INSTITUTE: Nanyang Technological University, Singapore

MEMBERS: Tanmay Vilas Samak, Chinmay Vilas Samak and Chern Peng Lee

ADVISOR: Dr. Ming Xie

1. Robot Operating System (ROS) - Tested with ROS Noetic Ninjemys on Ubuntu 20.04.4 LTS (Focal Fossa).
2. Virtual RobotX (VRX) Simulation Environment - Included as vrx directory with this SINGABOAT-VRX repository.
3. Python3 Dependencies - Listed in requirements.txt file of singaboat_vrx ROS package. These can be simply installed using the following command:

   $ pip3 install -r requirements.txt

1. Clone this SINGABOAT-VRX repository:

   $ git clone https://github.com/Tinker-Twins/SINGABOAT-VRX.git

2. Make a directory VRX_Workspace to act as your catkin workspace for VRX Competition.

   $ mkdir -p VRX_Workspace/src/

3. Move the SINGABOAT-VRX repository to the source space (src) of your VRX_Workspace.

   $ mv ~/SINGABOAT-VRX ~/VRX_Workspace/src/

4. Build the packages within your VRX_Workspace.

   $ cd ~/VRX_Workspace
   $ catkin_make

5. Source the setup.bash file of your VRX_Workspace.

   $ echo "source /home/$USER/VRX_Workspace/devel/setup.bash" >> ~/.bashrc
   $ source ~/.bashrc

1. Launch any VRX task simulation instance.

$ roslaunch vrx_gazebo <TASK_NAME>.launch urdf:=$(rospack find singaboat_vrx)/urdf/singaboat.urdf

$ roslaunch vrx_gazebo station_keeping.launch urdf:=$(rospack find singaboat_vrx)/urdf/singaboat.urdf
$ roslaunch vrx_gazebo wayfinding.launch urdf:=$(rospack find singaboat_vrx)/urdf/singaboat.urdf
$ roslaunch vrx_gazebo perception_task.launch urdf:=$(rospack find singaboat_vrx)/urdf/singaboat.urdf
$ roslaunch vrx_gazebo wildlife.launch urdf:=$(rospack find singaboat_vrx)/urdf/singaboat.urdf
$ roslaunch vrx_gazebo gymkhana.launch urdf:=$(rospack find singaboat_vrx)/urdf/singaboat.urdf
$ roslaunch vrx_gazebo scan_dock_deliver.launch urdf:=$(rospack find singaboat_vrx)/urdf/singaboat.urdf

2. Launch singaboat_task_manager to automatically identify the VRX task and execute the corresponding SINGABOAT-VRX solution algorithm.

$ roslaunch singaboat_vrx singaboat_vrx.launch

The docker container image(s) containing all the source code as well as dependencies is available on Docker Hub.

Demonstration videos are available on YouTube.
