The factors that influence the probability of failure-free robots of mobile robots for military purposes are determined when they are hit by bullets, fragments, explosions and other shock loads. It has been established that the areas of greatest danger for special-purpose mobile robots are the barrel group, actuators, guidance system, ammunition stores, etc. On this basis, recommendations have been developed to improve the survivability of military mobile robots.

Good Coincidence

As part of a guidance system for mobile robots operating on a wide and flat floor, such as an ordinary factory or a gymnasium, we have proposed a special-purpose sign. It consists of a cylinder, with four slits, and a fluorescent light, which is placed on the axis of the cylinder. Two of the slits are parallel to each other, and the other two are angled. A robot obtains an image of the sign with a TV camera. After thresholding, we have four bright sets of pixels which correspond to the four slits of the cylinder. We compute by measuring the relative distances between the four points, the distance and the angle to the direction of the sign can be computed using simple geometrical equations. Using a personal computer with an image processing capability, we have investigated the accuracy of the proposed position identification method and compared the experimental results against the theoretical analysis of measured error. The data shows good coincidence between the analysis and the experiments. Finally, we have built a movable robot, which has three microprocessors and a TV camera, and performed several control experiments for trajectory following.

Die Produktion ist geprägt durch einen Antagonismus aus Flexibilität und Produktivität. Autonome Roboter mit maschinell erlernten Fähigkeiten weisen Potenzial auf, das Spannungsfeld zu entlasten. Allerdings bedarf es aufgrund von Fehleranfälligkeit solcher Systeme Strategien zur Entstörung. Im Beitrag vorgestellt werden Methoden für die Vorortunterstützung mittels Werkerführung sowie zur Entstörung aus der Ferne mittels Teleoperation.   Production is characterized by an antagonism between flexibility and productivity. Autonomous robots with learned skills show potential for relieving existing challenges. However, present failure susceptibility requires efficient intervention strategies to allow a technology establishment. This paper presents methods for on-site support based on a factory worker guidance system as well as remote assistance through tele-operation.

Metal Structures

A stochastic approach has been developed to evaluate fatigue strength using elements of the fracture mechanics. The article presents a method for determining the initial parameters of statistical distributions. It also considers the method for constructing a fatigue curve for a component of any size and configuration with any given probability of failure.
