One of the key challenges in additive manufacturing processes is to slice 3D CAD models with a simple and efficient algorithm. This paper proposes a new algorithm of slicing CAD models which are represented in STL format into a set of layers. In this algorithm, the 3D model should be saved as STL format file. According to the required thickness of layers, the 3D model can be sliced into a series of...
This paper presents a 3D path planning approach for UAV navigation given a mission task specified by a sequence of midway points and required orientation at each point. The approach developed was inspired by the Dubins 2D airplane algorithm. To avoid the difficulty of direct extension to 3D, the heading adjusting is undertaken in horizontal 2D plane at different altitude and the z motion is applied...
Flocking with obstacle avoidance of multi-agents is a significant problem. In this paper, a flocking algorithm in the presence of arbitrary shape obstacles avoidance is provided both in 2D space and 3D space. When obstacles are sensed by α-agents, β-agents which denote obstacles will guide the α-agent driving away from obstacles in a fastest route. We present an approach to determine the position...
