This paper proposes a reactive motion controller for a humanoid robot to maintain balance against a large disturbance, by relatively stepping. A reactive step is performed by the robot, so that it reduces the disturbance force. Several problems are addressed: first the motion is designed to ensure the respect of stepping constraints such as a dynamical stability, motion feasibility of the swing leg...
This paper presents preliminary results on generating walking and turning motion of a humanoid robot based on human motion data obtained by using motion capturing system. The target humanoid robot is recently released HRP-4C, which looks like a Japanese woman with realistic geometry. One of the main uses of this robot is to be entertainment. Therefore it is important that the robot's motions are easily...
In order to help with care work and rescue operations, humanoid robots should have the ability to lift and carry humans gently and steadily. This paper is a step towards the ultimate goal of giving humanoid robots the ability to lift and carry humans, a task which involves very complex physical interactions. We measure several such lifting and carrying motions using a motion capture system, paying...
In this paper, we generate the biped gait of a humanoid robot that looks like a human's one. To generate the human like motion, we first capture walking motion of a human. Then, we analyze the captured data and obtain several information such as the relationship between the step length and waist height etc. We consider applying these informations to the real humanoid robot. Also, when the human walks,...
It is a difficult task to create a realistic human animation because of the high complexity of human motion. To address this problem, a new method is presented for producing physically valid motion with example motions. The core of our method is physics-based space-time optimization (PBSO). PBSO introduces physical constraints into conventional space-time optimization and then ensure the physical...
Recent humanoid control investigations have emphasized the importance of controlling whole-body angular momentum throughout a movement task. For typical movement tasks, such as normal walking, such controllers minimize fluctuations in angular momentum about the center of mass (CM). This minimization is consistent with observed behavior of humans for such tasks. However, there are cases where such...
In this paper, a method that makes biped robots track zero-moment-point (ZMP) reference trajectories is proposed. The biped robots have flat rectangular soles with force sensors at each corner. The sensors detect reaction force from the ground. Sensor information is transformed into useful structure, which is defined as ldquoenvironmental modes.rdquo The environmental modes represent contact states...
Biped robot research has been developing several decade of year in the world. We usually saw experimental biped robot in order to reduce single leg support time and let biped robot easy to control, so many researcher choose linearism plant of biped robot. But this approach couldnpsilat make our biped robot smooth walking naturally like as real human. We will obtain each angle of joints from real human...
