Telexistence is fundamentally a concept named for the general technology that enables a human being to have a real-time sensation of being at a place other than where he actually exist, and to interact with the remote environment [Tachi et al. 1990]. We have achieved human-like neck movements to visually interact with a remote object in 3 dimensional space(More)
Co-cultures of human osteosarcoma Takase (OST) cells with various human fibroblasts derived from surgical specimens stimulated production of gelatinase B (92-kDa type-IV collagenase, MMP-9), tissue inhibitors of metalloproteinase (TIMP)-1, and TIMP-2 when compared to cultures of individual cells. The maximum stimulation of gelatinase-B production occurred(More)
The co-cultures of five different human tumor cell lines with human normal fibroblasts significantly stimulated the production of tissue inhibitors of metalloproteinases-1 (TIMP-1) when compared to cultures of individual cells. In the co-culture of T24 human urinary bladder carcinoma cells and CCD18 human fibroblasts, production of both TIMP-1 and(More)
This paper focuses on design of a dexterous anthropomorphic robot where the operator can perceive the transferring bodily consciousness to the slave robot during a tele-operation. Accordingly, we propose a telexistence surrogate anthropomorphic robot called “TELESAR V”, which was designed and constructed by development of the following: a 52(More)
In this paper, we propose a haptic transmission system for telexistence to improve the ability to sense the presence of remote objects. This system can transmit information about the existence and surface textures of objects in remote locations. The system consists of a conjugated haptic sensor and display. The sensor on the robot’s finger detects the(More)
We propose a novel full-parallax three-dimensional (3D) display system-RePro3D-that is suitable for interactive 3D applications with haptic feedback.Our approach is based on the retro-reflective projection technology in which several images projected from a projector array are displayed on a retro-reflective screen. When viewers view the screen through a(More)
