Robot manipulator usage for measurement in production areas

Kuts V., Tahemaa T., Otto T., Sarkans M., Lend H.

Journal of Machine Engineering

2016

Vol. 16, No. 1

57--67

Measuring and inspection works in production process using laser scanners attached to the robot manipulators are more and more used in different ways and purposes. The aim of this article is to study and analyze the usage of 3D measuring devices attached to the robot manipulator according to determine the range and the purpose of such industrial measurements. Different scanning devices are applied in production areas with varying purposes, such as 3D scanning of the new product, in order to inspect and find defects. Attached to the robot manipulator, scanners or laser measuring devices are able to scan every object in range of a robot, which makes the measuring process very flexible. Several tests with 3D scanners were performed to find out the optimal conditions and configuration for production purpose. As a result, knowledge base suitable for different production areas was developed. Thus, it would be feasible to have a common database to be implemented in different production areas.

A Device for Preventing Occupational Diseases of Lower Legs

Kristjuhan U., Reedik V., Tahemaa T.

International Journal of Occupational Safety and Ergonomics

1998

Vol. 4, No. 1

69--74

Physiological processes characteristic of the fatigue of legs mainly appear when the worker’s activity requires standing. If the processes are intensive and regular, various diseases of legs, such as varicose veins and musculoskeletal disorders of legs and feet, can develop. Therefore, methods of reducing the fatigue of legs are important in occupational health protection. Air jet massage technology was developed and an appropriate massage device was built by the authors. The massage head turning around the lower leg and moving up and down gradually covers the leg’s surface. To determine the efficiency of the massage, fatigue processes were studied. These studies showed that jet massage effectively reduces both the subjective and objective fatigue symptoms. The device is convenient for use in industry, services, and at home.
