Development Of A Compliant Gripper Driven By 3 Dof Soft Robot, Derek M. Price Ii, Ricardo Ramirez, Pt Angel Tran

Symposium of Student Scholars

Industrial robots are moving toward automation, which makes it increasingly necessary to replace the functions traditionally performed by humans with robotics. Pick and place operation is a prime example of such automation. Robots that pick up and place objects mimic the human action of picking an object up and placing it in a targeted location. It has led to the development of robotic end-effectors that have a human-like feel. Grippers can be articulated in various ways depending on their application area and well-defined desired tasks. As compliant and soft links deflect more under the same load than their rigid body …

Novel Thermal Coating For High-Speed Airplanes, Abinash Satapathy, Lakshay Battu, Liam Watson, Nazanin Rajabi

Symposium of Student Scholars

In comparison to various other materials, Carbon Fiber, specifically Carbon Fiber Reinforced Polymers (CFRP), is pre-eminent amongst other materials for use on aeronautical systems. Due to its high specific strength (strength-to-weight ratio), CFRP is prominent for carrying heavy loads while maintaining a lightweight build. However, when influenced by heat resulting from air resistance, CFRP is known to undergo serious degradation that would significantly decrease the effectiveness of the polymers. To prevent this degradation and maintain the strength of the CFRP, thermal protective layers (TPLs) are designed to shield the CFRP from heat exposure. This research is focused on the examination …

Using Comprehensive Finite Element Analysis To Simulate A Special Connection In Post-Tensioned Concrete, Joshuah Leljedal

Symposium of Student Scholars

Finite element analysis (FEA) uses differential equations to determine a computer-based solution that explains interactive behaviors within models of complex structural and mechanical systems, subjected to various loading and environmental conditions. Those systems are partitioned into finite elements consisting of a linear mesh with nodes at each end point, and FEA determines relationships, such as force-displacement, between each of the finite elements. This apportioned model allows systems to be evaluated under multiple loading scenarios. Computer-based FEA offers significant benefits that reduce cost and the time required to perform alternative analysis for complex structural systems. In this research project, a comprehensive …
