본 프로젝트에서는 다양한 지형에 구애받지 않고 전천후로 활동할 수 있는 로봇을 구현하기 위해 바퀴형 로봇 보다는 4족 보행 로봇을 채택하여 지형 극복에 더 유리하고 안정적인 자세 제어와 보행을 할 수 있는 동시에 LiDAR 센서와 카메라 모듈을 이용한 SLAM(동시적 위치 추정 및 지도작성)과 원격으로 사물과 사람들을 파악할 수 있는 원격조종 탐사로봇을 개발하고자 한다.

In this paper ZMP was considered in order to get a walking stability, so the gait in the stable domain was realized through putting the stability margin in the sole domain of a foot. It is assumed that the robot's legs have 12 joints to operate a open-loop drive and there was no external disturbance under walking phases, additionally, the robot is walking on the flat plane. It was observed that the robot's walking trajectory, locus of COM and ZMP after imposing the motion to each joint. For realizing the simulation considering ZMP and movement of mass center, it was checked if it is stable for the constraint robot model to walk in stability and the feasibility was estimated about its dynamic gait. Eventually it was shown that a constraint gait algorithm is able to realize. To verify the proper walking process, ZMP(Zero Moment Point) theory is applied and the simulation has been done by ADAMS.

지능형 로봇은 인간 생활 환경에서 작동하고 일반 소비자를 대상으로 한다는 점에서 기존의 산업용 로봇과는 다른 내부 구조를 가져야 한다. 또한 표준화된 개방 구조를 갖추어 로봇 전용의 부품 산업이 활성화 될 수 있도록 하여 결과적으로 로봇의 단가를 낮출 수 있어야 한다. 본 고에서는 공장자동화와 자동차 분야에서 먼저 도입되고 있는 버스 형태의 제어 통신망이 지능형 로봇 분야에서 어떤 이점을 제공하는지에 대해 살펴보고, 최근의 2족 보행로봇에 성공적으로 적용되고 있는 대표적인 실시간 제어 통신망의 하나인 CAN에 대해 분석하고 CAN에 기반한 상위레벨 프로토콜을 소개한다.

We developed a human-sized BWR(biped walking robot) driven by a new actuator based on the ball screw which has high strength and high gear ratio. The robot overcomes the limit of the driving torque of conventional BWRs. Each leg of the robot is composed of three pitch joints and one roll joint. In all, a 10 degree-of-freedom robot with two balancing joints was developed. The BWR was developed to walk autonomously such that it is actuated by small torque motors and is boarded with DC battery and controllers. In the performance test, the BWR peformed nice motions of sitting-up and sitting-down. Through the test, we could find capability of high performance in biped-walking.

As the population of elderly people and disabled people are increased, various demands for human welfare using robot system are raised. Especially autonomous rehabilitation system using robot could reduce the human effort while maintaining the its intrinsic efficacy. This study deals with mobile gait rehabilitation system which combined with BWS (Body Weight Support) for training of elderly and handicapped people who suffer the muscle force weakness of lower extremity. BWS which is designed by kinematic analysis of body lifting characteristics and walking guide system are integrated with main control system and wheeled platform. This mobile platform is operated by UCS (User Command System) and autonomous trajectory planning algorithm. Finally, through the EMG (Electromyography) signal measuring and its analysis for subject, performance and feasibility of developed system is verified.

In this paper, the mechanism that can walk efficiently in wet land or sand area is proposed. A vision camera is attached to the mechanism, which makes a kind of biologically inspired robot for coast guard. This visionary information enables the biologically inspired robot to react in peripheral environment by a soft-computing algorithm. In addition, the biologically inspired robot can achieve the mission appointed by a programmer connecting with outside, based on RF and Blue-tooth communication module. Therefore, the purpose of this research is the implementation of the biologically inspired robot that can operate most adaptively in sand and wet surface based on Theo Jansen mechanism.
