Development of Telexistence Robot that allows operator to clearly see, hear, and feel the haptic sensation

  • As part of the CREST Strategic Basic Research Program, Project Professor TACHI Susumu and his research group (Keio University) have developed a feel transmission technology to reproduce the sensations of pressure, vibration perception, and temperature perception. By combining this technology with the teleoperator robot, an operator can clearly see, hear, and feel the haptic sensation. The utilization in various fields, such as remote communication, remote experience of a trip or of shopping, the work under the extreme conditions, telemedicine, nursing care, the service industry, and the entertainment field, is expected.
Technology developed for wireless beaming of data between layered stacks of chips, with world-beating ultra-low energy consumption.
Capable of transmitting the equivalent of 6 million images using the energy from a single button battery cell.

As part of the CREST Strategic Basic Research Program, Professor KURODA Tadahiro (Keio University) has succeeded in developing technology for wireless transmission of data at the 0.01 pJ/b level (picojoule/bit is a measure of energy required for data transmission: 1 picojoule is equivalent to 100 trillionth of 1 joule). Rather than conventional transmission of data as electrons through wires, Professor Kuroda’s technique involves wireless beaming of data via radio waves between chip layers (a kind of RFID technology, already in wide use today). This method enables ultra-low power consumption and is ideally suited for long-term data storage (up to hundreds or even thousands of years), laying the foundation for “Digital Rosetta Stone” technology.

Successful observation of frequency comb at terahertz frequencies using coherent vibration of silicon atoms
Contributing to development of fundamental technology to enable 1000-fold improvement of the speed of optical communications.

  • As part of the PRESTO Strategic Basic Research Program, Associate Professor HASE Muneaki (University of Tsukuba) and Professor KATSURAGAWA Masayuki (University of Electro-Communications) have successfully developed fundamental technology for manipulating coherent vibration of atoms (lattice vibrations: phonons), at the extremely high frequency range of 100 terahertz (THz=1012 Hz). The researchers observed the generation of a frequency comb (an optical spectrum consisting of discrete elements equally spaced, like the teeth of a comb) based on a completely new principle: harnessing the coherent atomic motion of a silicon crystalline lattice at its highest mechanical frequency.
