چکیده
In mobile robotics, obtaining stable image of a mounted camera is crucial for operating a mobile system to complete given tasks. This note presents the development of a high-speed image stabilizing device using linear shaft actuator, and a new image stabilization method inspired by human gaze stabilization process known as vestibulo-ocular reflex (VOR). In the proposed control, the reference is adaptively adjusted by the VOR adaptation control to reject residual vibration of a camera as the VOR gain converges to optimal state. Through experiments on a pneumatic vibrator, it will be shown that the proposed system is capable of stabilizing 10 Hz platform vibration, which shows potential applicability of the device to a high-speed mobile robot.

Multiple timescales in the adaptation of the rotational VOR.
Goal-directed movements, such as pointing and saccades, have been shown to share similar neural architectures, in spite of the different neuromuscular systems producing them. Such structure involve an inverse model of the actuator being controlled, which produces the commands innervating the muscles, and a forward model of the actuator, which predicts the sensory consequences of such commands a...
متن کاملA high speed gaze control system based on the Vestibulo-Ocular Reflex
Stabilizing the visual system is a crucial issue for any sighted mobile creature, whether it will be natural or artificial. The more immune the gaze of an animal or a robot is to various kinds of disturbances (e.g., those created by body or head movements when walking or flying), the less troublesome it will be for the visual system to carry out its many information processing tasks. The gaze c...
متن کاملA neuromuscular model featuring co-activation for driver simulation
This paper covers the development of a neuromuscular model for use in driver simulation, focussing on the inclusion of a representation of co-activation. Co-activation is thought to function as a combination of feed-forward control (based on future predictions of the task being undertaken) and feedback control (to reject disturbances.) A linear model of the neuromuscular system, muscles, limbs ...
متن کاملCerebellar-inspired algorithm for adaptive control of nonlinear dielectric elastomer-based artificial muscle
Electroactive polymer actuators are important for soft robotics, but can be difficult to control because of compliance, creep and nonlinearities. Because biological control mechanisms have evolved to deal with such problems, we investigated whether a control scheme based on the cerebellum would be useful for controlling a nonlinear dielectric elastomer actuator, a class of artificial muscle. Th...
متن کاملFinal Report.dvi
Tension-aligned structures have been proposed for space-based antenna applications. The structure uses a compression member to impart tension on the antenna, thus helping to maintain shape and facilitate disturbance rejection. These structures can be large and are therefore sensitive to low-frequency excitation. Three energy-based control strategies have been proposed for vibration suppression....
