Ultrasonic Polishing [PDF]

open access: yes, 1993
The ultrasonic polishing process makes use of the high-frequency (ultrasonic) vibrations of an abradable tool which automatically conforms to the work piece and an abrasive slurry to finish surfaces and edges on complex, highly detailed, close tolerance ...

Grasping moving objects with incomplete information in a low-cost robot production line using contour matching based on the Hu moments

open access: yesResults in Engineering
In a low-cost system with limited hardware capacity, due to the fast speed of the conveyor and the delay in shooting and processing time, a part of the workpieces may be out of view of the camera. As a result, the information received is incomplete.

Building and Refining Abstract Planning Cases by Change of Representation Language

open access: yes, 1995
ion is one of the most promising approaches to improve the performance of problem solvers. In several domains abstraction by dropping sentences of a domain description -- as used in most hierarchical planners -- has proven useful.
