Available in PDF, EPUB and Kindle. Book excerpt: Objective: Develop a mobile manipulator that one person can use to lift and maneuver 50- to 600-pound loads. It can be used in maintenance shops and mines to reduce lifting accidents. Background: Lifting heavy items is one of the leading causes of injury in the workplace. Mine Safety and Health Administration statistics showed that, in 2004, back injuries accounted for over 20% of all injuries (1,699 cases) and resulted in 110,000 lost days of work. Forty-one percent of those injuries resulted from materials-handling or maintenance activities. In addition to back injuries, lifting injuries include hernias, ruptures, sprains, and strains resulting from losing control of the item being lifted. Factors associated with accidents are weight of the item being lifted, awkward postures, inadequate handholds, and the working environment itself. High accident rates were noted when lifting items that ranged from 50 to 600 pounds, particularly in tight working quarters where maneuverability was critical. Research indicated that a mobile lifting arm would eliminate many lifting accidents in environments where other lifting devices (fork lifts, overhead cranes, mobile A-frames) would not be practical. NIOSH has built a first-generation mobile manipulator unit designed to be used on hard, level floors such as in a shop. The complexity of motion, number of moving parts, compact design, and design constraints of the manipulator required advanced computer-aided design work. As a result of the design work, thirty-eight claims are included in the patent applications. NIOSH will be conducting field trails and working with manufacturers to put the manipulator into industrial use. Operating the Mobile Manipulator: The mobile manipulator is a self-propelled, battery-powered lifting arm mounted on a central turret that allows full rotation. To operate, a worker trams the unit into position for the lifting task and deploys stab-jacks for leveling and stabilizing. The linkage system is designed to allow the operator to guide heavy loads precisely; for example, sliding a 200-pound gear assembly onto a shaft where alignment and damage to equipment are critical considerations. Although the operator needs only 10 pounds of pressure to lift the load, the momentum of moving the load can create a need for braking, and so the operator has hand brakes to stop arm and turret movement immediately. The ease of tramming and steering, along with the small size of the manipulator, allows operators to stow the unit conveniently close by without interfering with ongoing operations."--NIOSHTIC-2.
Download or read book Design and Implementation of a Closed loop Mobile Manipulator Control System written by Omar Aboul-Enein and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mobile manipulators, which integrate a robotic manipulator with an automatic-autonomous mobile base, have the potential to augment automation by combining the capability of navigation with complex manipulation to support unstructured and dynamic environments. Targeted applications include manufacturing large-scale parts commonly encountered in the aerospace, energy, shipbuilding, and transportation sectors. While autonomous mobility no longer restricts the robotic manipulator to working at a single, rigidly fixtured workstation or work-piece, the increased flexibility introduces new sources of position and orientation uncertainty, and manufacturing processes of large-scale parts with complex, curved surfaces require high repeatability and accuracy. A standardized measurement methodology, including a configurable measurement artifact to simulate dynamic manufacturing operations, is being developed to identify and evaluate these sources of performance uncertainty. As part of this methodology and associated test methods development, this work details the design and prototype implementation of a closed-loop mobile manipulator control system that integrates feedback from an optical tracking system. Development of the control system presents a new test implementation to demonstrate the performance evaluation of mobile manipulation performance in application scenarios where the workstation or work-piece is physically disturbed during operation or where rapid registration between distant locations along the same work-piece is required. This work will promote advances in control scheme development by providing a standardized, reproducible test method for evaluation in a variety of simulated application spaces.

Download or read book Aerial Manipulation written by Matko Orsag and published by Springer. This book was released on 2017-09-19 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text is a thorough treatment of the rapidly growing area of aerial manipulation. It details all the design steps required for the modeling and control of unmanned aerial vehicles (UAV) equipped with robotic manipulators. Starting with the physical basics of rigid-body kinematics, the book gives an in-depth presentation of local and global coordinates, together with the representation of orientation and motion in fixed- and moving-coordinate systems. Coverage of the kinematics and dynamics of unmanned aerial vehicles is developed in a succession of popular UAV configurations for multirotor systems. Such an arrangement, supported by frequent examples and end-of-chapter exercises, leads the reader from simple to more complex UAV configurations. Propulsion-system aerodynamics, essential in UAV design, is analyzed through blade-element and momentum theories, analysis which is followed by a description of drag and ground-aerodynamic effects. The central part of the book is dedicated to aerial-manipulator kinematics, dynamics, and control. Based on foundations laid in the opening chapters, this portion of the book is a structured presentation of Newton–Euler dynamic modeling that results in forward and backward equations in both fixed- and moving-coordinate systems. The Lagrange–Euler approach is applied to expand the model further, providing formalisms to model the variable moment of inertia later used to analyze the dynamics of aerial manipulators in contact with the environment. Using knowledge from sensor data, insights are presented into the ways in which linear, robust, and adaptive control techniques can be applied in aerial manipulation so as to tackle the real-world problems faced by scholars and engineers in the design and implementation of aerial robotics systems. The book is completed by path and trajectory planning with vision-based examples for tracking and manipulation.

Available in PDF, EPUB and Kindle. Book excerpt: Aerial robotic manipulation integrates concepts and technologies coming from unmanned aerial systems and robotics manipulation. It includes not only kinematic, dynamics, aerodynamics and control but also perception, planning, design aspects, mechatronics and cooperation between several aerial robotics manipulators. All these topics are considered in this book in which the main research and development approaches in aerial robotic manipulation are presented, including the description of relevant systems. In addition of the research aspects, the book also includes the deployment of real systems both indoors and outdoors, which is a relevant characteristic of the book because most results of aerial robotic manipulation have been validated only indoor using motion tracking systems. Moreover, the book presents two relevant applications: structure assembly and inspection and maintenance, which has started to be applied in the industry. The Chapters of the book will present results of two main European Robotics Projects in aerial robotics manipulation: FP7 ARCAS and H2020 AEROARMS. FP7 ARCAS defined the basic concepts on aerial robotic manipulation, including cooperative manipulation. The H2020 AEROARMS on aerial robot with multiple arms and advanced manipulation capabilities for inspection and maintenance has two general objectives: (1) development of advanced aerial robotic manipulation methods and technologies, including manipulation with dual arms and multi-directional thrusters aerial platforms; and (2) application to the inspection and maintenance.
