Two wheel Simple Robot SLAM and Gmapping

Robot view

This project demonstrates how to implement SLAM (Simultaneous Localization and Mapping) using the Gmapping algorithm on a two-wheel robot with two caster wheels.

Table of Contents

Overview

This repository contains the necessary code and instructions to build and run a two-wheel robot equipped, and Sick 2D LiDAR with SLAM capabilities using the Gmapping algorithm. The robot uses two main wheels for movement and two caster wheels for balance.

Features

  • Implementation of SLAM using the Gmapping algorithm.
  • mapping capabilities.
  • Real-time visualization using RViz.

Requirements

  • ROS (Robot Operating System) Noetic
  • Catkin workspace
  • Ubuntu 20.04

Installation

Step 1: Clone the Repository

mkdir -p catkin_ws/src
cd catkin_ws/src
git clone https://github.com/SAJIB3489/sick_robot.git
cd ~/catkin_ws
rosdep install --from-paths src --ignore-src -r -y
source /opt/ros/noetic/setup.bash
source ~/catkin_ws/devel/setup.bash
catkin_make

Step 2: Launch

Launch gazebo simulation

roslaunch sick_robot_description gazebo.launch

Launch RViz Open a new Terminal.

roslaunch sick_robot_description display.launch

Start Gmapping Open a new Terminal.

roslaunch sick_robot_description mapping.launch

Drive the robot using keyboard Open a new Terminal.

rosrun teleop_twist_keyboard teleop_twist_keyboard.py

If you do not have the package install it using sudo apt-get install ros-$ROS_DISTRO-teleop-twist-keyboard

simulation

To save the map

rosrun map_server map_saver -f robot_map
