  • There have been worldwide research and development efforts to automate various processes of bio-production and those efforts will be expanded with priority given to tasks which require high intensive labor or produce high value-added product and tasks under hostile environment. In the field of bio-production capabilities of the versatility and robustness of automated system have been major bottlenecks along with economical efficiency. This paper introduces a new concept of automation based on tole-operation, which can provide solutions to overcome inherent difficulties in automating bio-production processes. Operator(farmer), computer, and automatic machinery share their roles utilizing their maximum merits to accomplish given tasks successfully. Among processes of greenhouse watermelon cultivation tasks such as pruning, watering, pesticide application, and harvest with loading were chosen based on the required labor intensiveness and functional similarities to realize the proposed concept. The developed system was composed of 5 major hardware modules such as wireless remote monitoring and task control module, wireless remote image acquisition and data transmission module, gantry system equipped with 4 d.o.f. Cartesian type robotic manipulator, exchangeable modular type end-effectors, and guided watermelon loading and storage module. The system was operated through the graphic user interface using touch screen monitor and wireless data communication among operator, computer, and machine. The proposed system showed practical and feasible way of automation in the field of volatile bio-production process.

  • As the low labor-productivity is being floated up to be the most limiting factor in barley cropping, the endeavor of many researchers concerned have been concentrated on recovering from that. For this reason, in this experiment 8 kinds of sowing methods were employed to survey the yield productivity and the labor-requirement of each methods. And with promising the possibility of consistent mechanization, both prediction of the assurable requirement of labor investment and calculation of the labor productivity in each method were estimated so that the possibility of labor-saving in barley cultivation investigated. Also sowing methods for labor-saving cultivation were presented according to the labor-structure of farm as divided with the phases.

  • Recently, interests in the research and development of labor-saving mechanization for upland field agriculture have increased. In reality, each farming operation is solely mechanized, so it does not contribute to promote labor-saving rate in upland agriculture. Therefore, the objective of this study is to evaluate labor-saving efficiency through field capacity and cost analyses for the developed an integrated tractor implement for upland field farming. The theoretical working time of the integrated implement including five modules is 0.56 hr/10a, reducing 67% of working time comparing with that of conventional individual farming process. Effective field capacity is 0.09 ha/hr, which is 2.95 times better than conventional practices and the arable area is evaluated to be 9.07 ha. In the cost analysis, the initial purchase cost is estimated to be reduced by 43%, and the cost per unit time(hour) and the cost per unit area(10a) were reduced 68% and 58%, respectively. Therefore, a sequential field work using the integrated tractor implement would contribute considerably to the labor-saving in the upland farming.
