Symmetry Method for Limit Cycle Walking of Legged Robots.
(2016)
Dynamic steady-state walking or running gaits for legged robots correspond to periodic orbits in the dynamic model. The common method for obtaining such periodic orbits is conducting a numerical search for fixed points of ...
A Multiple Height Transfer Interferometric Technique and Its Applications
(2012)
Absolute distance interferometric metrology is one of the most useful techniques for dimensional measurements. Without movement, measurements can be made without ambiguity, by using either one or several synthetic wavelengths. ...
Packaging Technologies for Millimeter Scale Microsystems in Harsh Environment Applications
(2016)
Microsystems capable of sensing temperature, pressure and other parameters are needed for many applications, for example, gathering information in downhole environments for oil and gas exploration. Certain target locations ...
Hybrid Electric Powertrain Design and Control with Planetary Gear Sets for Performance and Fuel Economy
(2018)
Planetary gear sets (PGs) play a key role in hybrid electric vehicle (HEV) design by enabling a variety of unique architectures using a limited number of powertrain components. Leveraging the capability of this mechanical ...
Design and Analysis of Extremely Low-Noise MEMS Gyroscopes for Navigation
(2018)
Inertial measurement sensors that include three gyroscopes and three accelerometers are key elements of inertial navigation systems. Miniaturization of these sensors is desirable to achieve low manufacturing cost, high ...
Input and State Estimation for Discrete-Time Linear Systems with Application to Target Tracking and Fault Detection
(2018)
This dissertation first presents a deterministic treatment of discrete-time input reconstruction and state estimation without assuming the existence of a full-rank Markov parameter. Algorithms based on the generalized ...
Origami and Kirigami Design Principles for Optical Tracking, Energy Harvesting, and Other Applications
(2017)
Origami and kirigami (the folding and cutting of paper, respectively, to achieve a desired shape) have been used in engineering to develop airbags, optical components, deployable spaceborne solar arrays, reprogrammable ...
Microsystem-Compatible Heterogeneous Micro-Hydrophone for Use at High Static Pressures
(2019)
Underwater acoustic sensing is important for multiple applications, including seismic sensing for the oil and gas industry, SONAR at extended ocean depth, localization of underwater vehicles, implementation in autonomous ...
Control of Micro-Hybrid Boosting
(2019)
Powertrain hybridization has been shown to greatly improve vehicle fuel economy, with significant additional component costs. A novel type of low voltage hybrid device, called a power split supercharger (PSS), has the ...
Autonomous Scene Understanding, Motion Planning, and Task Execution for Geometrically Adaptive Robotized Construction Work
(2019)
The construction industry suffers from such problems as high cost, poor quality, prolonged duration, and substandard safety. Robots have the potential to help alleviate such problems by becoming construction co-workers, ...
