Projects

TODO

  • 30/1/2017
    • Implement majority voting and voter model in smart contract
    • Compare classical approach and secure approach (run experiments)
      • Answer question 1: "What do we get more?"
      • Answer question 2: "What can we do in terms of attacks and robustness?"
    • Finish FNRS proposal (definitely before 16th, since Marco might not be here from 17-23 Feb.)
    • Possible further improvements: use signal strength (range of the transmitter) as modulation strategy
    • Next meeting 7/2/2017 10am

Lab Responsibilities

  • IRIDIA server maintenance

Tutorials

Literature

See separate page

FRIA

Meetings

Meeting 27/9/2016

  • Continue literature research (read papers mentioned in FRIA proposal)
  • Find out which labs are doing blockchain / cryptocurrency / cryptography research (see Google Docs)

Meeting 4/10/2016

Meeting 18/10/2016

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

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, ...)

Meeting 19/12/2016

  • Transferred framework to cluster
  • Conducted some experiments
  • Robots are always mining now
  • MAJORITY VOTING: black is: 664 white is: 1032 -> Choosing white

Meeting 12/1/2017

Meeting 24/1/2017

Date?! Meeting

  • Make scenarios more similar (non-secure approach vs. blockchain approach) - comparison

Next Meeting
