Steer by wire system can be free to design steering force transmission characteristics and angular displacement transfer characteristics, which can realize the coordination of portability, the driver steering road feel and handling stability. The dynamics models of steer by wire and vehicle system are established. Control strategy of front wheel angle based on fuzzy adaptive PID control is put ...

How do people walk to a moving target, and what visual information do they use to do so? Under a pursuit strategy, one would head toward the target's current position, whereas under an interception strategy, one would lead the target, ideally by maintaining a constant target-heading angle (or constant bearing angle). Either strategy may be guided by the egocentric direction of the target, local...

This paper studies the scaling of airplane dynamic response to stochastic wind gusts, with focus on the relationship between airplane size and airspeed variations. The results have applications in the design and control of small-scale aircraft for robustness with respect to turbulence. Using linearized equations of motion and the Dryden model of gusts, the paper presents analytical and numerica...

This research paper proposes a real-time obstacle avoidance strategy for mobile robots with monocular camera. The approach uses binary semantic segmentation FCN-VGG-16 to extract features from images captured by the camera and estimate position distance of obstacles in robot’s environment. Segmented are used create frontal view robot. Then, optimized path planning based on enhanced A* algorithm...

Title of Thesis: A COUPLED INTERPLANETARY – ENTRY, DESCENT AND LANDING TARGETING PROCEDURE Jeremy David Shidner, M.S., 2006 Thesis Directed by: Dr. Robert Tolson National Institute of Aerospace In NASA’s past, targeting to a Mars landing site has required iteration between the Entry, Descent and Landing (EDL) analysts at NASA Langley Research Center and the interplanetary navigators at the Jet ...

Intelligent path planning of multiple mobile robots has been addressed in this paper. Cooperative behaviour can be achieved using several mobile robots, which require online inter-communication among themselves. In the present investigation rule-based and rule-based-neuro-fuzzy techniques are analyzed formultiplemobile robots navigation in an unknown or partially known environment. The final ai...

The subject of motion planning for non-holonomic wheeled mobile robots moving on the plane and in particular the use of fuzzy and evolutionary strategies for achieving such motion tasks has been dealt with in this paper. The specific robotic system considered is a vehicle whose kinematics approximates that of a car. The configuration of this robot is represented by position and orientation of i...

Active beam-steering devices near the optical frequencies have long been sought after due to their applications in communication, defense, and display technologies; however, the challenge lies in achieving actively tunable structures near these frequencies. An array of metal-dielectric-metal plasmonic resonators is demonstrated as a dynamic beam-steering device to operate at midinfrared wavelen...

The paper describes an application of the A* algorithm for flight path planning for airplanes with defined motion dynamics operating in a continuous three-dimensional space constrained by existing physical obstacles. The presented A* algorithm modification provides significant acceleration (reduction of the state space) of the path planning process. The described algorithm is able to find a pat...

This study addresses the flight-path planning problem for multirotor aerial vehicles (AVs). We consider the specific features and requirements of real-time flight-path planning and develop a rapidly-exploring random tree (RRT) algorithm to determine a preliminary flight path in three-dimensional space. Since the path obtained by the RRT may not be optimal due to the existence of redundant waypo...
