In food industry, shortage of workers is a serious problem. Automation of food handling is a critical nowadays. To alleviate the damage during food picking by robotic hand, we propose non-contact acoustic impedance estimation with ultrasonic wave. We have the assumption of the correlation between hardness and acoustic impedance, and, built up ultrasonic transmission model considering attenuation by reflection and absorption, then, made an experiment to estimate the impedance. As the result, we succeeded in detecting acoustic impedance without contact.

In the future estimation of 2050, the food demand increases 70% and the production decreases 15% caused by global warming, and farmer population be 1/5 of current workers. Until 2050, we need an agricultural system of twice production with the same farmland area and 5 times effective operations. To realize the sustainable society, smart agriculture including robot technology, AI, IoT is one of the solutions for food issues. We have been working for a greenhouse project under enPiT-everi for implementation of robotic, AI and IoT technologies to agriculture. In this paper, we introduce the project and robotic applications.

Development of a Handy Autonomous Underwater Vehicle"Kyubic" Reviewed International journal

Matsumura Toshimune, Uemura Yuuichiro, Yanagise Kentaro, Tanaka Yoshiki, Nishida Yuya, Ishii Kazuo

Proceedings of International Conference on Artificial Life and Robotics ( ALife Robotics Corporation Ltd. ) 26 405 - 408 2021.01

Authorship：Corresponding author Language：English Publishing type：Research paper (international conference proceedings)

Ocean is one of big challenging and extreme environments, and hard for human to access directly. As the tool for ocean survey, Autonomous Underwater Vehicles: AUVs are expected and developed from ‘80s. The recent rapid progress of computer and information technologies makes the development of AUVs easier and more practical. We had developed a handy AUV "Kyubic" for the observation of shallow water and artificial structures. In this paper, we describe the system architecture of Kyubic and the experimental results in Underwater Robotics Competition in Okinawa 2020.

Marine resource survey by an underwater vehicle is expected. To realize cheap self-positioning for the underwater vehicle, we have been developing on the acoustic positioning system which is low cost and easy to maintain. The acoustic positioning system has four hydrophones which consists of molding commercially available MEMS micro phones with pressure-resistant resin, an audio device, and a micro controller. To evaluate the system, positioning experiments was performed in the small tank. In the experiments, the system detected delay time among four hydrophones, however its positioning was not good accuracy. In the future, we will improve the accuracy of positioning by interpolating data and considering the effect of baseline.

Most of the conventional hydrophones (underwater microphones) use PZT ceramic as the material, and there are problems such as variation in sensitivity, the necessity of high-magnitude amplification and high cost.We developed and evaluated a low-cost, easy-to-use MEMS hydrophone that is waterproof and pressure-resistant while maintaining the bandwidth of a commercially available MEMS microphone.
