This paper provides a solution to the nonplanar multiagent formation control problem using graph rigidity. We consider a 3-D multiagent formation control where multiple agents are operating in one plane and some other agents are operating outside of that plane. This can be referred to as a layered formation control where the objective is for all agents to cooperatively acquire a predefined formation...
Obtaining methodologies that enable predictive health monitoring of components degradation and the propagation of related effects across the overall system is a need when designing complex systems (such as autonomous vehicles, robotic systems, and aerospace platforms). In this paper, a current software development is presented for workflow generation and visualization to evaluate how component degradation...
This paper addresses the decentralized formation control problem of unmanned vehicles in three-dimensional (3D) space. We propose a new Neural Network-based control algorithm that uses graph rigidity and relative positions of the vehicles. The control law for each vehicle consists of a nonlinear component that is dependent on the closed-loop error dynamics plus a neural net component that is linear...
This paper is concerned with the evaluation and comparison of several methods for the classification and recognition of static hand postures from small unlabeled point sets corresponding to physical landmarks, e.g. reflective marker positions in a motion capture environment. We compare various classification algorithms based upon multiple interpretations and feature transformations of the point sets,...
We present a distance metric based upon the notion of minimum-cost injective mappings between sets. Our function satisfies metric properties as long as the cost of the minimum mappings is derived from a semimetric, for which the triangle inequality is not necessarily satisfied. We show that the Jaccard distance (alternatively biotope, Tanimoto, or Marczewski-Steinhaus distance) may be considered the...
In this paper, we present an algorithm for navigating an unmanned ground vehicle (UGV) through coordinate-free Wireless Sensor and Actuator Networks. The navigation algorithm proceeds in two phases. In the first phase, for each node in the sensor network we compute a hop-level distance from the target node, which indicates the number of communication hops between the node and any destination nodes...
