Kinova modular robot arms for service robotics applications

This article presents Kinova's modular robotic systems, including the robots JACO2 and MICO2, actuators and grippers. Kinova designs and manufactures robotics platforms and components that are simple, sexy and safe under two business units: Assistive Robotics empowers people living with disabilities to push beyond their current boundaries and limitations while Service Robotics empowers people in industry to interact with their environment more efficiently and safely. Kinova is based in Boisbriand, Québec, Canada. Its technologies are exploited in over 25 countries and are used in many applications, including as service robotics, physical assistance, medical applications, mobile manipulation, rehabilitation, teleoperation and in research in different areas such as computer vision, artificial intelligence, grasping, planning and control interfaces. The article describes Kinova's hardware platforms, their different control modes (position, velocity and torque), control features and possible control interfaces. Integration to other systems and application examples are also presented

Systems of Geo Positioning of the Mobile Robot

Article is devoted to the analysis of opportunities of electronic instruments, such as a gyroscope, the accelerometer, the magnetometer together, the video system of image identification and system of infrared indicators during creation of system of exact positioning of the mobile robot. Results of testing and the operating algorithms are given. Possibilities of sharing of these devices and their association in a single system are analyzed. Conclusions on development of opportunities and elimination of shortcomings of the received end-to-end system of positioning of the robot are drawn

Robot navigation and target capturing using nature-inspired approaches in a dynamic environment

Path Planning and target searching in a three-dimensional environment is a challenging task in the field of robotics. It is an optimization problem as the path from source to destination has to be optimal. This paper aims to generate a collision-free trajectory in a dynamic environment. The path planning problem has sought to be of extreme importance in the military, search and rescue missions and in life-saving tasks. During its operation, the unmanned air vehicle operates in a hostile environment, and faster replanning is needed to reach the target as optimally as possible. This paper presents a novel approach of hierarchical planning using multiresolution abstract levels for faster replanning. Economic constraints like path length, total path planning time and the number of turns are taken into consideration that mandate the use of cost functions. Experimental results show that the hierarchical version of GSO gives better performance compared to the BBO, IWO and their hierarchical versions.Comment: 8 pages, 8 figure

Path Creation by Continuous Flocking as an Example of a Morphogenetic Programming Language

Artificial morphogenesis uses processes inspired by embryology to control massive swarms of robots to assemble complex physical structures. First, we use an example morphogenetic program to illustrate a prototype implementation of morphgen, a morphogenetic programming language. The syntax and semantics are described informally as illustrated by the example program, which is included in its entirety in an appendix. Another appendix includes a complete formal grammar for the current version of the language. Next, we describe the results of a series of experiments with the program, which simulates a continuous swarm of microscopic agents creating paths from an origin to a destination while avoiding obstacles. We present the effects of various parameters and of alternative ways of accomplishing particular purposes

Ergonomic Risk Assessment on Welding Practical Work on learning process at Malaysia polytechnic diploma of engineering programme

Practical work is part of the compulsory process of learning for any engineering student in polytechnic Malaysia. This study focuses on the ergonomic risk assessment during the practical work for Malaysian Polytechnic for mechanical diploma programme. Consequently, it is also implemented to identify potential harm caused by ergonomic risk factors. This study uses quantitative method through the Cornell Musculoskeletal Discomfort Questionnaire (CMQ) framework and is followed by a Rapid Entire Body Assessment (REBA). The instruments used are measuring tape, smartphones for recording audio and video as well as digital images, assessment checklists (CMQ and REBA), personal protective equipment, goniometers and weights scale. Based on the study, all elements of value provide high level risk score results and require ergonomic risk control. Therefore, it is recommended to review the body's posture and improve the techniques during the weld practical work process to reduce ergonomic risk factors
