| Abstract | |
In recent years, aerial robots have become increasingly important in day-to-day situations, in several uses, in which we can highlight: public and private security, precision agriculture, photographic record of events, delivery and support to several other areas, such as environmental monitoring. In order for aerial robots perform their broad range of tasks, a motion planning step is necessary. Motion planning consists in finding a feasible path between the current posture and a final posture (also called target posture or goal) of a robot. In this work, the task of motion planning is approached in three-dimensional and dynamic environments, in which it is not assumed that all the obstacles will remain fixed along the trajectory. Derived from Harmonic Potential Field Theory, Modified Potential Fields (MPF) allows a controlled distortion of the potential field, as an example, towards a specific direction of arrival to the target posture. Such MPF results in a motion planner for dynamic and multidimensional environments, especially the three-dimensional case. (AU) | |
