Some descending intemeurones (DNs) in insects encode deviation from flight course. Intracellular recording reveals their inputs (from eyes, wind hairs, proprioceptive information from the neck and in some cases ocelli). Intracellular stimulation during flight reveals their motor effects. All components of steering (modification of wing stroke, ruddering with the hind legs, ruddering with the ab...

Insect antennae are sensory organs involved in a variety of behaviors, sensing many different stimulus modalities. As mechanosensors, they are crucial for flight control in the hawkmoth Manduca sexta. One of their roles is to mediate compensatory reflexes of the abdomen in response to rotations of the body in the pitch axis. Abdominal motions, in turn, are a component of the steering mechanism ...

This paper addresses the problem of path following for unmaned cars using only GNSS positionning. Several papers have already addressed the lane keeping, usually restricting the focus to the computation of the optimal steering wheel angle, therefore usually offering a good solution in either straight lines or curves, but rarely both. Moreover the GNSS receiver have a sampling time higher than t...

This paper presents two major components of an automatic parking assist system (APAS). The APAS maps the environment of the vehicle and detects the existence of accessible parking place where the vehicle can park into. The two most important tasks the APAS must then realize are the design of a feasible path geometry and the tracking of this reference in closed loop such that the longitudinal ve...

The authors investigated the dynamics of steering and obstacle avoidance, with the aim of predicting routes through complex scenes. Participants walked in a virtual environment toward a goal (Experiment 1) and around an obstacle (Experiment 2) whose initial angle and distance varied. Goals and obstacles behave as attractors and repellers of heading, respectively, whose strengths depend on dista...

Turning back after engine failure during the take off phase of flight in a single engine aircraft is examined using a simplified analytical model. The important parameters are identified. The analysis shows that the optimum flight path is teardrop shaped with a 45◦ bank angle at stall velocity during the turn. The effects of engine failure altitude, wind direction and velocity, and bank angle o...

This paper presents an impact-angle-control guidance law with terminal constraints on the curvature of missile trajectory. The formulation takes into account nonlinear kinematics and time-varying velocity, allowing for more general cases in which flight path angle may not be small throughout entire proposed optimal aims to minimize change rate pseudo-curvature, is defined as a weighting factors...

Drivers of man-machine cooperative driving intelligent vehicles are affected by skills, physiological reactions, and other factors. Under emergency conditions, they often subconsciously forcefully take over control rights produce unreasonable stress steering, which brings new accident risks to vehicles. To avoid collisions, this paper proposes an collision avoidance strategy for In the path pla...

This paper describes an ongoing design and development project of an autonomous pathtracking forest machine. The work is part of a long-term vision in the forest industry of developing an unmanned shuttle that transports timber from the felling area to the main roads for further transportation. The developed prototype system has two modes of operation: Path Learning, in which the human operator...
