In this paper, a marionette control system using wrist and finger gestures through an IMU sensor is studied. The signals from the sensor device are conditioned and recognized, then the commands are sent to the 8 motors of the marionette via Bluetooth (5 motors control the motion of the marionette, and 3 motors control the location of the marionette). It is revealed that the degree of freedom of fingers are not independent from each other, therefore, some gestures are hardly made. Gesture mode changes for difficult postures of the fingers in cases of a lack of finger DOF are proposed. Therefore, the gesture mode change switches the assignment of gesture as required. Experimental results show that gesture mode change is successful for appropriate postures of a marionette.

There have been many experiments and researches of virtual marionettes which mostly focused on controlling the marionettes more delicately and precisely. This paper will prove that performances using virtual marionettes can show more than simply controlling other objects delicately and precisely. The performance that this paper is discussing about used not only a virtual marionette but also an actual marionette. In this performance, a human manipulated an actual marionette and the actual marionette controlled a virtual marionette. This performance is meant to represent a controlling relationship between an actual world and a virtual world. This recursive and duplicate process will show that experiments using virtual marionettes can express more diverse objectives than existing experiments.

A marionette is a moving puppet that can be made to perform several actions by pulling wires connected to the puppet. Because a marionette is operated by hand, a stage performance with a human-sized marionette is impossible. However, a marionette robot operated using a wire controller could be used as a human-sized marionette to conduct a stage performance with other robots or actors. In addition, by using mobile stages that utilize mobile platforms, a wire controller, and the marionette robot body, the large marionette robot system designed in this study can be made to rotate and translate freely in a stage performance. The feasibility of the structure of the marionette robot wire control system is verified by using dynamics analysis. Furthermore, the efficiency and safety of the robot is demonstrated by manufacturing and operating a prototype robot.

A doll created by various materials is a miniature based on human model, and it has been one of components in a puppet show to take some responsibility for human's culture activity. However, demand and supply keeps on the decrease in the puppet show industry, since professional puppeteer has been reduced rapidly, and also it is difficult to initiate into the skill. Therefore, many studies related Robotic Marionette for automation of puppet show have been internationally accompanied, and more efficient structure design and process development are required for better movement and express of puppet with motor based controller. In this research, we suggest the effective way to enable to express the marionette's motion using motion data based on motion capture and 3D graphic program, and through applying of 3D motion data and proposal of simulation process, it will be useful to save time and expenses when the Robotic Marionette System is practically built.

Marionette controlling robot has a problem that generates interference in rotation and intersection, therefore, the research on the independent shifter to move freely on the stage is required. Connecting omni-directional mobile robot with marionette controlling robot can solve this problem. Omni-directional mobile robot makes itself rotate and translate in 2D plane freely. Magnetic device is used to connect the moving part with the control part of the robot to minimize the intereference generated by the movement of robot. When robot moves, it can move to all directions with the suitalbe setting of banlance power. The moment of inertia is minimized by dividing the robot to the upper and lower parts in the marionette performance stage. Rotation and interference problem of independent omni-wheel Robot can be solved by using the permanent magnet. The efficiency and safety of the marionette controlling robot is proved by the experiment.

We are concerned with the dual-arm manipulation for disaster-responding special-purpose machinery. This paper presents a control strategy for performing complex work in an irregular environment, the control algorithm, the hydraulic circuit, and the master devices. The occurrence of collapse accidents at disaster sites such as natural disasters and building collapses is increasing, which is emerging as a social problem. In particular, for the initial response, various tasks must be performed in an irregular environment. The Marionette algorithm for intuitive control of 'as if the operator's arm is moving' was presented as a control strategy for dual-arm manipulators with attachments and the prototype. Next, the hydraulic circuit, control system, and wearable-type master device presented to implement the Marionette algorithm were explained and verified through an experiment in which rebar-cutting, drum-lifting, and lifting a bottle with one arm and pouring the water into the bucket with the other arm were tested.

마리오네트는 끝단에 연결된 줄을 이용하여 사용자가 제어 할 수 있는 인형이다. 본 연구는 마리오네트 원리를 적용하여 인간의 동작을 통해 로봇을 직접 제어할 수 있는 방법을 제안한다. 이를 위해 인간 손과 로봇 손의 사이에 가상의 줄(Virtual Elastic strip)이 연결되어 있는 모델을 사용한다. 실시간으로 측정되는 인간의 동작에 따라 가상 줄의 길이가 변하게 되고 가상 힘이 발생된다. 이 가상 힘을 고려하여 로봇 팔의 정동역학(Forward dynamics) 해를 구한 후, 제어를 위한 로봇의 각 관절값을 얻게 된다. 제안한 방법을 이용하여 인간 동작을 실시간으로 가상 로봇의 동작으로 변환하고 제어하는 실험을 수행하였다.

인터랙티브 컴퓨터 게임과 컴퓨터 애니메이션에서, 유관절체의 움직임을 직관적으로 제어하도록 하는 것은 어려운 문제로 인식되고 있다. 이런 분야에서는 대부분 움직임의 대상이 되는 캐릭터가 많은 관절로 연결되어 있는데, 이때 각 관절을 사용자의 의도대로 쉽게 조종할 수 있도록 해주는 인터페이스를 디자인하기가 어렵기 때문이다. 본 논문에서는 자유도(DOF)가 높은 캐릭터의 움직임을 제어하기 위해 오랫동안 인형극에서 사용되고 있는 마리오넷 조종 기법[5]을 응용한 마리오넷 시스템을 제안하고자 한다. 우리는 가상 마리오넷 시스템을 물리기반 모델링과 햅틱 인터페이스를 기반으로 구현하였고, 이 시스템을 통해 높은 자유도를 가지는 유관절체 캐릭터의 복잡한 움직임을 쉽게 생성해낼 수 있었다. 그리고 사용자에게 햅틱 포스 피드백을 줌으로써 더욱 정교한 마리오넷을 조작이 가능하도록 하였다. 이 시스템을 일반적인 유관절체에 적용한다면 다양한 움직임을 쉽고 빠르게 생성할 수 있을 것이다.
