چکیده

In recent years, evolutionary algorithms (EAs) have been successfully used in the design of artiicial neural networks for a variety of applications. The suitability of EAs for this design task stems from their ability to adaptively search large spaces in near-optimal ways. One direct application of this advance has been in the area of evolutionary robotics, where EAs are typically used for designing behavior controllers for robots and autonomous agents. While such designs have been found to work well in general, their performance is often limited by the number, placement, quality, eecacy, and reliability of the sensors that the robots are endowed with. In this paper we argue that designing the sensory systems of these robots, in addition to the usual practice of designing the controller, can lead to improvements in the performance of the robot. Our results indicate that the evolution of sensors is a useful enterprise, and can lead to eecient and often counterintu-itive controller designs.

Application of Piezoelectric and Functionally Graded Materials in Designing Electrostatically Actuated Micro Switches

In this research, a functionally graded microbeam bonded with piezoelectric layers is analyzed under electric force. Static and dynamic instability due to the electric actuation is studied because of its importance in micro electro mechanical systems, especially in micro switches. In order to prevent pull-in instability, two piezoelectric layers are used as sensor and actuator. A current amplif...

Autonomous Evolution of Gaits with the Sony Quadruped Robot

A trend in robotics is towards legged robots. One of the issues with legged robots is the development of gaits. Typically gaits are developed manually. In this paper we report our results of autonomous evolution of dynamic gaits for the Sony Quadruped Robot. Fitness is determined using the robot's digital camera and infrared sensors. Using this system we evolve faster dynamic gaits than previou...

Computer Evolution of Buildable Objects

Creating artificial life forms through evolutionary robotics faces a “chicken and egg” problem: learning to control a complex body is dominated by inductive biases specific to its sensors and effectors, while building a body which is controllable is conditioned on the pre-existence of a brain. The idea of co-evolution of bodies and brains is becoming popular, but little work has been done in ev...
