A simple, short and efficient chaotic path planning algorithm is proposed for autonomous mobile robots, with the aim of covering a given terrain using chaotic, unpredictable motion. The proposed technique utilizes the logistic map with a chaotic tactic that utilizes a modulo function to produce a se ...

In the research on chaotic systems, which are used for cryptography and secure communication schemes, a key characteristic is the introduction of novel chaotic systems, usually by adding complexity to the existing ones in order to ensure security. In this direction, this chapter proposes novel chaot ...

This work, presents the design and the implementation of a mobile robot that can cover given workspaces. The motion commands have been produced by a chaotic system which gives high "randomness" to its behavior. For the implementation of the robot a microcontroller has been used (Arduino Uno). Moreov ...

This paper investigates the issue of chaos-based image encryption. A new one-dimensional piecewise chaotic map based on the z-shaped fuzzy number is proposed and investigated, exhibiting regions of constant chaos and high Lyapunov exponent values. A pseudorandom bit generator based on the novel chao ...

This paper proposes a new one-dimensional chaotic map. The map consists of a coupling between two hyperbolic tangent terms, where the second term is delayed, to avoid dynamical degradation. The map is studied through computation of its bifurcation diagrams and Lyapunov exponent diagrams and is shown ...

In this work, a novel hyperjerk system, with hyperbolic sine function as the only nonlinear term, is proposed, as a modification of a hyperjerk system proposed by Leutcho et al. First, a dynamical analysis on the system is performed and interesting phenomena concerning chaos theory, such as route to ...

Typically, chaos-based encryption applications are concerned with encrypting a single type of data, such as an image, text, or sound. Hence, often an encryption approach is restricted to that type of data. This paper explores the aforementioned problem and proposes a novel chaos-based encryption, wh ...

This work proposes a chaotic text encryption scheme implemented in a microcontroller device. Initially, a chaotic 1D map is proposed and studied through its bifurcation diagrams and Lyapunov exponent diagram. The map showcases a constant chaotic behavior, which makes it suitable for use in encrytpti ...

This work considers the problem of chaotic path planning, using an improved memory technique to boost performance. In this application, the dynamics of two simple chaotic maps are first used to generate a pseudo-random bit generator. Using this as a source, a series of navigation commands are genera ...
