  • DARPA carries out several R&D programs for hypersonic vehicles to maintain the U.S. military superiority in air and space. Falcon program is the core of the DARPA's activitiy for the hypersonics including the long-term step-by-step approach from HTV-1, HTV-2, HTV-3X to HCV. Hypersonic Turbo-Based Combined Cycle (TBCC) engine technologies research and development programs, HiSTED, FaCET and Vulcan, are also the parts of their activities. Present article presents the summarized review on the backgrounds, technologies and relationships of those programs.

  • This paper describes the design, development, and performance testing of an autonomous ground vehicle that was developed to participate in the DARPA Grand Challenge that was held in March 2004. The authors of this paper are members of Team CIMAR which was one of twenty five teams selected by DARPA to participate in a competition to develop an autonomous vehicle that can navigate from near Los Angeles to near Las Vegas at speeds averaging twenty miles per hour. Most of the event was held on open terrain and trails in a rocky desert environment. This paper describes the overall system design and the performance of the system at the event.

  • The humanoid robot, DRC-HUBO is developed from the KHR (KAIST Humanoid Robot) series to meet the requirements of the DARPA Robotics Challenge. DARPA Robotics Challenge was a competition to develop semi-autonomous humanoid robot so that dispatched in dangerous environments in place of humans like the Fukushima nuclear accident. In this paper, we introduce DRCH-UBO briefly and a methodology to remove debris blocking an entryway. The methodology includes inverse kinematics for DRC-HUBO and stabilization controller based on ZMP. Proposed inverse kinematics is robust, and pelvis-related tasks improve the manipulability and workspace of the arms. The controller improves the damping characteristic of the system and mitigates the instability during removal of debris. For given position and orientation of the debris, DRC-HUBO generates motion to reach the debris and lift up while stabilizing itself. Many experimental results verify our proposed methodology.

  • 최근 음성 정보처리, 특히 맨.머신 인터페이스로서의 음성입출력의 실현에 큰 기대가 모아 져서 각국에서 이에 관련된 연구가 국가규모 또는 국제간의 협력의 형태로 조직적으로 진행되고 있다. 이와 관련한 주요 연구계획들로는 - 프랑스의 GRECO 및 PRC project - 영국의 ALVEY program - 미국의 DARPA project - EC 여러나라간의 ESPRIT program 및 COST 2009 project - NATO의 주도에 의한 RSC 10 program - 일본의 ICOT project 및 ATR International의 자동번역전화 project등을 들수 있다. 본고는 일본음향학회 논문지 1986년 12월호에 게재된 K. Shikano 및 A. Kurematsu(ATR 자동번역전화연구소, 일본)의 동일제목의 해설 기사를 편역한 것으로서 연속음성인식 및 이해에 관한 각국의 연구동향을 정리한 것이다. 특히 DARPA의 연속음성인식 프로젝트를 중심으로한 미국의 연구동향 및 일본 ATR 자동번역전화연구소의 음성이해 시스팀에 대하여 자세히 소개 하고 있다.
