Design upgrade for 2.670 compressed air robot
(Massachusetts Institute of Technology, 2009)
2.670 is an introductory Mechanical Engineering course that introduces students to the fundamentals of machine tool and computer tool use through the fabrication of a robot that is powered by compressed air. The compressed ...
Wireless bicycle assist : structural analysis of outer casing
(Massachusetts Institute of Technology, 2009)
Although cost effective and environmentally friendly, bicycles are impractical for many users due to the required strength and physical exertion. The GreenWheel is a set of mechanical and electronic devices that provide ...
Design and control of a planar two-link manipulator for educational use
(Massachusetts Institute of Technology, 2009)
This paper proposes a new robotic planar two-link manipulator design for educational use. Planar two-link manipulators are among the most accessible two-degree-of-freedom robots for students because they function like human ...
Systematic characterization and calibration of a three dimensional ultrasonic positioning system for use in mobile robots
(Massachusetts Institute of Technology, 2009)
This thesis examined the characteristics of the Hexamite Hx11 ultrasonic sensor for the purpose of three dimensional positioning for mobile robots with multi-plane motions. The sensor system was studied and an experiment ...
Lifecycle of viral YouTube videos
(Massachusetts Institute of Technology, 2014)
YouTube was founded in 2005 as a video-sharing website. Today, it's a powerhouse social media platform where users can upload, view, comment, and share content. For many, it's the first site visited when looking for songs, ...
Development of a novel chip-based platform for long-term neuronal culture, stimulation, and imaging
(Massachusetts Institute of Technology, 2009)
The flame plasma treatment studied in this thesis was able to oxidize the surface of Polydimethylsiloxane (PDMS) in a fraction of a second. It was found to be a much faster way to modify PDMS surface wettability than the ...
Development of folding three-wheeled wheelchair frame for the Developing World
(Massachusetts Institute of Technology, 2009)
Currently, wheelchairs in developing countries are supplied both through donations from NGOs and local wheelchair workshops in these countries. A popular type of wheelchair manufactured by these workshops is a three-wheeled ...
All-optical method of nanoscale magnetometry for ensembles of nitrogen-vacancy defects in diamond
(Massachusetts Institute of Technology, 2015)
The Nitrogen-Vacancy (NV) defect in diamond has shown considerable promise in the field of small scale magnetometry due to its high localization and retention of favorable optical properties at ambient conditions. Current ...
Mold design, fabrication and tensile testing of EMBed-812, a tissue embedding epoxy resin
(Massachusetts Institute of Technology, 2014)
Serial sectioning is a process whereby fixed tissue is embedded in a polymer to preserve structure and is then sliced into very thin sections as small as 25nm. Currently, there is a lack of understanding of this embedding ...
Fabrication and characterization of perpendicular magnetic anisotropy thin-film CoCrPt grown on a Ti underlayer
(Massachusetts Institute of Technology, 2015)
CoCrPt has potential applications as a memory storage technology because of its perpendicular magnetic anisotropy (PMA) characteristics. An underlayer can be used to ensure the out-of-plane magnetization required for PMA ...
