Unmanned Surface Vehicles (USVs) have limitless applications in civil, commercial and defence environments. Development of USVs is an ongoing and exciting field, and modern advances in computing technology give more creative power to the engineer(s). This paper aims to briefly outline the current state of USV robot technology, and the development of a USV concept design to meet the primary goals of...
The advancement in technology nowadays has improved learning methods that are beginning to override the traditional methods. Augmented Reality (AR) is one such technology that has seen many applications in education. This paper describes how an Immersive Augmented Reality (iAR) application in conjunction with a book, can act as a new smart learning method by engaging as many of the user's senses and...
This article proposes a new design of a 3D unfolded/tightened mechanism based on the spine structure of golden tree snake, which can realize torsion and bending. Inspired by golden tree snake vertebrae space deformation characteristics, analyzing the anatomy characteristics of the golden tree snake spine bone and muscle distribution characteristics, The bionic mechanism and drive unit can drive the...
We present a model of simple cognitive agents, called “creatures”, and their learning process, a type of “social observational learning”, that is each creature learns from the behaviour of other creatures. The creatures may experience fear and/or desire, and are capable of evaluating if a strategy has been applied successfully and of applying this strategy again with small changes to a similar but...
In this paper, a model of influence of a tumor on the contact pressure for medical palpation training system is proposed. In this model, the contact pressure between a fìnger and a tissue including tumor is obtained from the contact pressures between finger and normal tissue and between normal tissue and tumor. Verification via FEM simulation showed that the proposed model can represent the influence...
Objects with non-Lambertian reflecting surfaces suffer severe appearance changes according to the change of observer's angle of view. Thus it is difficult to obtain a consistent object model. This paper addresses the problem of bin picking for such objects without using explicit object models. Due to the above-mentioned reasons, traditional pattern matching approaches are difficult to apply. Furthermore,...
The Virtual Space Robotics Test bed currently being developed serves as a decision support system in various space mission scenarios like e.g. Rendezvous and docking (RvD) and planetary landing and exploration. In the scope of the research project it is used for the generation and evaluation of images, acquired by a planetary lander during the descent phase. Therefore, camera characteristics and lighting...
Precision agriculture (PA) is nowadays one of the main strategies to fulfill the increasing food demand in the world. PA was defined as the set of technologies and procedures employed to optimize the agriculture production system. This article evaluate three types of rovers to be applied in precision agriculture, they are type Shrimp, Crab and Rocker Bogie. These rovers are modeled and simulated using...
Intelligent object manipulation is critical for a robot to effectively operate in a household environment. There are many grasp planners that can estimate grasps based on object shape, but these approaches often perform poorly because they miss key information about non-visual object characteristics. Object model databases can account for this information, but existing methods for database construction...
A rail-guided robotic system is currently being designed for the inspection of ballast water tanks in ships. This robotic system will manipulate sensors toward the interior walls of the tank. In this paper, the influence of rail compliance on the end-effector position error due to ship movement is investigated.
This article focuses on the problem of modifing the standard face identification approach for use in small-scale social dynamic environments, by focusing on adaptability rather than robustness. A design of adaptive face identification system is presented, along with the employed methods of online learning. The problem of ensuing bias-variance dilemma of an adaptive system is described and solved....
The paper presents an analysis of dynamic singularities in n-link pendulum-like models that are controlled using input-output feedback linearisation. The dynamic singularities are caused by the decoupling matrix being singular for particular configurations. The examples include 3-link planar pendulum, 3-link 3D pendulum and a simplified humanoid-like robot model. Partial stabilisation results are...
Mobile devices contain both personal as well as business data. Data security is a challenging issue in the era of mobile cloud computing. These Data needed to be protected from semi-trusted public cloud storage. In this paper, we have proposed an efficient and secure sharing of mobile device data using cloud storage. Blowfish algorithm is used for data encryption. We have developed a prototype application...
To prevent the failure of peg-in-hole assembly tasks involving geometrically complex parts, a force control-based assembly strategy that takes geometric information into account is required. Therefore, in this study, we propose an assembly strategy for complex-shaped parts which performs force control based on visually-obtained geometric information and CAD models. CAD models are used to obtain geometric...
Our research focuses on the development of a socially assistive robot to provide cognitive and social stimulation during meal-time scenarios in order to promote proper nutrition amongst the elderly. In this paper, we present the design of a novel automated affect recognition and classification system that will allow the robot to interpret natural displays of affective human body language during such...
The paper deals with an effective approach of the robust controller design, based on the fuzzy logic. We developed algorithms with variable sampling for trajectorytracking. The proposed controller design and sampling algorithms are verified on the case study of the chosen mechatronic system. All numerical and graphical results are obtained in Co-simulation of combination two different modeling systems...
Percutaneous coronary intervention is the gold standard to coronary diseases in the past decades due to much less trauma and quick recovery. However, due to the traits of minimal invasiveness, clinicians have to defeat the difficulties in eye-hand coordination during the procedure, which also makes it a non-trivial task in the catheterization lab. The computer-aided surgical simulation is designed...
One of the greatest challenges in automated planning in industrial environments is to create the link between a real world scenario and symbolic representations that are used by a planner. In this paper we describe an approach to interface a planner with a close-to-reality simulation system. By using this approach, we move the problematic interface with a physical scenario to the simulation system,...
Because of the instability and the complexity of the communication between the ground and the space, the teleoperation system faces many problems which can lead to operation failure. In order to enhance the success probability and reduce the unnecessary cost, the predication simulation system based on virtual reality is developed in this paper. The teleoperation command could be done in the system...
His work considers path-planning processes for manipulation tasks such as assembly, maintenance or disassembly in a Virtual Reality (VR) context. The approach consists in providing a collaborative system associating a user immersed in VR and an automatic path planning process. It is based on an novel environment model containing semantic, topological and geometric information and an original planning...
