This paper describes a novel fabric manipulation method for fabric control during the sewing process. It addresses issues with past attempts concerning fabric position and tension control. The method described involves ...

An advanced backhoe user interface has been developed which uses coordinated control with haptic feedback. Results indicate that the coordinated control provides more intuitive operation that is easy to learn, and the ...

This research investigates and seeks to mitigate the undesirable effects of biodynamic feedthrough in backhoe operation. Biodynamic feedthrough occurs when motion of the controlled machine excites motion ...

In some operator-controlled machines, motion of the controlled machine excites motion of the human operator, which is fed back into the control device, causing unwanted input and sometimes instability; this phenomenon is ...

A large experimental lightweight manipulator would be useful for material handling, for welding, or for ultrasonic inspection of a large structure such as an airframe. The flexible parallel link mechanism is designed ...

Attempts to automate the sewing process of garment manufacture have employed substitutes for human guidance of fabric into somewhat conventional sewing machines. A new approach has been proposed and partially verified in ...

Precise knowledge of the end-effector position of long-reach, lightweight manipulators is important because the inherit flexibility can cause deflections and vibrations of the structure. A non-contact, low-cost ...
