Ohara124c41/RSEND-Home_Service_Robot

Combined AI paradigms to build a home service robot that can map, localize, and navigate to perform household tasks, moving from one room to another autonomously.

RoboND-HomeServiceRobot-Project

The goal of this project is to program a robot than can autonomously map an environment and navigate to pick up and drop off virtual objects. List of the steps in this project :

• Write a Shell Script
• Design your environment with Gazebo Building Editor
• Test SLAM
• Wall Follower to map the environment
• Test Navigation
• Reach Multiple Goals
• Model Virtual Objects
• Put it all together

Project setup

Update your system: sudo apt-get update

Install the ROS navigation stack: sudo apt-get install ros-kinetic-navigation

Create catkin workspace, if you haven't already.For this project catkin_ws is used, if your workspace name is different, change the commands accordingly.

$ mkdir -p ~/catkin_ws/src
$ cd ~/catkin_ws/src
$ catkin_init_workspace
$ cd ~/catkin_ws
$ catkin_make

Clone the following repositories to catkin_ws/src:

$ cd ~/catkin_ws/src
$ git clone https://github.com/ros-perception/slam_gmapping.git
$ git clone https://github.com/turtlebot/turtlebot.git
$ git clone https://github.com/turtlebot/turtlebot_interactions.git
$ git clone https://github.com/turtlebot/turtlebot_simulator.git

Install package dependencies with rosdep install [package-name]

Copy content of this repository to catkin_ws/src

Catkin workspace should look something like this:

Source and build the project:

$ cd ~/catkin_ws
$ source devel/setup.bash
$ catkin_make

To run home service robot navigate to ShellScripts directory and run ./home_service.sh

After running you will see (int Rviz) robot picking up a virtual object from the pickup zone and dropping it off at the drop off zone.
