최근 스크린 골프와 같이 실내에서 가상현실과 결합하여 운동을 즐길 수 있는 다양한 시도가 이루어지고 있다. 승마는 비싼 경제적 비용 외에도 승마기술의 습득이 쉽지 않고 위험한 운동으로 대중화 보급에 어려움을 겪고 있다. 본 연구에서는 병렬 로봇 기구에 기반한 승마로봇 플랫폼을 개발하고 가상현실과 결합하여 실제와 유사한 승마감을 체험할 수 있도록 하였다. 전문가의 승마자세를 기반으로 일반 승마자의 체위를 교정할 수 있도록 비전센서를 탑재하여 모션 캡처 처리를 하였으며 말의 보법에 기반하여 승마 난이도를 체험할 수 있도록 하였다. 개발된 승마로봇을 이용하면 전천후로 승마를 즐길 수 있으며 체계적인 승마교육에도 사용될 수 있어 승마 스포츠의 확산을 위해 널리 사용될 수 있다.

We develope a riding robot system named as "RideBot" for health-care and entertainments. An algorithm for estimating riding position and volition is proposed by using bio-signals. We analyze the riding position and volition in real-horse riding environments and build up the database. With this database and sensor informations, standard positions are made. For the volition estimation, we use the acceleration and deceleration sensor information and bridle information for direction change. We propose a hybrid control algorithm in which discrete-state and continuous-state controls are combined. The efficiency of the proposed algorithm is evaluated thru various experiments.

This paper describe the riding robot system named by "RideBot" which is a riding robot like as a horse. In order to simulate the riding motions, we develope the saddle mechanism which can generate 3 DOF motions including pitch, roll, and bounce movement, and also we controlled the riding motions and the intention of horseman. To generate the riding motions with the bodily sensation, we developed Novel Washout Filter and the algorithms for motion control. And also, we developed some health care service for the health care of horseman. A body state index was proposed that evaluates the personal health state from both the measured physiological variables and the surveyed questions. The physiological variables such as weight, blood pressure, heart rate variability (HRV), accelerated state photoplethysmograph(APG), body fat, and happiness index were measured by the specially designed bio-handle system and survey questions. The efficiency of the proposed ride robot is evaluated in the experiments.

This paper analyzes the motion of a horseback riding robot which has two actuators and three joints. It is impossible to control the saddle to get to any position and orientation using the two motors because the robot has less degrees of freedom than the number of joints. Therefore it is required to know the possible location and orientation along with the velocity characteristics of each pose prior to motion planning. For this purpose, this paper analyzes the characteristics of the robot motion. The authors derive the forward and inverse kinematics of the robot motion and developed the trajectory editor for motion planning. Also, Jacobian of the robot is analyzed. It reveals that one of the actuator has little influence to the speed of the saddle motion while the other affects the speed of the saddle motion dominantly. The approach of the paper can be applied for the analysis of characteristics of a robot which has less number of actuators than that of joints.

Horse riding is widely recognized as a valuable form of education, exercise and therapy. But, the injuries observed in horse riding range from very minor injuries to fatalities. In order to reduce these injuries, the effective horseback riding simulator is required. In this paper, we proposed the implementation method of horse gait and riding aids for horseback riding robot simulator HRB-1. For implementation of horse gait to robot simulator, we gathered and modified real motion data of horse. We obtained two main frequencies of each gait by frequency analysis, and then simple sinusoidal functions are acquired by genetic algorithm. In addition, we developed riding aids system including hands, leg, and seat aids. With the help of a developed robotic system, beginners can learn the skill of real horse riding without the risk of injury.

기존의 스포츠 시뮬레이터 제품들은 모션 플랫폼의 운동과 간단한 시각적 콘텐츠를 이용한 실감 표현에 집중되어 있고 놀이위주의 적용에 국한되어 있어, 사용자가 체감할 수 있는 오감 자극효과가 낮아 고실감 적용에는 부족하며, 전문 콘텐츠 부재로 인해 교육용 스포츠 시뮬레이터로서의 적용은 아직 어렵다. 본 연구에서는 다종목 교환이 가능한 다축 공통 플랫폼과 교환식 스포츠 모듈로 분리하여 공통 플랫폼의 운동 자유도를 4자유도(Surge, Sway, Heave, Yaw) 운동을 할 수 있도록 스포츠 플랫폼을 설계하였다. 이 플랫폼은 안정성을 보장하고 간섭을 최소화하는 데 목적이 있다. 이 플랫폼에 탑재되는 교환식 스포츠 모듈의 운동 자유도는 2자유도(Roll, Pitch)로 승마, 요트와 같은 다양한 운동이 적용이 가능하고, 독립적인 회전 2자유도의 체감형 시뮬레이터의 구현이 가능하도록 하였다.

In this research, a riding robot system named as "RideBot" is developed for health-care and entertainments. The developed riding robot can follow the intention of horseman and can simulate the motion of horse. The riding robot mechanisms are used for many functions of attitude detection, motion sensing, recognition, common interface and motion-generations. This riding robot can react on health conditions, bio-signals and intention informations of user. One of the objectives of this research is that the riding robot could catch user motion and operate spontaneous movements. In this paper, we develope the saddle mechanism which can generate 3 degrees-of-freedom riding motion based on the intention of horseman. Also, we develope reins and spur mechanism for the recognition of the horseman's intention estimation and the bio-signal monitoring system for the health care function of a horseman. In order to evaluate the performance of the riding robot system, we tested several riding motions including slow and normal step motion, left and right turn motion.
