The role of QR Code robots in smart logistics is great. Cognitive robots, such as logistics robots, were mostly used to adjust routes and search for peripheral sensors, cameras, and recognition signs attached to walls. However, recently, the ease of making QR Codes and the convenience of producing and attaching a lot of information within QR Codes have been raised, and many of these reasons have made QR Codes recognizable as visions and others. In addition, there have been cases in developed countries and Korea that control several of these robots at the same time and operate logistics factories smartly. This representative case is the KIVA robot in Amazon. KIVA robots are only operated inside Amazon, but information about them is not exposed to the outside world, so a variety of similar robots are developed and operated in several places around the world. They are applied in various fields such as education, medical, silver, military, parking, construction, marine, and agriculture, creating a variety of application robots. In this work, we are developing a robot that can recognize its current position, move and control in the directed direction through two-dimensional QR codes with the same horizontal and vertical sides, and the error is to create a QR Code robot with accuracy to reach within 3mm. This paper focuses on the QR Code recognition mobile robotics study during the development of QR Code-aware indoor mobility robots.

본 연구는 광전환필름에 의해 변형된 태양광 하에서 채소류의 묘소질과 광합성 특성에 미치는 영향을 구명하기위해 수행 되었다. 상추와 배추, 오이 종자를 원예용 상토로 충진된 50구 플러그 트레이에 파종하고, 광전환 필름(SCF)과 상업용 폴리 에틸렌 필름(대조군) 하에서 재배하였다. 대조군 대비 SCF에 투과된 태양광 스펙트럼은 청-녹색광은 감소하고, 적색광은 증가했으며 R/FR 비와 R/B 비가 증가하여 묘의 광합성과 생육, 형태형성 측면에서 영향을 미치기에 충분한 수준이었다. 광합성속도는 SCF 하에서 자란 배추와 오이 묘에서 유의적으 로 증가했으며, 최대 광합성속도는 각각 23%, 19% 높게 나타 났다. 상추의 경우, SCF 처리구에서 생육이 유의적으로 감소 하였으며 도장하였다. SCF 필름 하에서 자란 배추의 경우, 형태적인 차이는 없었으나 잎의 건물중이 증가하여 묘의 충실도가 유의적으로 증가했고 왜화율은 10%로 나타났다. SCF 처리구의 오이 묘는 생육에 차이는 없었으나 엽병 및 초장이 유의적으로 감소하여 왜화율이 24%로 높게 나타났다. 결론적 으로 SCF에 의해 변형된 태양광 스펙트럼은 배추와 오이 묘의 광합성 효율을 증가시키고 묘소질을 향상시켰다고 판단되었다.

작물의 생체중을 추정하기 위해 다양한 연구가 시도되었지만, 이미지를 활용하여 생체중을 추정한 예는 없었다. 최근 합성곱 신경망을 사용한 이미지 처리 연구가 늘고 있으며, 합성곱 신경망은 미가공 데이터를 그대로 사용할 수 있다. 본 연구에서는 합성곱 신경망을 이용하여 미가공 데이터 상태인 특정 시점의 파프리카 이미지를 입력으로 작물의 생체중을 추정하도록 학습하였다. 실험은 파프리카(Capsicum annuum L.)를 재배하는 온실에서 수행하였다. 합성곱 신경망의 출력값인 생체중은 파괴조사를 통해 수집한 데이터를 기반으로 회귀 분석하였다. 학습된 합성곱 신경망의 결정 계수(R2)의 최고값은 0.95로 나타났다. 생체중 추정값은 실제 측정값과 매우 유사한 경향성을 보여주었다.

The calculation of the optimal trajectory of the stepped top-down robot was made using a genetic algorithm and a computational torque controller. First, the total energy efficiency was minimized using the Red-Cold Generic Algorithm (RCGA) consisting of reproductive, cross, and mutation. The reproducibility condition related to the position assembly of the start and end of the stride and the joints, angles, and angular velocities are linear constraints. Next, the unequal constraint accompanies the condition for preventing the collision of the swing leg at the corner with the outer surface of the stairs, the condition of the knee joint for preventing kinematic peculiarity, and the condition of no moment in safety in the traveling direction. Finally, the angular trajectory of each joint is defined by fourth-order polynomial whose coefficient is to approximate chromosomes. This is to approximate walking. In this study, the energy efficiency of the optimal trajectory was analyzed by computer simulation through a biped robot with seven degrees of freedom composed of seven links.

작물의 일중 광합성량을 정확하게 추정하기 위해서는 일중 태양의 위치 변화에 따른 작물의 정확한 수광량 변화를 정확하게 예측해야 한다. 그러나, 이는 많은 시 간, 비용, 노력이 소요되며, 측정의 어려움이 수반된다. 현재까지 다양한 모델링 기법이 적용되었으나 기존 방식으로는 정확한 수광 예측이 어려웠다. 본 연구의 목적은 파프리카의 3차원 스캔 모델과 광학 시뮬레이션을 이용하여 일중 시간 별 캐노피 수광 분포와 광합성 속도의 변화를 예측하는 것이다. 휴대용 3차원 스캐너를 이용하여 온실에서 재배되는 파프리카의 구조 모델을 구축하였 다. 주변 개체의 유무에 따른 캐노피 수광 분포의 변화를 보기 위하여 작물 모델 별 간격을 60cm로 1×1, 9×9 정 방형 배치하여 광학 시뮬레이션을 수행하였다. 광합성 속 도는 직각쌍곡선 모델을 이용하여 계산하였다. 3차원 파 프리카 모델 표면의 수광 분포는 오전 9시, 정오, 오후 3 시의 태양 각도에 따라 서로 다른 양상을 보였다. 캐노피 총 수광량은 9×9 배치로 주변 개체 수가 늘어남에 따라 감소하였고, 태양 고도가 가장 높은 정오에서의 감소율이 가장 적었다. 캐노피 광합성 속도와 CO2 소모량 역시 수 광량과 비슷한 양상을 보였으나 작물 상단부 엽의 광합 성 속도 포화로 인해 수광량 변화에 비해 적은 감소율을 보였다. 본 연구에서는 파프리카의 3차원 스캔 모델과 광 학 시뮬레이션을 이용하여 가상 환경 조건에서의 캐노피 수광과 광합성 분포를 분석할 수 있었으며, 이는 추후 다 양한 재배 조건에서 작물 수광량과 광합성 속도를 예측 하는 데에 효과적으로 활용될 수 있을 것으로 사료된다.
