Phase automata: a programming model of locomotion gaits for scalable chain-type modular robots

چکیده
− Modular reconfigurable robots have shown the promises of great versatility and robustness; however programming locomotion gaits for hundreds of modules remains a challenge. In this paper we present a formal model for programming locomotion gaits in chain-type modular robots: Phase Automata. A phase automaton is an event-driven state automaton with an initial phase delay. The phase delay is normally a real value between 0 and 1. Phase automata are compact representation of locomotion gaits and capable of being embedded and distributed across modules. The concepts of phase automata have been implemented on both PCs and embedded micro-processors. An XML script language and programming interface for phase automata are being built. Locomotion gaits programmed using phase automata have been tested both in simulation with 100+ modules and in hardware with 50+ modules.

Scalable and reconfigurable configurations and locomotion gaits for chain-type modular reconfigurable robots
Modular reconfigurable robots have shown the promises of great versatility and robustness; however they also impose design challenges on mechanical, electronic and software scalability. In this paper, we present a class of configurations that are scalable mechanically and electronically. Moreover, there exists a predefined reconfiguration sequence between any of the three configurations, namely...
متن کاملAn XML-based Scripting Language for Chain-type Modular Robotic Systems
A number of modular robotic systems have been developed over the last decade. Such systems promise increased flexibility and robustness and lower cost over conventional robots; however programming systems with many degrees of freedom is still more an art than engineering. The complexity of programming limits the usage of such systems and the sharing of knowledge within the modular robotics comm...
متن کاملBio-inspired locomotion for a modular snake robot [7321-14]
Inspired by the snake locomotion, modular snake robots have different locomotion capabilities by coordinating their internal degrees of freedom. They have the potential to access restricted spaces where humans cannot go. They can also traverse rough terrains while conventional wheeled and legged robots cannot. Modular robots have other features including versatility, robustness, low-cost, and f...

Modular robots offer the possibility to design robots with a high diversity of shapes and functionalities. This nice feature also brings an important challenge: namely how to design efficient locomotion gaits for arbitrary robot structures with many degrees of freedom. In this paper, we present a framework that allows one to explore and identify highly different gaits for a given arbitraryshape...
متن کاملLocomotion Capabilities of a Modular Robot with Eight Pitch-Yaw-Connecting Modules
In this paper, a general classification of the modular robots is proposed, based on their topology and the type of connection between the modules. The locomotion capabilities of the sub-group of pitch-yaw connecting robots are analyzed. Five different gaits have been implemented and tested on a real robot composed of eight modules. One of them, rotating, has not been previously achieved. All ga...
