Lamarck formed the hypothesis Inheritance of acquired characteristics, which states that offspring inherit characters acquired by their parents. However, this hypothesis has now been rejected in the field of genetics. Baldwin offered an explanation for observations of inheritance of acquired characters, despite the fact that they are not inherited; an idea referred to as the Baldwin effect. To verify...
Usually, robots have some sensors that measure the distance between the robots and any obstacles, for example, ultrasonic sensors, infrared distance sensors, and etc. On the other hand, although animals and insects do not have distance sensors, they can behave adaptively in unknown environments. The mechanism of adaptive behavior has been studied in ecological psychology, and it is assumed that animals...
Recently, swarm intelligence has been actively studied and has been applied for various robots. Realization of flock behaviors by mobile robots is one of them. In conventional works of applications of flock behaviors, environments are modeled as three-dimensional space by using distance sensors, and flock behaviors are realized based on the distance information. However, the conventional framework...
In this paper, we focus on the concept of time to contact and propose a simple sensor system for detecting the time to contact, and apply it to autonomous control of a flying robot. To discuss the effectiveness of the proposed sensor system and a controller using the sensor system, we develop a flying robot simply without CPU(s) or high spec sensors. We employ only 5 CdS cells and simple analogue...
In this paper, we propose the design of a robot with a snake-like body based on a test environment. We explore the abstraction of state-action spaces for reinforcement learning. Additionally, we discuss the versatility of the proposed mechanism by showing that different tasks can be completed by simply changing the reward of the reinforcement learning. Finally, we mention the importance of a body...
In this paper we consider autonomous control of a snake-like robot using reinforcement learning. Conventional methods of reinforcement learning have significant problems in practical use. That is curse of dimensionally and lack of generality. To solve these problems, we focus on design of the mechanical body of the snake-like robot, and abstract necessary small state-action space from complex environments...
