Gasification of biomass for energy production has the potential to be a cost effective and environmentally sustainable technology. Small scale, 20-250 kWth, downdraft gasifiers have the ability to provide power from low cost regionally...
Autonomous ground vehicles (AGVs) are expected to be used extensively in unstructured, outdoor, undulating environments for tasks such as search and rescue, homeland security, fire fighting, reconnaissance, and surveillance. These tasks...
Skid-steered robots are commonly used in outdoor applications due to their mechanical simplicity, high maneuverability, and robustness. The maneuverability of these robots allows them to perform turning maneuvers ranging from point turns...
When driving on off road terrains, experienced drivers utilize driving rules that have been developed through experience to handle difficult driving conditions such as traversing soft terrains, descending steep hills, and traversing...
Graphene based nanocomposites became the most popular research interest for researchers in the manufacturing of sensor and actuator devices because of their novel electrical and mechanical properties and very good piezoresistive behavior...
Autonomous ground vehicles (AGVs) are commonly used for search and rescue, military and forestry purposes. To safely and efficiently perform missions in these environments the AGV must adapt its driving and control strategies based on...
A negative sequence analysis coupled with fuzzy logic and neural network based approaches are applied to stator winding short circuit fault detection in a permanent magnet synchronous motors (PMSM). A fuzzy logic based approach is...
A new robotic leg design is presented that utilizes dielectric elastomers (3M VHB 4910) to rapidly control stiffness changes for enhanced mobility and agility of a field demonstrated hexapod robot. It has been shown that stiffness...
An increasing number of applications require the use of high temperature superconductors (HTS) such as (RE=Rare Earth) Ba2Cu3O7-x (REBCO) coated conductors [1]. HTS conductors show particularly great potential for high field magnets...
To increase autonomous ground vehicle (AGV) safety and efficiency on outdoor terrains the control system should have settings for individual terrains. A first step in such a terrain-dependent control system is classification of the...
A piezohydraulic active flow control actuator is developed using a 400 µm diameter micro jet that is capable of pulsing flow over a broad frequency range. The design of the piezohydraulic microjet is presented together with experimental...
Rapid heat deposition is a natural consequence of an insulating vacuum jacket failure around a He II-cooled system. This loss of vacuum is often referred to as the worst-case scenario, as it seriously endangers its surroundings and the...
Smart materials are materials that exhibit field-coupled material behavior in response to external stimuli. One example is photomechanical materials that are able convert light energy into mechanical work. Light is a unique form of...
Wheeled vehicles typically suffer from kinematic wheel slip when moving over an uneven terrain. This wheel slip can lead to decreased localization ability, higher sensory and computational burdens, uncontrolled motion, and decreased...
