A Dynamic Compensation for Roll Hemming Process

A 3D passive dynamic biped with yaw and roll compensation

Autonomous walking bipedal machines, possibly useful for rehabilitation and entertainment purposes, need a high energy efficiency, offered by the concept of ‘Passive Dynamic Walking’ (exploitation of the natural dynamics of the robot). 2D passive dynamic bipeds have been shown to be inherently stable, but in the third dimension two problematic degrees of freedom are introduced: yaw and roll. We...

A roll-to-roll welding process for planarized silver nanowire electrodes.

We demonstrate continuous roll-to-roll production of highly conductive silver network films on a plastic substrate via mechanical and chemical welding processes. This process included three essential steps: (i) solvent spraying, (ii) roll compression, and (iii) salt treatment and washing. The sheet resistance of the resulting AgNW film was 5 Ω sq(-1) at 92% transmittance, which was the lowest s...

Anode Layer Linear Ion Source for Roll-to-Roll Process from 300 mm to 1550 mm

Roll-to-roll (RTR) process requires a linear surface treatment source in various processes such as pre-treatment, etching, and deposition. For high speed and large width processes the linear source should have superior characteristics that can be applied to 100~300 m/mim process and large width treatment up to 2 m. Several linear surface treatment sources have been proposed to the RTR process. ...

A Control Method Based on Dynamic Response of the Airplane for Compensation of Pilot-Induced Oscillations: Benefits and Flaws

Pilot-Induced Oscillation (PIO) is an unwanted, inadvertent phenomenon that has the ability to damage the aircraft completely. This paper suggests a novel control method that can damp PIO after predicting its occurrence. The specific point of this control algorithm is that it contains a preprocessor that will not let the controller be activated unless in the case of probable PIOs, so pilot comm...
