This paper solves the problem of intercepting a moving object in FIFO graphs. In the graph, a first mobile (the target) is moving with a known fixed itinerary. The second mobile (the pursuer) aims to reach the first one with the minimum delay. So, our goal is to find the shortest path for the interception taking into account the dynamic nature of the graph. This interception problem can be appl...

In this paper, we present a generic task-allocation methodology for time-optimal, autonomous on-line interception of multiple dynamic targets by a team of robotic pursuers. The proposed novel methodology is applicable to problems consisting of numerous variations of multiple pursuers and targets. The targets are assumed to be highly maneuverable with a priori unknown, though real-time trackable...

This paper discusses a control algorithm for the interception of a mobile target. The application domain is robot soccer in which the target is a ball while the interceptor is a wheeled robot. A case study of a wheeled robot approaching a target in a given direction is presented in detail. A shoot function has been developed, using the proposed algorithm, which calculates the robot wheel veloci...

Near-space-gliding vehicles have variable maneuver modes and dramatic changes in their ballistic parameters, which lead to a need accurately predict an intercept point based on predictions of trajectories. First, trajectory prediction method builds set time-varying models flight missions combined with adaptive grid infer modes. An interactive multiple-model structure is proposed identify the ch...

Ballistic target interception requires high accuracy in order to achieve kinetic hit-to-kill performance. Since the task becomes more challenging when the target performs complex maneuvers, highly accurate state estimators are indispensable for successful ballistic target interception. This research focuses on developing filter motion models which can reproduce a wide variety of target motions ...

Most agronomic models estimate canopy light interception using the Beer-Lambert law. This method only accounts for leaf area index (LAI) and leaf angle distribution (LAD) without considering the crop’s structural heterogeneity in space, or soil-leaf or leaf-leaf radiative scattering. These factors have been extensively studied during the past ten years e.g; (Luquet et al. 1998; Nouvellon et al....
