  • Innovative development of a spherical parallel robot for upper limb
           rehabilitation
    • Authors: Calin Vaida, Nicolae Plitea, Giuseppe Carbone, Iosif Birlescu, Ionut Ulinici, Adrian Pisla, Doina Pisla
      Pages: 256 - 276
      Abstract: Post-stroke robotic rehabilitation is an ever increasing field of research that aims to offer custom care with maximised effectiveness. This paper presents the necessity of pursuing further improvements in said field as well as the factors that contributed towards the development of an innovative yet simple spherical-parallel robotic device targeting the rehabilitation of the upper human limb. A conceptual device entitled ASPIRE is proposed. The robotic system kinematics and singularities are derived to assert the robot functionality for the rehabilitation exercises. Moreover, two design structures are presented for the ASPIRE system, and motion simulations are performed.

  • Synthesis of precision flexible mechanisms using screw theory and beam
           constraints
    • Authors: Alejandro Gastón Gallardo, Martín Alejo Pucheta
      Pages: 277 - 304
      Abstract: The design of flexible parallel stages has recently been systematised for the three-dimensional space using screw theory. The relationships between the twists (motions), the wrench actuations, and constraint wrenches spaces can be manipulated by linear algebra. The use of flexible beams to constraint small motions leads to simple precision mechanisms. In a previous work by the authors, an analytical enumeration of twists and their reciprocal wrenches for any degree of freedom with zero and infinite pitches was presented and validated using finite element analysis. This work extends the methodology to account for screws with finite non-null pitches. Two synthesis problems are analytically calculated and validated using finite element analysis.

  • Matroid application to self-aligning mechanisms: enumeration and
           analysis
    • Authors: Andrea Piga Carboni, Henrique Simas, Daniel Martins
      Pages: 305 - 322
      Abstract: The study of mechanisms is one of the most important areas on which machine design relies. Research in mechanism can be roughly divided into two main problems: mechanism analysis and mechanism synthesis. This paper focuses on topology analysis of mechanism, by means of screw theory representation of mechanisms. Freedoms and constraints in mechanisms are thus described applying the Kirchhoff's laws adaptation to multibody systems proposed by Davies. Based on this modelling, overconstraint in mechanisms is analysed in terms of free motions and constraints. The self-aligning mechanisms kinematically equivalent to an overconstraint mechanism are investigated. Two new algorithms for enumerating all self-aligning kinematically equivalent mechanisms to an overconstrained one and for selecting an optimal self-aligning topology, based on a set of criteria, are proposed. All algorithms have been implemented in Sage software and run in polynomial time. Examples of applications are presented, and the results obtained are validated with literature cases.

  • Maximum isotropic force capability maps in redundant planar cooperative
           systems
    • Authors: Leonardo Mejia Rincon, Roberto Simoni, Juan Camilo Herrera, Henrique Simas, Daniel Martins
      Pages: 323 - 338
      Abstract: In robotics, the force capability is defined as the maximum wrench that can be applied (or sustained) by a manipulator. The concept of isotropic force capability appeared as a subset of the classic force capability and it was formally defined as the maximum magnitude of force that a robot can apply or support <i>in all directions</i> according to a given posture. A relevant condition which must be studied is when there is load distribution processes between cooperative robotic systems, e.g., when two or more arms are carrying the same load, if the load distribution fails, one of the arms may overload causing structural or material damage during the process. The main objective of this paper is to develop a method to determine the area in the workspace of a cooperative robotic system composed by two redundant planar serial manipulators (4R), which presents the maximum isotropic force capability. The isotropic force capability maps are generated for three different load's orientations and working modes.
      Keywords: isotropic force capability; cooperative robotic system; Davies' method; differential evolution algorithm; screw theory

  • A simplified model for friction compensation in precise feed drives
    • Authors: Fernando Villegas, Rogelio Hecker, Gustavo Flores
      Pages: 339 - 351
      Abstract: Friction is a complex phenomenon with negative effects on the precision of positioning systems. In this work, a single-state friction model for control purposes, aimed to simplify the implementation of control algorithms while keeping a good performance in friction compensation, is analysed. In particular, the model is capable or representing the Stribeck curve, rate independent presliding hysteresis with non-local memory and non-drifting behaviour. This model has been tested on an experimental setup based on a linear motor, and its performance is compared to that of the generalised Maxwell-slip model, showing better performance on the tracking error.

  • Global optimisation analysis for a planar redundant serial manipulator
    • Authors: Zijia Li, Mathias Brandstötter, Michael Hofbaur

      Abstract: A planar serial manipulator with three rotational joints (planar 3R) can be seen to be a kinematically redundant system if only the position of the end-effector is taken into account. A symbolic computation analysis reveals that kinematic singularities for such manipulators appear at the position of the end-effector where the number of real connected components changes. In addition, apart from the singularities at the boundaries of the workspace, all inner singularities have a symmetric characteristics such that one rotational angle equals to 180 degrees, which often corresponds to an excess of a joint limit with real industrial robots systems. A global optimisation with a cost function regarding the joint limits depended on configurations of planar serial 3R manipulators will be considered in this work in detail. We analyse and show the variation behaviour of the global minimisation among its workspace with a fixed end-effector or when the end-effector follows algebraic motions (for instance, algebraic curves in the special Euclidean group). This gives us new insights. First, the global minimum is not unique. Second, the global minimum could have a jump in the configuration set due to ambiguous minima.

  • Method and clinical validation of a kinetostatic model of the human knee

      Pages: 368 - 382
      Abstract: In this work is developed and validated a static model of the human knee, based on mechanism theory, to provide surgeons information that relates forces at the anterior cruciate ligament graft (ACL) with its fixing position. The methodology for the static model is based on reimplementing a pure kinematic knee model available in the literature. This kinematic model is redefined using Davies' method to obtain a static model that yields the forces at ligaments and condyles. The proposed static model is validated by simulation of a clinical application where numerical results are compared with physiological ones. The validation uses the forces of the ACL at selected insertion points as criteria. This aims to determine the graft insertion points, at femur, that best leads to the natural response of an intact knee. Results show the applicability of the method as a support tool for medical decision making in the preoperative planning.

  • Synthesis of epicyclic gear trains with one and two degrees of freedom
           from kinematic chains belonging to minimal sets
    • Authors: Marina Baldissera De Souza, Rodrigo De Souza Vieira, Daniel Martins
      Pages: 383 - 400
      Abstract: The enumeration of kinematic chains for epicyclic gear trains allows obtaining all the possible configurations from specified structural characteristics. However, the more complex becomes the desired structure, the greater the number of options to analyse in order to select the most suitable one, therefore, it is necessary a criterion to reduce this range of choices. The variety of kinematic chains and the concept of minimal sets can be used for this purpose. This paper enumerates the kinematic chains with zero variety for epicyclic gear trains with one and two degrees of freedom, and with up to four independent loops. Some epicyclic gear trains generated from the chains belonging to minimal sets are presented afterward, and the advantages of using zero variety chains are discussed.

  • Dynamic synthesis of energy-efficient mechanisms
    • Authors: Ferdinand Schwarzfischer, Mathias Hüsing, Burkhard Corves
      Pages: 401 - 417
      Abstract: Motion systems (MS) form part of many different production machines, for example weaving machines, printing machines or packaging machines. This contribution focuses on MS that consist of mechanisms that are driven by a servo-motor. In many cases, the energy-efficiency of the MS is crucial for the profitability of production machines. Often, the servo-motor has to apply a considerable part of the driving power to change the level of kinetic and potential energy in the system. When a mechanism is driven in its so-called Eigenmotion, no energy-input for changing the energy-level has to be applied. The energy-level of the system stays constant during the complete motion. In this contribution, the basic principles of energy-efficient mechanisms with a constant level of energy during its operation are discussed. A new method for the synthesis of such mechanisms is presented. The application of this method is shown by means of an example.

  • Robotic bat mechanism design
    • Authors: De-Ming Kong, Li-Biao Zhang, Jing-Shan Zhao, Sudeep Kumar Singh
      Pages: 418 - 430
      Abstract: This paper proposes a bat robot mechanism and investigates the kinematics of flying process. After observing the flight of bats for a long period of time and analysing its flying kinematics, a bionic robot was synthesised based on the bat structure to realise the deploying and flapping movements of the double membranous wings. With screw theory, the primary motion of the membranous wings was checked and six actuators were selected for controlling the flapping flight of the bat robot collaboratively. The structure is optimised by a bench test. A method is presented to measure the force output of the bat robot.
