Mechanical design can be intimidating, especially for someone new to the discipline because of the complexity and the limited number of resources available. The overarching goal of this project is to help mechanically curious individuals by creating an open-source 3D printed clock with detailed information and explanations for how the systems work and are designed. This increase in available knowledge will allow people to educate themselves by following or recreating the design process and, perhaps, inspire others to continue the learning process and study STEM.

Toy hacks modify commercially available toys to be more easily used by people with motor disabilities, and donate them to schools, families, or toy libraries. Switch-adapting a toy adds an audio jack to allow an assistive technology (AT) switch to be plugged in. Switch-adapted toys help children develop essential skills through play. Hacking toys is helpful because toys that come with AT switches are often significantly more expensive than their unadapted counterparts. Toy hacks are also an opportunity to teach and practice engineering skills such as soldering and technical problem solving. Many resources are available online to assist makers with hosting toy hacks, but most of them lack information on holding the event. To fill this gap, the authors created a toy hack guide website, drawing from experience hosting two toy hacks. It walks users through steps like choosing the size of the event, the materials that need to be purchased, and connects them to other existing resources. In the future, it will be used to help people host more successful toy hacks.

Due to the vast increase in processing power and energy usage in computing, a need for greater heat dissipation is prevalent. With numerous applications demanding cheaper and more efficient options for thermal management, new technology must be employed. Through the use of additive manufacturing, designs and structures can be created that were not physically possible before without extensive costs. The goal is to design a system that utilizes capillary action, which is the ability for liquids to flow through narrow spaces unassisted. The level of detail required may be achieved with direct metal laser sintering (DMLS) and stereolithography (SLA) 3D printing.

Balancing Control and Model Validation of Self-Stabilizing Motorcycle

Description
Bicycles and motorcycles offer maneuverability, energy efficiency and acceleration that four wheeled vehicles cannot offer given similar budget for. Two wheeled vehicles have drastically different dynamics from four wheeled vehicles due to their instability and gyroscopic effect from their wheels.

Bicycles and motorcycles offer maneuverability, energy efficiency and acceleration that four wheeled vehicles cannot offer given similar budget for. Two wheeled vehicles have drastically different dynamics from four wheeled vehicles due to their instability and gyroscopic effect from their wheels.

This thesis focuses on self-stabilization of a motorcycle using an active control momentum gyroscope (CMG) and validation of this multi-degree-of-freedom system’s mathematical model. Physical platform was created to mimic the simulation as accurately as possible and all components used were justified. This process involves derivation of a 3 Degree-of-Freedom (DOF) system’s forward kinematics and its Jacobian matrix, simulation analysis of different controller algorithms, setting the system and subsystem specifications, and real system experimentation and data analysis.

A Jacobian matrix was used to calculate accurately decomposed resultant angular velocities which are used to create the dynamics model of the system torque using the Euler-Lagrange method. This produces a nonlinear second order differential equation that is modeled using MATLAB/Simulink. PID, and cascaded feedback loop are tested in this Simulink model. Cascaded feedback loop shows most promises in the simulation analysis. Therefore, system specifications are calculated according to the data produced by this controller method. The model validation is executed using the Vicon motion capture system which captured the roll angle of the motorcycle. This work contributes to creating a set of procedures for creating a validated dynamic model for a CMG stabilized motorcycle which can be used to create variants of other self-stabilizing motorcycle system.
