Developing And Testing An Anguilliform Robot Swimming With Theoretically High Hydrodynamic Efficiency, John B. Potts Iii
Developing And Testing An Anguilliform Robot Swimming With Theoretically High Hydrodynamic Efficiency, John B. Potts Iii
University of New Orleans Theses and Dissertations
An anguilliform swimming robot replicating an idealized motion is a complex marine vehicle necessitating both a theoretical and experimental analysis to completely understand its propulsion characteristics. The ideal anguilliform motion within is theorized to produce ``wakeless'' swimming (Vorus, 2011), a reactive swimming technique that produces thrust by accelerations of the added mass in the vicinity of the body. The net circulation for the unsteady motion is theorized to be eliminated.
The robot was designed to replicate the desired, theoretical motion by applying control theory methods. Independent joint control was used due to hardware limitations. The fluid velocity vectors in the …

Design And Manufacture Of Mesoscale Robot-Actuated Surgical Instruments, Clayton L. Grames
Theses and Dissertations
Minimally Invasive Surgery (MIS) is a growing field including both laparoscopic androbotic operations. Surgeons and engineers are making continual efforts to reduce the negative effects of procedures on patients. Reducing the size of the surgical instruments is one effective method pursued in this effort. When the instruments approach 3 mm in diameter, they reach a threshold where the entry incisions can be small enough that no scar is left on the patient. Laparoscopic instruments on this scale exist but typically lack wrist articulation and only have 1 degree of freedom (DoF). Alternatively, robotic surgical instruments can achieve high levels of …

Basketballbot: Education Level Development Of A Fuzzy Controller For A Linear Motor Under Saturation Limits, David L. Mcpherson
Basketballbot: Education Level Development Of A Fuzzy Controller For A Linear Motor Under Saturation Limits, David L. Mcpherson
Honors Theses
Fuzzy logic seeks to express human modes of reasoning and decision making in a mathematical form. This is evident in its terminology such as “linguistic variables” defined over a “universe of discourse”. By taking human expressions such as “very high” or “pretty cold” and defining them in a mathematical context, expert operator knowledge can be transferred from verbal descriptions into automated control algorithms regardless of the operator’s familiarity with control systems. Because fuzzy logic is designed to be easily comparable with human thought, it makes an excellent first exposure to control systems concepts to high school and undergraduate students. Additionally, …

Characterization Of A Robotic Manipulator For Dynamic Wind Tunnel Applications, James C. Lancaster
Characterization Of A Robotic Manipulator For Dynamic Wind Tunnel Applications, James C. Lancaster
Theses and Dissertations
The newly acquired 6-DOF Motion Test Apparatus (MTA) was installed to perform dynamic wind tunnel testing in the AFIT Low Speed Wind Tunnel. Several complex motions revealed that the overall performance of the test rig needed improvement especially during small motions. The motions exposed that further enhancements would need to be performed individually for each joint. This research effort focused on the improvement of the MTA wrist roll motor and controller using a pitch oscillation. The controller software was improved using position feedback because the MTA wrist roll motor and controller exhibited reduced signal bias and amplitude attenuation. The enhanced …
Optimal Design And Control Of A Lower-Limb Prosthesis With Energy Regeneration, Holly E. Warner
Optimal Design And Control Of A Lower-Limb Prosthesis With Energy Regeneration, Holly E. Warner
ETD Archive
The majority of amputations are of the lower limbs. This correlates to a particular need for lower-limb prostheses. Many common prosthesis designs are passive in nature, making them inefficient compared to the natural body. Recently as technology has progressed, interest in powered prostheses has expanded, seeking improved kinematics and kinetics for amputees. The current state of this art is described in this thesis, noting that most powered prosthesis designs do not consider integrating the knee and the ankle or energy exchange between these two joints. An energy regenerative, motorized prosthesis is proposed here to address this gap. After preliminary data …

Generalized Mapping And Object Removal, Duncan Campbell
Williams Honors College, Honors Research Projects
Simultaneous localization and mapping (SLAM) is a problem that has been explored for the past few decades. SLAM deals with the concept of a robot being introduced into an environment in which it has no prior knowledge. Then, through the use of sensors, the robot is able to map its environment while simultaneously determining its position within the given area. While there has been extensive research into the development of methods by which this problem can be solved, not much has been done on what to do with the resulting maps once they are produced. The research conducted deals with …
