Research Articles Symbolic Computation Techniques for Multibody Model Development and Code Generation Proceedings of MULTIBODY DYNAMICS 2011, ECCOMAS Thematic Conference This paper presents some of the benefits of a general purpose symbolic computation environment when constructing and generating simulation code for multibody, multidomain systems. Specifically, it considers how tools provided by these environments can be harnessed to generate highly efficient simulation code. Role of Automated Symbolic Generation of Equations of Motion to Enhance Robotics Education Proceedings of the ASME 2010 International Design Engineering Technical Conferences & Computers and Information in Engineering Conference In this research paper, the authors (Hrishi Shah, Sumit Tripathi, Leng-Feng Lee, and Venkat Krovi) examine how symbolic modeling tools such as MapleSim can be used to enhance students' understanding of concepts in mechanisms/robotics courses. Kinematic-, Static- and Workspace Analysis of a 6-P-U-S Parallel Manipulator Proceedings of the ASME 2010 International Design Engineering Technical Conferences & Computers and Information in Engineering Conference In this research, Dr. Krovi and his research team analyzed a general 6 degree of freedom 6-Prismatic-Universal-Spherical (6-P-U-S) type manipulator. They used Maple and MapleSim to automatically generate the governing equations, and conducted a kinematic analysis of those equations with Maple. Using Symbolic Technology to Derive Inverse Kinematic Solutions for Actuator Control Development Proceedings of MathMod Vienna 2012, the Vienna Conference on Mathematical Modelling In this paper, we will describe how to obtain a symbolic solution to the inverse kinematics problem for two real problems using tools available in MapleSim.

Kinematics Analysis of In-Parallel 5 DOF Haptic Device 2010 IEEE/ASME International Conference on Advanced Intelligent Mechatronics Montréal, Canada, July 6-9, 2011 We build on the rich theoretical background of constrained articulated mechanical systems to provide a systematic framework for formulation of system-level kinematic performance from individual-arm characteristics. Analysis and Design Optimization of Inparallel Haptic Devices Leng-Feng Lee Department of Mechanical and Aerospace Engineering State University of New York at Buffalo Our focus will be on the development of advanced HUIs for providing the users with sophisticated tactile or force feedback during interaction with virtual environments with innovative features including active and passive manipulation assists. Closing The Design Loop In Freshman Engineering Proceedings of the ASEE 2011 Annual Conference & Exposition Thomas E. Doyle and Spencer Smith (McMaster University), and Adrian Ieta (State University of New York, Oswego) present a model for teaching freshmen design that incorporates documenting the idea, formalizing the design, and model simulation for verification and improvement. This last element is frequently absent from freshman design course, but by using MapleSim, they are able to close the design loop, making the material more engaging for students of all disciplines and allowing the instructor to go much further in the design discussion. Using MapleSim to model a six-strut kinematic mount for aligning optical components © 2011 COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE). This paper examines the behaviour of a six-strut kinematic mount using MapleSim to investigate and understand precisely how a mirror pole moves with its mount and quantify any cross-coupled motion that may occur during actuator adjustments. Symbolic Math-Based Battery Modeling for Electric Vehicle Simulation Proceedings of the ASME 2010 International Design Engineering Technical Conferences & Computers and Information in Engineering Conference We present results of a math-based model of a battery electric vehicle (BEV) designed in MapleSim. This model has the benefits of being described in a physically consistent way using acausal system components Mathematics-Based Modeling of a Series-Hybrid Electric Vehicle Proceedings of the 5th Asian Conference on Multibody Dynamics 2010 An approach to modeling a series-HEV based on a mean-value ICE, a chemistry-based Ni-MH battery pack, and a multibody dynamic vehicle is proposed. This is accomplished using MapleSim utilizing symbolic operations from a general purpose algebra software package to develop and optimize the system equations. The model contains a set of DAEs across multiple domains, namely mechanical, electrical, chemical, and hydraulic domains. The simulation results obtained are viable and show that the number of governing equations is reduced significantly, making real-time simulations and HIL applications promising.
