RISDesign of an Underactuated, Flexure-Based Gripper, Actuated Through a Push–Pull Flexure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The design of grippers for the agro-industry is challenging. To be cost-effective, the picked object should be moved around fast requiring a firm grip on the fruit of different hardnesses, shapes, and sizes without causing ...
Microtube Laser Forming for Precision Component Alignment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A micro-actuator for precision alignment, using laser forming of a tube, is presented. Such an actuator can be used to align components after assembly. The positioning of an optical fiber with respect to a waveguide chip ...
Beams With a Varying Cross Section in the Generalized Strain Formulation for Flexure Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flexure joints are rapidly gaining ground in precision engineering because of their predictable behavior. However, their range of motion is limited due to a stress limitation and a loss of support stiffness in deformed ...
Kinematic Design Method for Rail-Guided Robotic Arms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For special purpose robotic arms, such as a rail mounted ballast-water tank inspection arm, specific needs require special designs. Currently, there is no method to efficiently design robotic arms that can handle not ...
CT Registration: Experimental Determination of Suited Fiducial Marker Material and Registration Errors
Publisher: The American Society of Mechanical Engineers (ASME)
Efficient Computation of Large Deformation of Spatial Flexure-Based Mechanisms in Design Optimizations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Design optimizations of flexure-based mechanisms take a lot of computation time, in particular when large deformations are involved. In an optimization procedure, statically deformed configurations of many designs have to ...

Exact Constraint Design of a Two Degree of Freedom Flexure Based Mechanism1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We present the exact constraint design of a two degrees of freedom crossflexurebased stage that combines a large workspace to footprint ratio with high vibration mode frequencies. To maximize unwanted vibration mode ...
Modeling of a Flexible Instrument to Study its Sliding Behavior Inside a Curved Endoscope
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flexible instruments are increasingly used to carry out surgical procedures. The instrument tip is remotely controlled by the surgeon. The flexibility of the instrument and the friction inside the curved endoscope jeopardize ...
Improved Force Transmission of a Flexible Surgical Instrument by Combining Input Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The force transmission of a flexible instrument through an endoscope is considerably deteriorated due to friction between the contacting surfaces. Friction force along the axial direction can be reduced by combining the ...
