In this paper we describe mechanical and electronic design of a precision, 2-DOF robot manipulator. The manipulator is one of a wide variety of modular robotic agents in the minifactory, a rapidly depoyable precision assembly system under development in our laboratory. The manipulator, in cooperation with another type of 2-DOF robot, termed a courier, can perform 4-DOF assembly operations emula...

By Hrishikesh S Joshi, M.S. Washington State University December 2006 Chair: Sankar Jayaram Virtual assembly technology is revolutionizing the way we design mechanical assemblies. This technology enables the users to interact with virtual models of mechanical assemblies in an immersive environment. The user interacts with the virtual environment via various hardware devices, which can track mot...

This paper presents design, fabrication, and characterization of easy-to-handle electroplated nickel microgrippers with SU-8 adaptors for heterogeneous micro/nano assembly applications. Two distinctive designs of microgrippers as end-effectors of micro/nano assembly applications have been developed in this work. The first design is 200 lm thick electroplated nickel microgripper with a plastic m...

Reduced graphene oxide/poly (ionic liquid) functionalized nano-fibrillated cellulose composite paper with significant enhancement of mechanical strength, ductility, toughness and hydrophobicity was fabricated by vacuum filtration assisted assembly.

Semantic segmentation of mechanical assembly images provides an effective way to monitor the process and improve product quality. Compared with other deep learning models, Transformer has advantages in modeling global context, it been widely applied various computer vision tasks including semantic segmentation. However, pays same granularity attention on all regions image, so some difficulty be...
