RPZ planning

Demo

This is a quick-start section, which describes how to use the rpz_planner as a stand-alone package without installation of the entire exploration pipeline. If you would like to explore, how the trajectory optimization works using a prerecorded data (as a ROS bag-file), please, follow the instructions in docs/demo.md.

Prerequisites

Exploration with trajectory optimization

Start the simulator using the simgularity image cloudsim.simg:

cd ~/subt_virtual/scripts/
SUBT_USE_SINGULARITY=1 SUBT_ROBOT_TEAM=x1x2 ./run_sim worldName:=simple_cave_01

Run the ROS-bridge to the simulator:

cd ~/subt_virtual/scripts/
SUBT_USE_SINGULARITY=1 SUBT_ROBOT_TEAM=x1x2 ./run_bridge_all worldName:=simple_cave_01

Run exploration pipeline (naex) with local trajectory optimization:

roslaunch rpz_planning naex.launch follow_opt_path:=true
