This paper proposes a mathematical model of impact force generated by collision between landing foot and ground, by which a dynamic analysis and a supplementation of existing stability criteria are made. By using the proposed dynamic analysis, an energy-optimized gaital algorithm is proposed. To prove the effectiveness of the algorithm, simulation results are shown compared to the result of previous gaital algorithm.

In this paper, we introduce a case study of developing a miniature humanoid robot that has 16 degrees of freedom and is able to perform statically stable walking. The developed humanoid robot is 37cm tall and weighs 1,200g. RC servo motors are used as actuators. The robot can walk forward and turn to any direction on even surface. It equipped with a small digital camera, so it can transmit vision data to a remote host computer via wireless modem. The robot can be operated in two modes; One is a remote-controlled mode, in which the robot behaves according to the command given by a human operator through the user-interface program running on a remote host computer, the other is a stand-alone mode, in which the robot behaves autonomously according to the pre-programmed strategy. The user-interface program also contains a robot graphic simulator that is used to produce and verify the robot's gait motion. In our walking algorithm, the ankle joint is mainly used lot balancing the robot. The experimental results shows that the developed robot can perform statically stable walking on even surface.

인간의 걸음걸이를 보고 느끼는 감성적 반응에는 모든 사람들이 공감할 수 있는 '규칙성'이 있다. 본 논문은 이러한 규칙성을 수량적으로 추출하고 재구성하여 3D 캐릭터 행동제어에 적용하고자 하는 연구과정의 일부분이다. <"가"라는 감성반응을 가지고 있는 걸음걸이 "A"와 "나" 라는 감성반응을 가진 걸음걸이 "B" 의 신체적 수치 데이터를 임의의 비율로 섞었을 때, 그에 대한 감성반응 역시 "가"와 "나" 가 섞인 "가/나"가 된다.>란 가설을 증명해서 향후 연구의 타당성을 확보하는 것이 이번 논문의 목적이다. 3D Studio Max의 스크립트로 만든 EAM을 이용하여, 바이페드 형식의 2개의 걸음걸이 샘플을 브랜딩 하였다. 6번 중 4번의 실험에서 성공적인 브랜딩 결과물을 추출할 수 있었다. 이것은 모션캡처 등을 이용하지 않더라도 기본적인 바이페드 데이터만 있다면 다양한 걸음걸이의 바이페드를 생산할 수 있다는 것을 의미한다. 현재 팔, 다리의 1Cycle 운동조건이 갖추어진 바이페드 샘플을 대상으로 하고 있지만, 완성된 시스템을 위해서는 다양한 운동조건에서도 브랜딩이 가능한 툴이 필요하다.
