Measuring Spatiotemporal Coordination in a Modular Robotic System

چکیده
In this paper we propose and verify spatiotemporal measures of coordination in a modular robotic system. These information-theoretic measures estimate the generalized “correlation entropy” K2 and the generalized excess entropy E2 computed over a multivariate time series of actuators’ states, while standard deviation of E2 is minimized over both space and time. Actuators are shown to be well-coordinated in individuals with fastest locomotion. These results support our conjecture that direct fitness functions can be approximated with generic selection pressures, leading towards information-driven evolutionary design.

Evolving Spatiotemporal Coordination in a Modular Robotic System
In this paper we present a novel information-theoretic measure of spatiotemporal coordination in a modular robotic system, and use it as a fitness function in evolving the system. This approach exemplifies a new methodology formalizing co-evolution in multi-agent adaptive systems: information-driven evolutionary design. The methodology attempts to link together different aspects of information ...
متن کاملDistributed Coordination in Modular Precision Assembly Systems Distributed Coordination in Modular Precision Assembly Systems
A promising approach to enabling the rapid deployment and reconfiguration of automated assembly systems is to make use of cooperating, modular, robust robotic agents. Over the past 5 years, the authors have been constructing just such a system suitable for assembly of high-precision, high-value products. Within this environment, each robotic agent executes its own program, coordinating its acti...
متن کاملError Recovery by the Use of Sensory Feedback and Reference Measurements for Robotic Assembly
Industrial robots need instrument or parts transport to do which requires coordinate to show the robot’s instrument, parts and body. When investigating the robot location, we are usually interested in measuring its location relative to a reference coordinate system. In this system it is attempted to make the assemble direction smaller by designing the sensor board and making use of an instrumen...
متن کاملA Human-like Robotic Manipulation System Implementing Human Models of Sensory-Motor Coordination
The recent advances of humanoid robotics led to achievements in the development of human-like body parts and whole bodies, as well as of perceptual systems and schemes for behavior planning and learning. For this reason, a step further can be envisaged in the application of human-like robots as experimental tools in neuroscience, for carrying on experiments that may be difficult or impossible w...
متن کاملDesign of PID Controller for Teleopration System with Genetic Algorithm
This paper presents a novel teleoperation controller for a nonlinear master–slave robotic system with constant time delay in communication channel. The proposed controller enables the teleoperation system to compensate human and environmental disturbances, while achieving master and slave position coordination in both free motion and contact situation. The current work basically extends the pas...
