With the decrease in the number of workers in the domestic agricultural population and the rapid aging of the population, the need for technology that minimizes the risk of disease and enables efficient work is emerging in agricultural sites. Robot technologies and devices for preventing and treating diseases of workers or patients are being developed in industrial and medical fields, but there is a limit to their application to agricultural work in which atypical work is mixed. In addition, considering that most of the agricultural population is elderly and female, it is essential to develop wearable suits that can experience muscle assistance effects with comfortable fit in various movements. In this paper, we developed a wearable suit system that considers wearability and weight as a muscle strength aid. And in order to evaluate the characteristics of the developed product, the performance is verified by measuring the degree of muscle fatigue through EMG tests.

Because there are few constraints on the structure design of a product in manufacturing, additive manufacturing technology aids to the simplification of many manufacturing processes in numerous industries. In instance, as compared to traditional cutting, casting, and clay modeling, it is able to produce prototype models relatively rapidly and simply. This is especially useful when employing additive manufacturing technologies to create robots or wearable platforms with complex shapes and many considerations. This article presents an application case for a wired power transmission type wearable suit system for a single actuator, with the assumption that it will be created using additive manufacturing technology to address issues with existing agricultural wearable robots.

We developed a platform that was capable of autonomous steering in a furrow environment. It was developed to autonomously control steering by recognizing the furrow using a laser distance, three-axis tilt, and temperature sensor. The performance evaluation indicated that the autonomous steering success rate was 99.17%, and it was possible to climb up to 5° on the slope. The usage time was approximately 40 h, and the maximum speed was 6.7 ㎞/h.
