A wearable general-purpose solution for Human-Swarm Interaction
Swarms of robots will revolutionize many industrial applications, from targeted material delivery to precision farming. Controlling the motion and behavior of these swarms presents unique challenges for human operators, who cannot yet effectively convey their high-level intentions to a group of robots in application. This work proposes a new human-swarm interface based on novel wearable gesture-control and haptic-feedback devices. This work seeks to combine a wearable gesture recognition device that can detect high-level intentions, a portable device that can detect Cartesian information and finger movements, and a wearable advanced haptic device that can provide real-time feedback. This project is the first to envisage a wearable Human-Swarm Interaction (HSI) interface that separates the input and feedback components of the classical control loop (input, output, feedback), as well as being the first of its kind suitable for both indoor and outdoor environments
RoboChain: A Secure Data-Sharing Framework for Human-Robot Interaction
Robots have potential to revolutionize the way we interact with the world
around us. One of their largest potentials is in the domain of mobile health
where they can be used to facilitate clinical interventions. However, to
accomplish this, robots need to have access to our private data in order to
learn from these data and improve their interaction capabilities. Furthermore,
to enhance this learning process, the knowledge sharing among multiple robot
units is the natural step forward. However, to date, there is no
well-established framework which allows for such data sharing while preserving
the privacy of the users (e.g., the hospital patients). To this end, we
introduce RoboChain - the first learning framework for secure, decentralized
and computationally efficient data and model sharing among multiple robot units
installed at multiple sites (e.g., hospitals). RoboChain builds upon and
combines the latest advances in open data access and blockchain technologies,
as well as machine learning. We illustrate this framework using the example of
a clinical intervention conducted in a private network of hospitals.
Specifically, we lay down the system architecture that allows multiple robot
units, conducting the interventions at different hospitals, to perform
efficient learning without compromising the data privacy.Comment: 7 pages, 6 figure
Personal Food Computer: A new device for controlled-environment agriculture
Due to their interdisciplinary nature, devices for controlled-environment
agriculture have the possibility to turn into ideal tools not only to conduct
research on plant phenology but also to create curricula in a wide range of
disciplines. Controlled-environment devices are increasing their
functionalities as well as improving their accessibility. Traditionally,
building one of these devices from scratch implies knowledge in fields such as
mechanical engineering, digital electronics, programming, and energy
management. However, the requirements of an effective controlled environment
device for personal use brings new constraints and challenges. This paper
presents the OpenAg Personal Food Computer (PFC); a low cost desktop size
platform, which not only targets plant phenology researchers but also
hobbyists, makers, and teachers from elementary to high-school levels (K-12).
The PFC is completely open-source and it is intended to become a tool that can
be used for collective data sharing and plant growth analysis. Thanks to its
modular design, the PFC can be used in a large spectrum of activities.Comment: 9 pages, 11 figures, Accepted at the 2017 Future Technologies

Secure Encoded Instruction Graphs for End-to-End Data Validation in Autonomous Robots
As autonomous robots become increasingly ubiquitous, more attention is being
paid to the security of robotic operation. Autonomous robots can be seen as
cyber-physical systems that transverse the virtual realm and operate in the
human dimension. As a consequence, securing the operation of autonomous robots
goes beyond securing data, from sensor input to mission instructions, towards
securing the interaction with their environment. There is a lack of research
towards methods that would allow a robot to ensure that both its sensors and
actuators are operating correctly without external feedback. This paper
introduces a robotic mission encoding method that serves as an end-to-end
validation framework for autonomous robots. In particular, we put our framework
into practice with a proof of concept describing a novel map encoding method
that allows robots to navigate an objective environment with almost-zero a
priori knowledge of it, and to validate operational instructions. We also
demonstrate the applicability of our framework through experiments with real
robots for two different map encoding methods. The encoded maps inherit all the
advantages of traditional landmark-based navigation, with the addition of
cryptographic hashes that enable end-to-end information validation. This
end-to-end validation can be applied to virtually any aspect of robotic
operation where there is a predefined set of operations or instructions given
to the robot

Grex: A Decentralized Hive Mind
Swarm Robotics (SR) faces a series of challenges impeding widespread adoption for real-world applications. Distributed Ledger Technology (DLT) has shown it can solve a number of these challenges. An experiment was conducted to showcase the resolution of these challenges. A search and rescue mission was simulated using drones coupled with single board computers and several simulated agents. Inter-agent communications were facilitated through DLT in a completely decentralized network. A frontend interface was built to demonstrate the ease with which information can be extracted from the system. This paper shows the feasibility of the application of DLT to SR-related challenges in a practical experiment. For future work, it is proposed to focus on more complex tasks through federated learning or inter-swarm communications, possibly through Cosmos
Robotic Services for New Paradigm Smart Cities Based on Decentralized Technologies
This article describes different methods of organizing robotic services for smart cities using secure encrypted decentralized technologies and market mechanisms鈥攁s opposed to models based on centralized solutions based (or not) on using cloud services and stripping citizens of the control of their own data. The basis of the proposed methods is the Ethereum decentralized computer with the mechanism of smart contracts. In this work, special attention is paid to the integration of technical and economic information into one network of transactions, which allows creating a unified way of interaction between robots鈥攖he robot economy. Three possible scenarios of robotic services for smart cities based on the economy of robots are presented: unmanned aerial vehicles (UAVs), environmental monitoring, and smart factories. In order to demonstrate the feasibility of the proposed scenarios, three experiments are presented and discussed. Our work shows that the Ethereum network can provide, through smart contracts and their ability to activate programs to interact with the physical world, an effective and practical way to manage robot services for smart cities
Self-employment for autonomous robots using smart contracts
The physical autonomy of robots is well understood both theoretically and
practically. By contrast, there is almost no research exploring a robot's
potential economic autonomy. In this paper, we present the first economically
autonomous robot -- a robot able to produce marketable goods while having full
control over the use of its generated income. In our proof-of-concept, the
robot is self-employed as an artist. It produces physical artistic goods and
uses blockchain-based smart contracts on the Ethereum network to autonomously
list its goods for sale in online auctions. Using the blockchain-based smart
contract, the robot then uses its income from sales to autonomously order more
materials from an online shop, pay for its consumables such as network fees,
and remunerate human assistance for support tasks. The robot also uses its
income to repay investor loans that funded its initial phase of production. In
these transactions, the robot interacts with humans as a peer, not as a tool.
In other words, the robot makes peer financial transactions with humans in the
same way that another human would, first as an investment vehicle, then as a
seller at an auction, and then as a shop customer and a client. Our
proof-of-concept is conducted as an in-lab experiment, but gives rise to an
important discussion of the legal implications of economically autonomous
robots, which under existing frameworks can already be embedded in corporate
entities that are classed as artificial persons.Comment: Discussion extended with the legal implications subsectio
Urban Swarms: A new approach for autonomous waste management
Modern cities are growing ecosystems that face new challenges due to the
increasing population demands. One of the many problems they face nowadays is
waste management, which has become a pressing issue requiring new solutions.
Swarm robotics systems have been attracting an increasing amount of attention
in the past years and they are expected to become one of the main driving
factors for innovation in the field of robotics. The research presented in this
paper explores the feasibility of a swarm robotics system in an urban
environment. By using bio-inspired foraging methods such as multi-place
foraging and stigmergy-based navigation, a swarm of robots is able to improve
the efficiency and autonomy of the urban waste management system in a realistic
scenario. To achieve this, a diverse set of simulation experiments was
conducted using real-world GIS data and implementing different garbage
collection scenarios driven by robot swarms. Results presented in this research
show that the proposed system outperforms current approaches. Moreover, results
not only show the efficiency of our solution, but also give insights about how
to design and customize these systems.Comment: Manuscript accepted for publication in IEEE ICRA 201
