Steering Laws for Pursuit
… mathematicians and engineers. Guidance/steering laws are essential in robotic systems. In this thesis, we first review the results on steering laws for a specific pursuit process, motion camouflage with respect to infinity. This type of guidance law renders the baseline (line connecting …

Open wheel racecar steering
The steering system of a rear wheel drive open wheel racecar is the only directional control the driver possesses while driving. Steering linkages must be carefully designed to allow cars to navigate turns without exhausting the driver. Motorsports vehicles are designed to make tight turns while …

Law as a regulator: steering waste management by steering itself through its relationship with the environment
… system steers the waste management process by steering itself through its relationship with the environment, with steering mediated by organisations, such as households, courts, government departments, local authorities and businesses. Through an encounter between Luhmann’s theory and Cass …

Haptic Interface for Non-Visual Steering
… direction and how far to steer, as to facilitate steering without any visual feedback. Our interface may improve driving safety when a driver is temporarily blinded, for example, due to glare or fog. Three user studies were performed, the first study tries to understand driving using visual …

Steering Robots with Inference-Time Interactions
… Specifically, I propose (1) inference-time steering, which leverages user interactions to switch between discrete skills, and (2) task and motion imitation, which enables user interactions to edit continuous motions while satisfying task constraints defined by discrete symbolic plans. These …

Electromagnetic tracking and steering for catheter navigation
… explores the use of electromagnetics for both steering and tracking of medical instruments in minimally invasive surgeries. The end application is virtual navigation of the lung for biopsy of early stage cancer nodules. Navigation to the peripheral regions of the lung is difficult due to …

Brake-Actuated Steering of Heavy Goods Vehicles
… reduced low-speed manoeuvrability. Active rear-steering technologies have been developed to mitigate this, but they rely on heavy and costly electro-hydraulic actuation systems. This dissertation describes the development of a ‘brake-actuated steering’ (BAS) concept to actively steer articulated …

Tip steering of the Atomic Force Microscope.
… image certain samples. This paper proposes a tip steering method that utilizes the vertical feedback information from the AFM sensor as well as the dimensions of the sample object to determine and maintain a scanning trajectory. A comparison of similar trajectory tracking methods is also …

An Advanced Fast Steering Mirror for optical communication
… assembly, and testing of an Advanced Fast Steering Mirror (AFSM) for precision optical platforms. The AFSM consists of a mirror driven in two rotational axes by normal force electromagnetic actuators, and controlled via position feedback loops. The dynamic performance is sufficient to …

Fault tolerant control for an electric power steering system
Electric power steering (EPS) systems are rapidly replacing existing traditional hydraulic power steering systems due to fuel and cost savings. The reliability of a column mounted EPS is improved by adding an alternate control scheme that is tolerant to a torque sensor failure (FTC). To accomplish …

Scalable Data Paradigms for Steering General-Purpose Language Models
… from the internet. However, effectively steering these models to serve diverse downstream applications, such as following instructions, chatting with users, using tools, or performing complex reasoning, poses another set of challenges that require diverse, high-quality, and increasingly …

Design optimization of articulated vehicles with autonomous steering control
… to the design synthesis of AVs with autonomous steering. A linear yaw-plane model is generated to represent the AV, and a model predictive control (MPC) based tracking controller is designed for steering control. A stochastic modeling technique is developed using Monte-Carlo method to evaluate …

Structure-borne sound transmission within electric power steering systems
… case studies concern a beam and an electric powersteering system with paraxial servo unit (EPSapa), respectively. EPSapa systems consist of multiple embedded vibrational components which are defined as“internal sources”. The electric motor, the ball nut assembly and the toothed belt are …

The Study of Binary Steering Algorithms in Discrete Tomography
In this research project we will study the binary steering technique in iterative methods for image reconstruction in discrete tomography (DT). We will compare the effectiveness of three common algorithms to solve binary systems. The methods used are the Algebraic Reconstruction Technique (ART), …
