p3dx_2dnav_simulator

This repository simulate a p3dx mobile robot in willowgarage.world of Gazebo with Map Server, AMCL, Move Base, RVIZ and a PID controller. The PID controller is for tracking the reference linear velocity provided by local planner of move_base.

Install

$ cd <catkin_ws>/src
$ git clone https://github.com/chungying/p3dx_2dnav_simulator.git
$ cd ..
$ catkin_make

Execution without PID contorller

• Running the original settings for a p3dx robot
  • p3dx in Willog Garage world at (0, 0, 0) pose

$ roslaunch p3dx_2dnav p3dx_2dnav.launch

• Assignin robot to be at different initial pose
  • p3dx at (-4, -4, 3.14159) pose

$ roslaunch p3dx_2dnav p3dx_2dnav.launch ip_x:=-4 ip_y:=-4 ip_a:=3.14159

Execution with PID contorller

• Running the simulation with PID controller. Default pose is (0, 0, 0). Default PID gains is (0.8, 0.001, 0.01)

$ roslaunch p3dx_lin_vel_pid p3dx_2dnav_pid.launch ip_x:=-4 ip_y:=-4 ip_a:=3.14159 Kp:=1 Ki:=0 Kd:=0

Publish Goals via RVIZ and Monitor via rqt_plot

• Using 2D Nav Gaol to set up Goal pose

• Monitoring the reference velocity (blue line) and the velocity of p3dx (red line). This rqt_plot is set in rat_plot.launch and called by both p3dx_2dnav.launch and p3dx_2dnav_pid.launch.

Test Environment

• Ubuntu 14.04
• ROS Indigo

Stuff used to make this:

• ua_ros_p3dx for p3dx_gazebo and p3dx_description
• ros-planning/navigation for p3dx_2dnav
• messege_filters, nav_msgs, and geometry_msgs for p3dx_lin_vel_pid
• gmapping and map_server for building willowgarage
