Fish-as-a-Service (FaaS) is a business-to-business model offering monitoring services performed by a biomimetic fishlike drone. FaaS considers environmental, scientific, and business concerns when addressing marine monitoring, providing alternative methodology while preserving ocean resources. The key to FaaS is the ability to provide a low-cost, low-maintenance, high-endurance, agile sensor platform...
This paper presents a new under-actuated resilient robot that has the three recovery processes available, as we proposed elsewhere. The new feature with the proposed resilient robot is such that all the recovery strategies can be accomplished in a 2D plane instead of a 3D space, thus reducing the complexity of the recovery process. The robot also has the ability of switching between a fully-actuated...
This paper describes the mechanical design of a prototype of a 4 degree of freedom upper limb exoskeleton suit. A cable driven system actuated by an array of pneumatic muscles, located at the back of the suit, was implemented in the prototype. The developed design aims to enhance human upper body strength for applications ranging from the rehabilitation of stroke patients to enabling workers and soldiers...
A painting robot ARTCYBE is a machine developed to imitate an ability of a human painter to create realistic images with acrylic paints and a brush. In this paper a brushstroke rendering algorithm for this robot is presented. The algorithm converts a source bitmap image into a set of brushstrokes which we call a brushstroke map. The brushstroke map can be unambiguously transformed into a list of commands...
In manufacturing, the increasing involvement of autonomous robots in production processes poses new challenges on the production management. In this paper we report on the usage of Optimization Modulo Theories (OMT) to solve certain multi-robot scheduling problems in this area. Whereas currently existing methods are heuristic, our approach guarantees optimality for the computed solution. We do not...
The article focuses on designed construction of the exoskeleton, which significantly reproduces the kinematic structure and the range of joint movement of the human upper limb. The exoskeleton will able to control real objects i.e. loading crane, including force feedback. The designed device, composed of seven rotary joints, is equipped with the closed loop Bowden cable conduit system with linear...
The main goal of this study is to analyse the effects of combined transcranial direct current stimulation (tDCS) and wrist robot-assisted therapy in subacute stroke patients. Twenty-four patients were included in this study and randomly assigned to the experimental (EG) or control group (CG). All participants performed wrist robot-assisted training a) in conjunction with tDCS (real stimulation for...
Vanilla is among the most expensive and most produced spices in the world today. Hand pollination is required in most areas around the globe. Because of the amount of manual labour required for hand pollination automation should reduce the production cost and bring more organic vanilla to the spice market displacing adulterated products. A vanilla crane system for pollination was proposed and simulated...
Capitalizing on the latest developments in 5G and ultra-low delay networking as well as Artificial Intelligence (AI) and robotics, we advocate here for the emergence of an entirely novel Internet which will enable the delivery of skills in digital form. We outline the technical challenges which need to be overcome to enable such a vision, i.e., on the development of a 5G Tactile Internet, standardized...
Despite being well established in robotics, classical motor controllers have several disadvantages: they pose a high computational load, therefore requiring powerful devices, they are not easy to tune and they are not suited for neuroprosthetics. In contrast, bio-inspired controller do not transform the output of the controller therefore no delays are introduced and a smooth response is achieved;...
Modern robotics involves partial or complete automation systems, which in turn requires the presence of elements of artificial intelligence. That's why appears a necessity in system of pattern recognition.
In the context of a research project of the group for control engineering and automotive mechatronics from Ostfalia University a highly dynamic system comprising a spherical electrical drive is to be developed in a model based manner [1]. This system is to be used as the core actuation element of a service platform called the S-Mobile. The S-Mobile can be used for example as a service robot for interaction...
Robotics software systems have a large and domain-specific range of quality requirements that make development of reusable software a particular challenge. Frameworks and middleware have a major impact in this respect - on both quality characteristics and development effort. As framework design involves many tradeoffs, they have different quality and feature profiles - with no existing solution clearly...
This paper reports on a pilot project of limited scopeto create a pipeline for the computer programming industry. It comes at a time when the demand for software programmers exceeds the dwindling supply of competent learners with suitable skills. This growing skills gap requires a bold intervention to turn this situation around. Preliminary results from a user questionnaire indicate a positive reaction...
Meta-heuristic algorithms have been known to solve complex problems which were once considered difficult to solve. They produce an optimal or near optimal solution with reduced computational complexity and are thus are considered where deterministic algorithms produce inefficient solutions. Robotics has been a disciplinary field where artificial intelligence is bestowed to robots for them to perform...
Detection and tracking of moving objects in video is emerging in computer vision and robotics. Classification of objects in addition to the detection and tracking can lead to better understanding of the scene and helps in taking certain decisions in various applications. Classifying the objects based on the features like color, shape, size, speed, direction of objects in motion has numerous applications...
In a recent SIAM Journal on Control and Optimization article, our team analyzed the robustness of a class of adaptive three-dimensional curve tracking controls for free moving particles, using penalty functions and robustly forward invariant sets with maximum allowable perturbation bounds. This allowed us to track curves, identify unknown control gains, and provide predictable tolerance and safety...
Computer Science (CS) seems to be everywhere - in our smartphones, apps, cars, watches and so much more. It is integrated into almost every discipline and has a growing importance in our daily lives, yet even with top salaries, exciting companies, and promising careers, the job market remains underpopulated and under-representative of women. Though its applications are everywhere, CS is an often misunderstood...
Robotics has impacted many domains and industries. Robotics in education has been of particular interest to researchers and educationalists through the past decade. Various studies have confirmed that robots have had a positive impact on teaching skills in various subjects. In this paper, we develop and discuss a prototype for a robot language tutor. We use various vision techniques for behavior analysis...
Web-based learning plays a vital role in the modern education system, where different technologies are being emerged to enhance this E-learning process. Therefore virtual and online laboratories are gaining popularity due to its easy implementation and accessibility worldwide. These types of virtual labs are useful where the setup of the actual laboratory is complicated due to several factors such...
