Mechanical Design And Optimization Of An Interactive Animatronic Bald Eagle, Eric Burns 2016 Georgia Southern University

Mechanical Design And Optimization Of An Interactive Animatronic Bald Eagle, Eric Burns

Phi Kappa Phi Research Symposium

Animatronics is a specialized sub-category of mechatronics, a fusion of mechanical and electrical engineering. The field has grown from small, individual projects into a major industry. As animatronics progress, mechanical engineers are pushed to design internal structures which occupy ever-decreasing spaces and to ensure designs can undergo maintenance and modifications smoothly. This research investigates methods of reducing space required for mechanisms and several other beneficial methods of development as well as varying satisfactions for audiences when exposed to actor-controlled systems rather than pre-scripted functions. The mechanical systems are designed using CAD software available at Georgia Southern. On-campus, resources are used ...

Laser Assisted Manufacturing: A Comparison Of Mechanical Properties Between Lam And Conventional Manufacturing Techniques, William Blakeslee, Neil S. Bailey, Kyung-Min Hong, Shunyu Liu, Yung C. Shin

The Summer Undergraduate Research Fellowship (SURF) Symposium

Laser assisted manufacturing methods, such as direct metal deposition (DMD) and laser beam welding (LBW), are promising methods because of their higher precision and greater productivity when compared to traditional manufacturing methods. Because these methods are relatively new, the mechanical properties of samples produced by laser assisted manufacturing are not well understood. In this study the mechanical properties of samples produced by laser assisted manufacturing methods are analyzed and compared with data obtained from traditional manufacturing methods. The DMD process used Fe-TiC and Ti-TiC metal matrix composites, while LBW used AISI 304 stainless steel. The results vary widely with the ...

The Summer Undergraduate Research Fellowship (SURF) Symposium

Energetic materials are currently manufactured using methods such as casting, which can only produce certain geometries. Additive manufacturing enables more flexible fabrication and the potential for improved material consistency. Additive manufacturing has transformed many industries, but has only recently been applied to the manufacturing of energetic materials. This paper describes the development of two processes to apply additive manufacturing methods to energetic materials. Method one applies a fused deposition modelling approach (FDM). 5 µm aluminum powder and PVDF were mixed and made into filaments using a Filabot Original filament extruder. Energetic filaments were created composed of 90:10, 80:20 ...

Laser-Assisted Microchanneling On Pmma Substrate Utilizing Two-Pass Fabrication Method, Sijie Zhang, Yung C. Shin

The Summer Undergraduate Research Fellowship (SURF) Symposium

Microchannel is widely used in microfluidic devices for mixing, chemical reaction, detection, particle separation and etc. CO2 laser-based microchanneling of PMMA as a low cost, rapid, noncontact fabrication method has attracted the attention of industry. However, the typical V-shape grooves fabricated by CO2 laser microchanneling have limitations since the V-shape grooves will affect the flow behavior and heat transfer of the fluid, which are important to the performance of microfluidic devices. A two-pass fabrication method is proposed and investigated in this paper to improve the quality of the PMMA microchannel fabricated by CO2 laser. It was found ...

Industrial and Manufacturing Engineering

The purpose of this project is to design a new off-road bumper that is improved from the stock form of a 1996-2002 Toyota 4Runner and a 1996-2004 Toyota Tacoma. The current state of the component is too weak to endure to off-road endeavors, and a kit bumper market is virtually untapped for these vehicles. The objectives of this project were met by redesigning the stock front bumper, conducting a finite element analysis on the model to test for strength, prototyping the bumper with CNC cut cardboard, and conducting a full cost analysis including the costs for waterjet and laser cutting ...


Revealing Student Misconceptions And Instructor Blind Spots With Muddiest Point Formative Feedback, Cindy Waters, Stephen Krause, Janet Callahan, Barry Dupen, Mary Vollaro, Peggy Weeks 2016 North Carolina A & T State University

Revealing Student Misconceptions And Instructor Blind Spots With Muddiest Point Formative Feedback, Cindy Waters, Stephen Krause, Janet Callahan, Barry Dupen, Mary Vollaro, Peggy Weeks

Manufacturing and Construction Engineering Technology Faculty Presentations

Of interest to all engineering disciplines, well-designed formative feedback has the potential to enhance both instructor teaching and student learning. Delivering fundamental courses year after year can ultimately lead faculty to use stale notes or slides from past years. This approach may save time but does not meet the shifting needs of our students who have high expectations from their instructors. One simple method to improve teaching is to employ muddiest point reflections. Muddiest point reflections involve simply asking students to anonymously reflect on what was "muddy", i.e. confusing, during class and to rank their level of confusion which ...

Inclusive Lectern, Trent Canales, Sean Day, Dylan Sigley, Stephen Sippel

Mechanical Engineering

A lectern is an essential piece of equipment for almost all speeches and presentations. They come in many forms and range in degree of professionalism depending on the occasion. Lecterns not only hold a presenter’s notes, a microphone, or other presentation aids, they provide a structure for a presenter that can bolster their confidence during a presentation. As such, it is important that all presenters have a lectern available to them. Unfortunately this is not always the case due to lectern accessibility limitations. This problem inspired the Cal Poly Disability Resource Center to request a lectern that satisfies the ...
