Intermediate Meeting
- French language course Mon 31 October - Fri 4 November time: 9am - 1pm
Meeting 15/11/2016
- Continued literature research
- Started first web application for smart contracts (http://164.15.10.140/) with very basic functionality:
- Robots can be added to the swarm
- Miner can issue a premium in Ether as incentive for removing oil
- Oil can be removed by pressing a button -> sender gets rewarded
- Experimented a bit with ARGoS
- Discussed points during the meeting:
- I need a convincing problem/application that absolutely requires the blockchain (could be very different from the oil spill removal task)
- Look into PoW/PoS/PoX algorithms and see which one is best for robot swarms (also look into "Physical Proof of Work"); since robots are computationally rather limited, we need a clever consensus algorithm, otherwise, an attacker could easily perform a 51% attack; also find out which cryptocurrencies use which algorithm; see if it is possible to switch to PoS in Ethereum
- Investigate possibilities for light clients (e.g., each city/organization could have a node that maintains the blockchain and the corresponding robots just run light clients)
- I can use the footbot simulation for now but will probably use the e-puck in the real experiments
Meeting 22/11/2016
- Application Scenario
- Proof-of-X
- Created simple interface between ARGoS and Ethereum node
- TODO: Find out, which application scenario is suited for blockchain technology (for example by reading Swarm robotics: a review); see if Amanda's paper is relevant
Intermediate Meeting 25/11/2016
- Discussed Collective decisions
Meeting 29/11/2016
- Finished Week 1 of Coursera course
- Started ARGoS simulation for the collective decisions scenario (centralized version):
- 10 robots, each robot has an account/address with some ETH
- Robots with id 0 - 3: send opinion red; Robots with id 4 - 9: send opinion green
- If a robot detects a wall or another robot it sends its opinion via the smart contract
- After a random amount of time an epoch is finished, the majority opinion is determined, and the counters for red and green are set back to 0
- TODO:
- Make voting only possible if 1 ETH is send with the transaction
- Distribute ETH after an epoch is finished
- Base opinions on sensor inputs
- Implement strategies for changing opinions (e.g., majority opinion, voter model)
Meeting 7/12/2016
- Implemented decentralized ARGoS/Ethereum framework
- Each robot is an Ethereum node
- Some are miners (currently, only one is a miner)
- Only robots that are physically close to each other are connected to each other via their Ethereum nodes
- TODO:
- Transfer simple scenario to collective decision scenario
- Transfer framework to the cluster (and see if it is possible at all, since the processes have to talk to each other; maybe reserve some fixed cluster nodes)
- Looked at Davide's code and Master's thesis
- Answer Pedro (Innoviris funding)
Meeting 13/12/2016
- Prototype of collective decision scenario with Epucks in ARGoS
- Next steps:
- Transfer to cluster (first steps are done)
- Improve voting strategies (e.g., payed voting, direct modulation, ...)
