On learning from videos/
(Massachusetts Institute of Technology, 2018)
The robot phone disassembly task is difficult in many ways: It has requirements on high precision, high speed, and should be general to all types of cell phones. Previous works on robot learning from demonstration are ...
Stability-constrained design for low voltage DC microgrids
(Massachusetts Institute of Technology, 2018)
Microgrids are a promising solution to reducing the energy access gap. However, microgrids are inherently fragile systems as they are not globally stable. This thesis considers two voltage instabilities that can arise in ...
A study of node-based finite elements for the solution of the time-harmonic Maxwell equations
(Massachusetts Institute of Technology, 2017)
Classical node-based finite elements are well-known to cause difficulties in the solution of the Maxwell equations. These difficulties are discussed and investigated by means of numerical examples in this thesis. Time-harmonic ...
Tactile measurement with a GelSight sensor
(Massachusetts Institute of Technology, 2014)
This thesis introduces a method of measuring contact force with GelSight. GelSight is an optical-based tactile sensor that uses a piece of coated elastomer as the contact medium. A camera records the distortion of the ...
Time-optimal multi-waypoint mission planning in dynamic flow fields
(Massachusetts Institute of Technology, 2018)
This thesis demonstrates the use of exact equations to predict time-optimal mission plans for a marine vehicle that visits a number of locations in a given dynamic ocean current field. The missions demonstrated begin and ...
M-Blocks : three dimensional modular self-reconfigurable robots
(Massachusetts Institute of Technology, 2018)
This thesis details the development of the 3D M-Blocks modular robot system. Modular self-reconfigurable robots (MSRR) are robotic systems which contain many modules that can form and break connections with other modules, ...
Deployment of a passive acoustic detection system for reactive collision avoidance in autonomous underwater vehicles
(Massachusetts Institute of Technology, 2017)
The use of autonomous vehicles in air, land and water has grown in recent years, with increased attention given to heavily transited areas. For the case of autonomous underwater vehicles, these regions of interest include ...
Ab initio study of electron transport in lead telluride
(Massachusetts Institute of Technology, 2018)
Last few years have witnessed significant enhancement of thermoelectric figure of merit of lead telluride (PbTe) via nanostructures. Despite the experimental progress, current understanding of the electron transport in ...
Study of the factors that influence the lubrication of the three-piece oil control ring
(Massachusetts Institute of Technology, 2017)
The oil control ring (OCR) is arguably the most important component of the piston ring pack system in internal combustion engines. The OCR regulates the oil supply to the top two rings and therefore is critical to both ...
The consequences of the enterprise not engaging in the manufacturing system design
(Massachusetts Institute of Technology, 2002)
