This paper reports on a set of theoretical and experimental investigations into the use of force reflection to enhance the dynamic behavior of human piloted vehicles, especially joystickcontrolled vehicles such as fly-by-wire jets, bulldozers, and powered wheelchairs. Briefly, force reflection is used in the manual controls to cancel the effects of feedthrough dynamics. Feedthrough dynamics ref...

The automotive industry may be on the verge of a technological disruption as different alternative fuel vehicles are expected to enter the market. Industry evolution theories are not unified in suggesting the conditions under which different types of entrant technologies can be successful. In particular, the competitive dynamics among a variety of technologies with varying potential for spillov...

This paper develops a dynamic, behavioral model with an explicit spatial structure to explore the co-evolutionary dynamics between infrastructure supply and vehicle demand. Vehicles and fueling infrastructure are complementarities and their "chicken-egg" dynamics are fundamental to the emergence of a self-sustaining alternative fuel vehicle market, but they are not well understood. The paper ex...

Quad-rotors have been a very popular topic for research in the current literature because of its capability to perform different tasks autonomously. This paper focuses on the modeling of a quad-rotor aircraft dynamics based on experimental data. It will be demonstrated that a linear model could represent its dynamics despite of quadrotor's strong nonlinearities. Also, it will be shown how a qua...

Planning is one of the key problems for autonomous vehicles operating in road scenarios. Present planning algorithms operate with the assumption that traffic is organized in predefined speed lanes, which makes it impossible to allow autonomous vehicles in countries with unorganized traffic. Unorganized traffic is though capable of higher traffic bandwidths when constituting vehicles vary in the...

The ow of vehicular traac has been studied in many diierent ways. After an introduction, we will give overview of several models for the ow on single lane road: a uid dynamics theory, a approach based on the dynamics of individual vehicles and a model using a cellular automata. The latter model will be used to study to ow in two dimensions representing the traac in a city with crossings and tra...

This article focuses on theoretical developments in modeling and control of High-Speed Supercavitating Vehicles (HSSV). A simplified model of longitudinal dynamics is developed for control, and a dynamic inversion based inner-loop control technique is proposed to handle the switched, time-delay dependent behavior of the vehicle. Two outer-loop control schemes are compared for guidance level tra...

Considering Unmanned Autonomous Vehicles (UAVs) the planning tasks mainly consist of finding paths between given waypoints with respect to given constraints. In this paper we developed a path planning system for flying UAVs (VTOLs and CTOLs) built upon Hexagonal grids which also supports simple dynamics (handling with speed). The planning system is additionally supported by a trajectory smoothi...
