Our effort for The MOBI Grand Challenge (mobihacks.devpost.com) in kind cooperation with Chorus Mobility (www.chorus.mobi) and Decentralized Technologies (www.dczd.tech)

1. Self driving car ask UTM for a permissioned path between point A and point B
2. UTM offers a path permissioned
3. Self driving car send an acceptance message
4. Robonomics network provider create a permission in form of smart contract
5. When contract achieve Ethereum blockchain, permission became immutable

• Vehicle Alice (Agrees to be Slower/Accept Payments and give Rights of Way) This car's passenger made a preference selection to pay for a ride less money but arrive later than average ETA, within certain estimated time/price limits.

• Vehicle Bob (Wants to be Faster/Pay for Rights of Way) This car's passenger made a preference selection to pay for a ride more money but arrive faster, with a larger maximum estimated price limit - auction winner

• Vehicle Charlie (Wants to be Faster/Pay for Rights of Way) This car's passenger made a preference selection to pay for a ride more money but arrive faster, with a smaller maximum estimated price limit - auction loser

• Alice is in the left lane. Charlie in the Right Lane follows Bob.
• Both Bob and Charlie want to move to the left lane and sending that request to Alice.
• Alice sets the minimum price she is willing to accept to give the rights of way (slow down and let either Bob or Charlie in the left lane )
• Bob submits the maximum price he is willing to pay for space
• Charlie submits the maximum price he is willing to pay for space
• Vickery auction is conducted.
• Auction results revealed
• Bob wins the auction
• Alice slows down to let Bob take place in front of her in the left lane

1. Install Nix package manager nixos.org/nix,
2. Download this project

git clone git@github.com:airalab/mobi_grand_challenge.git

3. Build each package you would like to launch

nix build -f $PACKAGE_NAME/release.nix

4. Source executables path from result directory

source ./result/setup.bash

5. Launch packages you need

roslaunch $PACKAGE_NAME $LAUNCHFILE_NAME

We need two AIRA services to communicate with Robonoimcs network

1. First launch robonomics_liability node to connect with Robonomics network providers

source ./result/setup.bash
source ./liability.sh

2. Then launch ethereum_common node to have a ROS API to web3

source ./result/setup.bash
source ./ethereum_common.sh
