RISCompression Molding and Nickel Molds for Directional Gecko-Inspired Adhesives
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the fabrication of directional gecko-inspired adhesives, a new capability made possible by the availability of metal molds is hot compression molding. This molding process allows the use of elastomers with much higher ...
PEDOT:PSS Coating Improves Gecko-Inspired Adhesive Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We report a surface treatment for an elastomeric dry adhesive that improves adhesion, especially on surfaces with microscopic roughness. The process involves coating wedge-shaped polydimethylsiloxane (PDMS) features of the ...
A Passive Parallel Master–Slave Mechanism for Magnetic Resonance Imaging Guided Interventions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A passive, parallel master–slave mechanism is presented for magnetic resonance imaging (MRI)guided interventions in the pelvis. The mechanism allows a physician to stand outside the MRI scanner while manipulating a needle ...
The Role of Tissue Slip Feedback in Robot-Assisted Surgery
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Slip, or accidental loss, of grasped biological tissue can have negative consequences in all types of surgery (open, laparoscopic, robot-assisted). This work focuses on slip in robot-assisted surgery (RAS) with the goal ...

Creating Metal Molds for Directional Gecko-Inspired Adhesives
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We describe a process for creating durable metal molds for the fabrication of directional, gecko-inspired dry adhesives. The adhesives require microscopic inclined features with a challenging combination of tapered geometry, ...
Surface and Shape Deposition Manufacturing for the Fabrication of a Curved Surface Gripper
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Biological systems such as the gecko are complex, involving a wide variety of materials and length scales. Bioinspired robotic systems seek to emulate this complexity, leading to manufacturing challenges. A new design for ...
Microwedge Machining for the Manufacture of Directional Dry Adhesives
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Directional dry adhesives are inspired by animals such as geckos and are a particularly useful technology for climbing applications. Previously, they have generally been manufactured using photolithographic processes. This ...
Cutting to the Point: Directly Machined Metal Molds for Directional Gecko-Inspired Adhesives
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fabrication techniques for gecko-inspired adhesives generally target mold durability, adhesive performance, and process efficiency and simplicity. With these goals in mind, we present a micromachining process for creating ...
Aggressive Flight With Quadrotors for Perching on Inclined Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Microaerial vehicles (MAVs) face limited flight times, which adversely impacts their efficacy for scenarios such as first response and disaster recovery, where it might be useful to deploy persistent radio relays and ...
