A suitable trajectory in a port inspection mission is important for unmanned aerial vehicles (UAVs). Motion planning can help UAVs quickly generate an optimal that meets the constraints. The motion of achieved this paper as follows: firstly, collision detection (CD) function applied evaluates whether bias_RRT* (rapidly exploring random tree) algorithm needs to be called. Secondly, isosceles tri...

We present several new contributions in sampling-based coverage path planning, the task of finding feasible paths that give 100% sensor coverage of complex structures in obstaclefilled and visually occluded environments. First, we establish a framework for analyzing the probabilistic completeness of a sampling-based coverage algorithm, and derive results on the completeness and convergence of e...

Integrated development of machining and inspection plans is essential in dynamic manufacturing environments, especially when right first time manufacturing is required. In this work, a methodology, based on a new and extended use of tolerance charting, that allows incorporation of in-process inspection operations to improve process plans is presented. The methodology proposes the transfer of th...

<abstract><p>Maritime transportation plays a significant role in international trade and global supply chains. Ship navigation safety is the foundation of operating maritime business smoothly. Recently, more attention has been paid to marine environmental protection. To enhance reduce pollution environment, various regulations conventions are proposed by organizations local governme...

Abstract To improve the inspection efficiency of free-form surfaces using coordinate measuring machines (CMMs), this paper proposes a CMM path optimization method based on an improved ant colony optimisation algorithm. The composition and its mathematical model are first analysed, then algorithm is applied to minimize objective function. address problem that has difficulty jumping out local opt...

Recent times are witnessing an emergence of sites that hazardous for human access. This has created a global demand to equip agents with the ability autonomously inspect such environments by computing coverage path effectively and efficiently. However, inspection requires consider correlation work, providing precedence provision in visiting regions. The current approaches compute sites, however...
