Documentation

Installation

This package requires patching AMCL (obligatory) and Stage (optional). The AMCL patch is necessary to publish a Weighted Point Cloud needed for the calculation.

Get the necessary packages:

rosws merge https://kforge.ros.org/collvoid/collvoid/raw-file/tip/collvoid.rosinstall
rosws update

patch AMCL:

roscd collvoid
mv amcl.patch ../navigation
roscd navigation
patch -p1 < amcl.patch

and Stage:

roscd collvoid
mv stage.patch ../stage
roscd stage
patch -p0 < stage.patch

Compile the necessary packages:

rosmake collvoid navigation stage

Create a test environment and run:

roscd collvoid_stage
./scripts/create.py -n 4 -s 1.7
roslaunch collvoid_stage sim_created.launch

The create script has the following parameters:

-n <num of robots>
-s <radius of circle>
-l (use ground truth instead of AMCL)
-o (use omnidirectional robots instead of differential drive)

You can control the simulation in the controller window. Send initial guess will send an initial guess to every robot (necessary if AMCL is used). Start will start the simulation. Reset will reset stage to the initial configuration.
