A research team at Saarland University has developed a new robot suction gripper that can quickly adapt to various workpieces. The gripper consists of artificial muscles made of nickel-titanium, which move its fingers and can create a strong vacuum. The system enables more flexible production and manufacturing and only requires electrical power. The artificial muscle fibers allow for fast movements and high pulling force. The gripper can hold objects firmly and move freely in space without the need for compressed air, and it operates quietly. Control is done through a semiconductor chip that provides all the data and enables precise movements. The system can reprogram itself and can determine whether it securely grips the workpiece. The research team has founded the company mateligent GmbH to bring these and other intelligent material systems into industrial practice. [Extracted from the article]

Increasing the amount of renewables in traction power mix is a great challenge for DB AG. The problems are quite similar to 50 Hz grid, but it's even more difficult within a smaller system on 110 kV and 16,7 Hz frequency. Three green options have been evaluated based on technical, economical and ecological criteria The result was a fixed set of instruments to reach 35% renewables until 2020. [ABSTRACT FROM AUTHOR]

ROBEL Bahnbaumaschinen GmbH introduces the new clipping machine 34.02. It is characterised by a modular design based on the working conditions on the track, economic efficiency and ergonomics. It enables the combination of different work modules - for different types of rail clip such as e-Clip, Fast-Clip, etc. - with a variety of power packs. The machine may be powered electrically or by a combustion engine and can be easily re-tooled for different clipping requirements. This goes hand in hand with a high degree of ergonomics. The highly ef-fective de-coupling of the vibrations between the power pack and the work module benefits the operator considerably. The separable design ensures a high degree of transportability of the compact and comparably light modules. [ABSTRACT FROM AUTHOR]
