Drone control with robonomics

Description

Drone starts moving after transcation and store file with the coordinates in IPFS.
The control script is based on the GAAS demo script

Environment Setup

sudo apt-get install ros-melodic-mavros ros-melodic-mavros-extras
wget https://raw.githubusercontent.com/mavlink/mavros/master/mavros/scripts/install_geographiclib_datasets.sh
sudo ./install_geographiclib_datasets.sh
cd ~/catkin_ws/src
git clone https://github.com/PX4/Firmware.git
cd Firmware
make posix_sitl_default gazebo
cd ~/catkin_ws/src

Modifying your .bashrc file, adding the following lines to the bottom:

source ~/catkin_ws/devel/setup.bash
source ~/catkin_ws/src/Firmware/Tools/setup_gazebo.bash ~/catkin_ws/src/Firmware/ ~/catkin_ws/src/Firmware/build posix_sitl_default
export GAZEBO_MODEL_PATH=:~/catkin_ws/src/simulator/models
export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:~/catkin_ws/src/Firmware

export GAZEBO_MODEL_PATH=:~/catkin_ws/src/simulator/models:~/catkin_ws/src/GAAS/simulator/models

Control Package Installation

cd catkin_ws/src
https://github.com/tubleronchik/robonomics_drone_sim.git
cd ..
catkin build

Robonomics Network

To create a local robonomics network go to the folder with the robonomic binary file and run:
./robonomics --dev --rpc-cors all

Add robonomic's path to config.py

IPFS

Go to the Robonomics Portal and switch to local node. localNode

Go to Accounts and create DRONE and EMPLOYER accounts. Save the account names and keys and path to robonomics to ~/catkin_ws/src/drone_sim/src/config.py. Transfer some money into the accounts.

accounts

Running Simulation

Run IPFS daemon

cd go-ipfs
ipfs daemon

In another terminal launch the simulation:

roslaunch px4 mavros_posix_sitl.launch
cd ~/catkin_ws/src/drone_sim/src
python3 takeoff.py

Waiting till "Waiting for payment"

launch

To send a transaction run in another window: echo "ON" | ./robonomics io write launch -r <drone_addres> -s <employer_key> - where <drone_address> and <employer_key> should be replaced with the strings from config.py accordingly.

After data was pushed to IPFS, go to the Chain State in Robonomics Portal. Select datalog in query and add DRONE datalog using + button.

datalog

You can find drone's telemetry running https://gateway.ipfs.io/ipfs/<hash> inserting the hash from above.

output

It's important to remove db derictory before next launches using
rm -rf ~/.local/share/robonomics/chains/dev/db
