Design and fabrication of granular materials for surface acoustic waves
(Massachusetts Institute of Technology, 2015)
Granular materials with structural discreteness and periodicity can lead to novel propagation behaviors of mechanical waves. Acoustic studies of granular media typically involve macroscopic particles whereas contact-based ...
Design of an Autonomous Underwater Vehicle (AUV) charging system for underway, underwater recharging
(Massachusetts Institute of Technology, 2014)
Modern robotics have enabled the rapid proliferation of Autonomous Underwater Vehicles (AUVs) throughout the marine environment. As autonomy algorithms increase in robustness, complexity, and reliability, so too does the ...
Design of an instrumented multifunctional foot for application to a heavy duty mobile robot manufacturing system
(Massachusetts Institute of Technology, 2008)
The design of a multifunctional foot for application to a mobile robotic system for heavy duty manufacturing is presented. The requirements for a target manufacturing task are presented and translated into requirements for ...
Analysis of system wide distortion in an integrated power system utilizing a high voltage DC bus and silicon carbide power devices
(Massachusetts Institute of Technology, 2007)
This research investigates the distortion on the electrical distribution system for a high voltage DC Integrated Power System (IPS). The analysis was concentrated on the power supplied to a propulsion motor driven by an ...
Particle displacement measurement using optical diffraction
(Massachusetts Institute of Technology, 2002)
DC to DC power conversion module for the all-electric ship
(Massachusetts Institute of Technology, 2011)
The MIT end to end electric ship model is being developed to study competing electric ship designs. This project produced a model of a Power Conversion Module (PCM)- 4, DC-to-DC converter which interfaces with the MIT ...
Optimal control with structure constraints and its application to the design of passive mechanical systems
(Massachusetts Institute of Technology, 2002)
Structured control (static output feedback, reduced-order control, and decentralized feedback) is one of the most important open problems in control theory and practice. In this thesis, various techniques for synthesis of ...
An efficient drive, sensing, and actuation system using PZT stack actuator cells
(Massachusetts Institute of Technology, 2012)
The PZT cellular actuator developed in the MIT d'Arbeloff Laboratory utilizes small-strain, high-force PZT stack actuators in a mechanical flexure system to produce a larger-strain, lower-force actuator useful in robotic ...
Autonomous adaptation and collaboration of unmanned vehicles for tracking submerged contacts
(Massachusetts Institute of Technology, 2012)
Autonomous operations are vital to future naval operations. Unmanned systems, including autonomous underwater vehicles (AUVs) and autonomous surface vehicles (ASVs), are anticipated to play a key role for critical tasks ...
Shipboard condition based maintenance and integrated power system initiatives
(Massachusetts Institute of Technology, 2011)
With the U.S. Navy's continued focus on developing and implementing a robust integrated power system aboard future combatants, there has been an ever increasing effort to guarantee an electrical distribution system that ...
