A new 3D positioning algorithm for low cost robots is proposed. The algorithm is based on a Finite State Machine to estimate the position and orientation of the robot. The system sets dynamically the parameters of the algorithm and makes it independent of the noise in the sensors. The algorithm has been tested for differential wheel drive robots, however it can be used with different types of robots...

In this paper design of improved vision sensing manipulator to recognize desired components in unstructured assembly system is presented. The proposed sensor based intelligent robotic manipulator can be used to solve high-dimensional problems manipulate and...
Robotics has become a rapidly growing science that will enter the life of all classes of people in a few years. That is why we have tried to work in this field. The project that we are going to describe here is a robotic rescue team that uses its designed systems and utilized detection methods to help people and help rescuers to accurately detect victims when natural disasters such as floods and earthquakes...
In this article, a step-walker robot is introduced. In recent years too many explorer and moving robots are designed and manufactured. These kinds of robots need a mechanism for climbing stairs or steps to explore and discover all sections of a building. This introduced mechanism is an optimum mechanism in terms of energy consumption while climbing a step or stair with a specific altitude. The robot...
When the robot appears, various researches on it have been coming out one after the other and changing rapidly. The robotics is refined day after day. Especially in the recent decades, with the emergence and developments of internet and the computers, it makes a remarkable progress and reaches an unprecedented level. The robot is of wide applications because of the rapid developments of robotics....
Cyber-Physical Systems require the development of security models at cloud interacting with physical systems. The current research discusses the security requirements in the future engineering systems includes the state of security in cloud cyber-physical systems, and a security model in sensor networks in relation to cyber-physical systems. In addition, we develop a model to transfer the packets...
This paper presents a combined control system for mobile robot. The developed system allows to teleoperate a mobile robot and switches to autonomous movement when the connection with the mobile robot is lost. To create this control system the comparative analysis of existing sensors was performed, based on this analysis the sensors for localization robot were chosen, the virtual model of the 4-wheeled...
This paper presents a new theoretical development and modelling related to the requirement of the minimum number of sensors necessary for slippage prevention in robotic grasping. A fundamental experimental investigation has been conducted to support the newly developed postulate. A series of basic experiments proved that it is possible to evaluate the contributions of various sensors to slippage prevention...
Surveillance systems are in constant development and its dependence of humans although dwindling, it is still significant. On the other hand a constant evolution and adaptation of robots to perform tasks traditionally performed by humans it is also been witnessed. Using the advantage of these fields an architecture and a protocol to facilitate the integration of an autonomous robot as active agent...
In this paper we present the new version of the LSMaker Robot, an educational platform designed by La Salle — Ramon Llull University to be used as facilitator of acquisition of concepts in all engineering curricula and, at the same time, a new companion as a robotic classmate. The new version of the LSMaker, named LSMaker EV1, changes from a full customized to an open source Arduino-based hardware...
The hydraulic robot arm consists of two major parts: first is a human arm movement sensing and transmitting section, and the second is a receiving section and hydraulic robot arm. For sensing, linear potentiometers have been used and the voltage drop across each potentiometer is modeled. The control signals have been generated through CC430F6137 microcontroller and sent wirelessly. On the other end,...
Assistive technology is an emerging research area, where adaptable devices can be developed to help older people to achieve independence in their daily activities. This paper presents the design and development of a wearable wireless obstacle detection system suitable for the elderly and visually impaired people. The proposed system is capable of detecting obstacles located up to 1.5 meter from the...
A tracked crawler robot using body heat detection and a purpose built analogue tracking circuit is designed in this work. The infrared detection module consists of a single dual element pyroelectric infrared sensor. The drive and steering control system is designed using a single chip 74HCXX Quad 2-input NAND gate as the logic controller and providing constant forward propulsion whilst in real time...
Robotics has become a fundamental tool in many areas like education, industry, entertainment, medicine, research, among others. This paper illustrates some of the main approaches that have been taken to implement robotics in education and among them is TEAC2H-RI (Technology, Engineering And sCience eduCation through Human-Robot Interaction). It has been used for teaching subjects such as mathematics...
The intention of designing a robot is to facilitate the human beings through giving security and working as a helping hand through reprieving. The technology used in this rescue and security robot has a number of important features such as robotic car control by cell phone, automatically avoiding obstacles in its way. It can sense gas, smoke and provide an alert through text messaging. The robot can...
This paper provides an overview of the sensor network and mounting hardware used to convert a commercially available powered wheelchair into a semi-autonomous wheelchair. Emphasis is placed on modular design and ease of use. Although the sensor packages are used for the semi-autonomous navigation of a powered wheelchair, the sensor network presented has the potential to be used in a number of different...
This paper introduces the multiple source Multiple Destination Robot (MDR-1) having the ability to choose a desired line among multiple lines autonomously. Every line has different colors as their identities. The robot can differentiate among various colors and choose a desired one to find its target. Unlike any other simple line follower robot, this robot can be considered as a true autonomous line...
This article explains the development of a cooperative robotic system, using three mobile platforms Lego Mindstorms nxt 2.0 as a convoy moving through an established route. These robots have actuators that allow the displacement, measurement of their environment and transmission an infrared signal that allows them to establish a wireless communication according to the orders assigned by the first...
The development of each mobile robot's control system is bounded up with the creation of sophisticated systems to solve problems with the communication between the individual modules, working with different peripheral devices, and execution of laws of motion. The division of the tasks into two levels solves these problems to a great extent, but imposes specific requirements on the integration of the...
This paper discusses the issues on the logical foundations of knowledge representation for intelligent autonomous agents. We analyze the limitations of the mathematical logic approaches in knowledge representations and show that classical semantic interpretations are not suitable for expressing the autonomous knowledge of agents. We propose a novel logical framework in which the semantic interpretations...
