We aim to investigate biological function of emotional bodily movements while building a robot in the sense of survival. In this particular paper, we build a novel active vision system which detects weak signals by generating tremor actively. Proposed active vision system consists of a noise generator and a neural system. As a noise generator, we use motors(More)
In this paper, synthetic research for primevaloids, robots of primitive appearance, is described. First, we briefly introduce goals of the project within a perspective of entertainment robotics. Next, we sketch design concepts and prospective principles for a novel kind of entertainment robots, while placing our emphasis on primeval appearance,(More)
In this paper, characteristics of a sensory-motor system driven by coupled bursting neurons are examined. We constructed a sensory-motor system by connecting networks of coupled bursting neurons. Mutually connected networks showed several kinds of oscillation rhythms. When networks oscillate at 5-10 Hz, a robot pushed an object in an environment, and when(More)
The effective noise intensity D that is used to evaluate theoretical value of 〈C1〉 throughout the original paper is inaccurate. In Sec. III A, we derived the piecewise-linear FitzHugh-Nagumo (plFHN) neuron model, and we introduced the noise scaling ξ (t) → 7τξ (t̃) in correspondence with the time scaling t → 7τ t̃ . However, the noise should be scaled as ξ(More)

A spherical mobile robot has been developed with a 1-DOF mechanism that can generate two motions, translational and rotational, using only one motor. The basic concept is to attach vinyl strips to the sphere at regular intervals and to change the driving modes of the motor to produce the desired motion. For example, placing the motor in vibration mode(More)
The presence of noise can improve the response of certain nonlinear systems to input signals through the effects of stochastic resonance (SR). The optimal noise intensity for SR is proportional to the signal frequency if the signal is periodic, but proportional to the signal intensity if the signal is aperiodic. Here, we demonstrate using linear response(More)
