros.org/ROS/Installation

$ echo "source /opt/ros/kinetic/setup.bash" >> ~/.bashrc
$ source ~/.bashrc
$ mkdir -p ~/catkin_ws/src
$ cd ~/catkin_ws/
$ catkin_make
$ echo "source ~/catkin_ws/devel/setup.bash" >> ~/.bashrc
$ source ~/.bashrc
  1. Install the needed ros packages
#install hector slam
$ sudo apt install ros kinetic hector slam
#install key teleop
$ sudo apt install ros kinetic key teleop

Install V-REP

$ tar -zvxf ~/V-REP_PRO_EDU_V3_4_0_Linux.tar.gz
$ mkdir ~/V-REP
$ mv ~/V-REP_PRO_EDU_V3_4_0_Linux ~/V-REP

Load RosInterface and Some Packages

  • Copy everything in this repo except README.md env.ttt hector.launch picture/ to ~/catkin_ws/src/
$ cd ~/catkin_ws/
$ catkin_make
$ source ~/.bashrc
  • Copy libv_repExtRosInterface.so
$ cd catkin_ws/devel/lib
$ cp libv_repExtRosInterface.so  ~/V-REP

RUN
