Assistive robotic device: evaluation of intelligent algorithms
Assistive robotic devices can be used to help people with upper body
disabilities gaining more autonomy in their daily life. Although basic motions
such as positioning and orienting an assistive robot gripper in space allow
performance of many tasks, it might be time consuming and tedious to perform
more complex tasks. To overcome these difficulties, improvements can be
implemented at different levels, such as mechanical design, control interfaces
and intelligent control algorithms. In order to guide the design of solutions,
it is important to assess the impact and potential of different innovations.
This paper thus presents the evaluation of three intelligent algorithms aiming
to improve the performance of the JACO robotic arm (Kinova Robotics). The
evaluated algorithms are 'preset position', 'fluidity filter' and 'drinking
mode'. The algorithm evaluation was performed with 14 motorized wheelchair's
users and showed a statistically significant improvement of the robot's
performance.Comment: 4 page

AltURI: a thin middleware for simulated robot vision applications
Fast software performance is often the focus when developing real-time vision-based control applications for robot simulators. In this paper we have developed a thin, high performance middleware for USARSim and other simulators designed for real-time vision-based control applications. It includes a fast image server providing images in OpenCV, Matlab or web formats and a simple command/sensor processor. The interface has been tested in USARSim with an Unmanned Aerial Vehicle using two control applications; landing using a reinforcement learning algorithm and altitude control using elementary motion detection. The middleware has been found to be fast enough to control the flying robot as well as very easy to set up and use
Flora robotica -- An Architectural System Combining Living Natural Plants and Distributed Robots
Key to our project flora robotica is the idea of creating a bio-hybrid system
of tightly coupled natural plants and distributed robots to grow architectural
artifacts and spaces. Our motivation with this ground research project is to
lay a principled foundation towards the design and implementation of living
architectural systems that provide functionalities beyond those of orthodox
building practice, such as self-repair, material accumulation and
self-organization. Plants and robots work together to create a living organism
that is inhabited by human beings. User-defined design objectives help to steer
the directional growth of the plants, but also the system's interactions with
its inhabitants determine locations where growth is prohibited or desired
(e.g., partitions, windows, occupiable space). We report our plant species
selection process and aspects of living architecture. A leitmotif of our
project is the rich concept of braiding: braids are produced by robots from
continuous material and serve as both scaffolds and initial architectural
artifacts before plants take over and grow the desired architecture. We use
light and hormones as attraction stimuli and far-red light as repelling
stimulus to influence the plants. Applied sensors range from simple proximity
sensing to detect the presence of plants to sophisticated sensing technology,
such as electrophysiology and measurements of sap flow. We conclude by
discussing our anticipated final demonstrator that integrates key features of
flora robotica, such as the continuous growth process of architectural
artifacts and self-repair of living architecture.Comment: 16 pages, 12 figure
A Bibliometric Perspective Survey of IoT controlled AI based Swarm robots
Robotics is the Ânew-age domain of technology that deals with bringing a collaboration of all disciplines of sciences and engineering to create a mechanical machine that may or may not work entirely independently but definitely focuses on making human lives much easier. It has repeatedly shown its ability to change lives at home and in the industry. As the field of robotics research grows and reaches new worlds, the military is one area where advances can have a significant impact, and the government is aware of this. Military technology has come a long way from the days where soldiers had to walk into traps, putting their own lives in danger for their fellow soldiers, to today, when soldiers have robots walk into the same traps with possibility and result of zero human casualties. High-risk military operations such as mine detection, bomb defusing, fighter pilot aviation, and entering enemy territory without complete knowledge of what is to come are all tasks that can be programmed in a way that makes them accustomed to scenarios like these, either by intensive machine learning algorithms or artificially intelligent robot systems. Military soldiers are human capital; they are not self-driving robots; they are living beings with emotions, fears, and weaknesses, and they will almost always be unreliable as compared to computers and robots. They are easily affected by environmental effects and are vulnerable to external influences. The government\u27s costs for deployed troops, such as training and salaries, are extremely high. As a result, the solution is to build AI robots for defence operations that can sense, collect data by observing surroundings as any human soldier would, and report it back to a workstation where it can be used for strategy building and planning on what the next step should be during a mission, thus making the army better prepared for any kind of trouble that might be on their way. In this paper, the survey and bibliometric analysis of AI-based IoT managed Swarm Robots from the Scopus repository is discussed, which analyses research by area, notable authors, organizations, funding agencies and countries. Statistical analysis of literature published as journals, articles and papers that aids in understanding the global influence of publication is called Bibliometric analysis. This paper is a thorough analysis of 84 research papers as obtained from the Scopus repository on the 3rd of April 2021. GPS Visualizer, Gephi, wordcloud, and ScienceScape are open source softwares used in the visualization review. As previously mentioned, the visualization assists in a quick and easy interpretation of the different viewpoints in a particular study domain pursuit
Automatic Curriculum Learning For Deep RL: A Short Survey
Automatic Curriculum Learning (ACL) has become a cornerstone of recent
successes in Deep Reinforcement Learning (DRL).These methods shape the learning
trajectories of agents by challenging them with tasks adapted to their
capacities. In recent years, they have been used to improve sample efficiency
and asymptotic performance, to organize exploration, to encourage
generalization or to solve sparse reward problems, among others. The ambition
of this work is dual: 1) to present a compact and accessible introduction to
the Automatic Curriculum Learning literature and 2) to draw a bigger picture of
the current state of the art in ACL to encourage the cross-breeding of existing
concepts and the emergence of new ideas.Comment: Accepted at IJCAI202
Synopsis of an engineering solution for a painful problem Phantom Limb Pain
This paper is synopsis of a recently proposed solution for treating patients who suffer from Phantom Limb Pain (PLP). The underpinning approach of this research and development project is based on an extension of “mirror box” therapy which has had some promising results in pain reduction. An outline of an immersive individually tailored environment giving the patient a virtually realised limb presence, as a means to pain reduction is provided. The virtual 3D holographic environment is meant to produce immersive, engaging and creative environments and tasks to encourage and maintain patients’ interest, an important aspect in two of the more challenging populations under consideration (over-60s and war veterans). The system is hoped to reduce PLP by more than 3 points on an 11 point Visual Analog Scale (VAS), when a score less than 3 could be attributed to distraction alone
What Are We Augmenting? A Multidisciplinary Analysis of AI-based Augmentation for the Future of Work.
While augmentation is commonly presented as a desirable path in AI development and implementation, we have not yet found a shared definition for this concept. As the verb “to augment” needs to be followed by a target, we raise the question: What is augmented with AI? Building on a literature review of the augmentation narratives in five different disciplines – i.e., labor economics, computer science, philosophy, management, and information systems – we identify eleven distinct augmentation perspectives taken by scholars of those fields, including the underlying theoretical concepts that indicate what is intended to be augmented. This paper contributes to theory by “going beyond augmentation as collaboration” and helping us to move “towards collaboration for augmentation”
Biblio-Analysis of Cohort Intelligence (CI) Algorithm and its allied applications from Scopus and Web of Science Perspective
Cohort Intelligence or CI is one of its kind of novel optimization algorithm.
Since its inception, in a very short span it is applied successfully in various
domains and its results are observed to be effectual in contrast to algorithm
of its kind. Till date, there is no such type of bibliometric analysis carried
out on CI and its related applications. So, this research paper in a way will
be an ice breaker for those who want to take up CI to a new level. In this
research papers, CI publications available in Scopus are analyzed through
graphs, networked diagrams about authors, source titles, keywords over the
years, journals over the time. In a way this bibliometric paper showcase CI,
its applications and detail outs systematic review in terms its bibliometric
