Due to the confined intraocular space and physical constraints in tool manipulation, snake-like robots have a significant potential for use in retinal microsurgery. By enhancing the dexterity at the tool tip, not only the operable space on the retina can be enlarged, but also the delicate target tissues can be reached at an optimal angle minimizing the damage and making the operation much easier....
The drag coefficient and Magnus coefficient are different along with the geometric parameters of target object when calculating and simulating the trajectory. Generally, the coefficients are measured in wind-tunnel via repeated experiments, and only for object which have the same shape and geometric parameters. This paper proposes a numerical iterative algorithm based on hierarchical optimization...
In order to eliminate the influence on the immersion and realism for virtual reality simulation system environment, which is resulted from the color difference of the multi-projector display system, an optimization color correction algorithm based on projector-camera system is proposed. It considers the non-linear influence of both camera and projector. Unlike previous work, where the affection of...
Augmented reality assembly, is a promising application of virtual reality in design and manufacturing and has drawn much more and more attentions from industries and research institutes. The focus of this study are as follows. (1) using the agent-oriented modeling for subassembly object and the behavior reasoning based on petri net model of environment, to build the system model of augmented reality...
According to the theory of spherical robot which invented by our laboratory, we designed a novel designed two-wheeled robot It possesses many salient advantages when compared to traditional mobile robots for its special characters, including self-balance, anti-overturn, and the rests. Its primary driving-method and structure-design arc analyzed and optimized in this paper. Moreover, in this paper,...
Realizing the virtual manufacturing lies in the support of immersive virtual environment, human-computer interactive tools, and software making the virtual objects, and virtual environment is the overriding condition of virtual manufacturing. Large-format tiled displays are an emerging technology for constructing large scale, high-resolution, semi-immersive visualization environments capable of presenting...
