Rack and Westbury (1969) showed that low frequency asynchronous stimulation of a muscle produces greater force compared to synchronous stimulation. This study tested the hypothesis that the difference results from the dynamic stretch of the common elastic elements. In 8 anaesthetized cats the soleus was attached to a servomechanism to control muscle length and record force. The ventral roots we...

Rack and Westbury showed that low-frequency asynchronous stimulation of a muscle produces greater force compared with synchronous stimulation. This study tested the hypothesis that the difference results from the dynamic stretch of the common elastic elements.

In this paper a servomechanism vision control system, based on hand language, is presented. The control images are acquired by a generic webcam and processed, in the working phase, in quasi real time. For this processing, two approaches were considered: in the first one, we used the object control moments to identify the desired order; in the second approach, we used image control orientation h...

The use of material transfer units constructed from AGVs and robot manipulators is becoming popular in production lines with small production volumes and periods. This new material transfer unit is also called a mobile robot, which can quickly adapt to the change of the factory loyout. A mobile robot is sufficiently mobile that it can very flexibly perform tasks in the production line. A guidan...

A model of the servomechanism used for high-powered actuators in mechanical systems consists of a position feedback loop around the cascade connection of a memoryless saturation function with an integrator with a large time constant. The saturation function in the servomechanism has a linear high gain characteristics for a small input and so the equivalent time constant of the actuator servomec...
