Nasa Student Launch Payload Deployment, Kallysta Ray

All Undergraduate Projects

For the NASA Student Launch Competition, a deployment system was created to deploy the payload of the rocket. To accomplish this the deployment system was designed, analyzed, manufactured, and tested to meet the requirements from the NASA Competition. The requirements included deployment of the payload as well as staying within 4 pounds. The project requirements were researched and each of the proposed components had analyses completed. The analyses included weight calculations, stress, and deflection analyses using statics, mechanics of materials, and dynamics. There were many discussions throughout the project between the teammates to ensure all components of the payload and …

Radio-Controlled Baja Car, Jaxx Brown

All Undergraduate Projects

The Central Washington University RC Baja competition tests students’ skills in engineering in a matter of ability to design, construct and test an RC car. The objective of this senior project is to manufacture efficient suspension and steering systems for an RC vehicle and compete at the end of the school year against other students’ vehicles. Two races will be conducted during the competition, the RC vehicle will compete in a slalom-and-sprint and a Baja. Using more than one manufacturing method and material was expected of students to create the steering and suspension systems. Through CAD software and 3D printers …

Prosthetic Hand: Structure, Riley Smith, Riley Smith

All Undergraduate Projects

The objective of this project was to design the structure of a prosthetic hand that has articulating fingers and thumb in order to grip various objects. A design was developed that can add to the available options of prosthetics on the market.

In order to create a base hand for the project, the hand was modeled off of rough human hand dimensions. Analyses determined the feasible size of components. Once a base size was found the movement system in both grip and return form were developed and refined. With the parts being modeled in Solidworks and 3D printed, iterations of …

Pneumatic Gripper for Cast Products

By: Jacob VanBlaricom

Mentors: Craig Johnson (craig.johnson@cwu.edu), Kurt Gray (kgray06@northstarcasteel.com ),

Ted Bramble (ted.bramble@cwu.edu) , Travis Lamberte (travis@northstarcasteel.com )

The Team was tasked by NorthStar Casteel to create a device that would allow for easy mobility and manipulation of unfinished cast products. The device is needed to increase manufacturing time and decrease worker strain. In order to do this the team designed a custom gripper to match the castings produced at this facility. The gripper was powered by a pneumatic system due to the speed and reliability in this …

Asme Mini-Baja Rc Car (Steering And Suspension Systems), Michael E. Cox

All Undergraduate Projects

The issue that this project is concerned with is how to design and build a drivetrain, steering and suspension systems for an RC car. The systems must be simple and functional. Furthermore, these systems will be designed to fit on a small chassis and not interfere with each other. They also need to be strong and durable enough to propel the car forward and maneuver through various obstacles and be built in a way that is easy to take apart and repair quickly. These design problems were approached using basic mechanical design concepts such as gear kinematics, spur and bevel …
