A Novel Harmonic Drive With Pure Involute Tooth Gear Pair
(The American Society of Mechanical Engineers (ASME), 2004)Consider commercially available “harmonic drives” or “strain wave gearings” (all patented designs). The tooth profiles of the mating pairs of teeth of the noncircular (pitch curve) flex gear and ... -
Editorial
(The American Society of Mechanical Engineers (ASME), 2004)Included in this issue is a guest editorial by Professor John Uicker, who provides a personal perspective on the memory of leaders in mechanical design research. This November issue concludes ... -
Editorial
(The American Society of Mechanical Engineers (ASME), 2004)The review process for papers submitted to the Journal of Mechanical Design is now averaging less than six months and the publication backlog is three of its six yearly issues. This means ... -
Mobility Analysis of a Novel 3-5R Parallel Mechanism Family
(The American Society of Mechanical Engineers (ASME), 2004)Mobility analysis of a novel 3-5R parallel mechanism family whose limb consists of a 2R and a 3R parallel subchain is performed by the aid of screw theory. A mobility criterion applicable ... -
Kinematics Synthesis of Linkage Mechanisms With Cam Integrated Joints for Controlled Harmonic Content of the Output Motion
(The American Society of Mechanical Engineers (ASME), 2004)A new method is presented for the modification of the output motion of linkage mechanisms with closed-loop chains using cams positioned at one or more of its joints. As an example and to ... -
Optimal Motion Generation for Groups of Robots: A Geometric Approach
(The American Society of Mechanical Engineers (ASME), 2004)In this paper we generate optimal smooth trajectories for a set of fully-actuated mobile robots. Given two end configurations, by tuning one parameter, the user can choose an interpolating ... -
Two Basic Features of Instantaneous Conjugate Motion and Their Importance in Facilitating Motion Analysis
(The American Society of Mechanical Engineers (ASME), 2004)Two basic features of instantaneous conjugate motion, which distinguishes it from instantaneous free body motion, are pointed out. Their influences on the geometrical constraints requisite for ... -
Synthesis of a Five-Bar Mechanism of Variable Topology Type With Transmission Angle Control
(The American Society of Mechanical Engineers (ASME), 2004)A method to synthesize a planar five-bar mechanism of variable topology type with transmission angle control is suggested. The method is useful to reduce the solution space and thus the number ... -
Locally Linearized Dynamic Analysis of Parallel Manipulators and Application of Input Shaping to Reduce Vibrations
(The American Society of Mechanical Engineers (ASME), 2004)Input Shaping is a technique that seeks to reduce residual vibrations through modification of the reference command given to a system. Namely the reference command is convolved with a suitable ... -
Mobility Analysis of a Class of RPSPR Kinematic Chains
(The American Society of Mechanical Engineers (ASME), 2004)This paper presents mobility analysis and type identification of a class of RPSPR kinematic chains with zero twist on any one of the links carrying a revolute and prismatic pairs. Conditions ... -
On the Determination of Basic Dimensions of a Cam With a Translating Roller-Follower
(The American Society of Mechanical Engineers (ASME), 2004)The problem of determination of basic dimensions from the point of view of follower jamming of a cam with translating roller-follower is addressed. Departing from the common practice of using ... -
Type Synthesis of 3-DOF Translational Parallel Manipulators Based on Screw Theory
(The American Society of Mechanical Engineers (ASME), 2004)A method is proposed for the type synthesis of 3-DOF (degree-of-freedom) translational parallel manipulators (TPMs) based on screw theory. The wrench systems of a translational parallel kinematic ... -
Displacement Analysis of Spherical Mechanisms Having Three or Fewer Loops
(The American Society of Mechanical Engineers (ASME), 2004)Spherical linkages, having rotational joints whose axes coincide in a common center point, are sometimes used in multi-degree-of-freedom robot manipulators and in one-degree-of-freedom mechanisms. ... -
Type Synthesis of 3-DOF Spherical Parallel Manipulators Based on Screw Theory1
(The American Society of Mechanical Engineers (ASME), 2004)A spherical parallel manipulator (SPM) refers to a 3-DOF (degree-of-freedom) parallel manipulator generating 3-DOF spherical motion. A method is proposed for the type synthesis of SPMs based on ... -
Kinematic Analysis and Design of Kinematically Redundant Parallel Mechanisms
