چکیده
We present a probabilistic method for noisy sensor based robotic navigation in dynamic en vironments The method generates an optimal trajectory by considering as optimality criteria the probability of not colliding with the obstacles and the probability of accessing an operational position with respect to a moving target object Estimates of the obstacle s kinematic parameters and measures of con dence in these estimates are used to produce the probability of collision associated with any robot displacement The probability of collision is derived in two steps a stochastic model is de ned in the kinematic state space of the obstacles and collision events are given simple geometric characterizations in this state space The support of the Defense Advanced Research Projects Agency ARPA Order No and the U S Army Engineer Topographic Laboratories under Contract DACA C is gratefully acknowledged as is the help of Sandy German in preparing this paper

Navigation with uncertainty: reaching a goal in a high collision risk region
We present a probabilistic method for noisy sensor based robotic navigation in dynamic environments. The method generates an optimal trajectory by considering as optimality criteria the probability of not colliding with the obstacles and the probability of accessing an operational position with respect to a moving target object. Estimates of the obstacle's kinematic parameters and measures of c...
متن کاملPerception-aware Receding Horizon Navigation for MAVs
To reach a given destination safely and accurately, a micro aerial vehicle needs to be able to avoid obstacles and minimize its state estimation uncertainty at the same time. To achieve this goal, we propose a perception-aware receding horizon approach. In our method, a single forwardlooking camera is used for state estimation and mapping. Using the information from the monocular state estimati...
متن کاملIdentifying at Highway-Rail Grade Crossing Hotspots in Canada
This research presents a risk-based Hotspots identification model at highway-rail grade crossings in Canada. Two sets of models were developed to predict collision frequency and consequence at individual crossings. A two–dimensional graphic approach was adopted to combine these two models together to predict the risk at each crossing. Hotspots based on collision history tended to be widespread ...
متن کاملMobile Robot Collision Avoidance in Human Environments
Collision avoidance is a fundamental requirement for mobile robots. Avoiding moving obstacles (also termed dynamic obstacles) with unpredictable direction changes, such as humans, is more challenging than avoiding moving obstacles whose motion can be predicted. Precise information on the future moving directions of humans is unobtainable for use in navigation algo...
