Practical Control for Multicopters to Avoid Non-Cooperative Moving Obstacles

How We Avoid Collisions With Stationary and Moving Obstacles

When moving through cluttered environments we use different forms of the same source of information to avoid stationary and moving objects. A stationary obstacle can be avoided by looking at it, registering the differential parallactic displacements on the retina around it during pursuit fixation, and then acting on that information. Such information also specifies one's general heading. A movi...

Learning to Avoid Moving Obstacles Optimally for Mobile Robots Using a Genetic-Fuzzy Approach

The task in a motion planning problem for a mobile robot is to nd an obstacle-free path between a starting and a destination point, which will require the minimum possible time of travel. Although there exists many studies involving classical methods and using fuzzy logic controllers (FLCs), they are either computationally extensive or they do not attempt to nd optimal controllers. The proposed...

Age effects on strategies used to avoid obstacles

Chen et al.’ found that the rates of success which 24 healthy younger and 24 healthy older adults achieved in not stepping on fixed and suddenly appearing virtual obstacles was adversely affected by reducing their available response time. This paper reports the gait strategies used by those 48 subjects in avoiding the obstacles and the factors associated with falls by four of the subjects. Diff...

Label updating to avoid point-shaped obstacles in fixed model

In this paper, we present efficient algorithms for updating the labeling of a set of n points after the presence of a random obstacle that appears on the map repeatedly. We update the labeling so that the given obstacle does not appear in any of the labels, the new labeling is valid, and the labels are as large as possible (called the optimal labeling). Each point is assumed to have an axis-par...
