| Outline of Research at the Start |
We propose Aerial-Terrestrial-Aquatic Robots (ATA-Robots) that are capable of search and rescue in an ATA Extreme Environment (specifically a flooded cave) extreme conditions such as zero visibility, strong disturbances from water/wind flow and strong waves at the water’s surface.
We will develop new concept of ATA Control, ATA Sensing and ATA Interface concept to enable robot to have seamless aerial-terrestrial-aquatic transition. The dataset will be collected at several cave in the world for training testing and optimization.

| Outline of Annual Research Achievements |
This year, we completed a major part of our project, focusing on ATA mapping. To estimate point clouds during aerial-aquatic transitions, we developed a new multi-box interpolation method. We based our proposed method on studying the noise characteristics of aerial and aquatic point clouds. We also developed an image processing technique to predict whether we should fuse point clouds or not. This allows the robot to avoid collisions during transitions. We mapped the environment using a thermal camera, which helps the robot to see in dark underwater areas by developed a machine learning-based panoptic perception-based generative adversarial network for thermal-to-color image translation.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
We have been able to advance the development of ATA mapping in Japan, specifically in several domestic caves. Despite the challenges posed by Covid-19, we were unable to conduct experiments abroad as planned. However, we have successfully conducted experiments in local caves in Japan and we hope to conduct experiments abroad by the end of this year.
|
| Strategy for Future Research Activity |
Our main focus this year is the development of the ATA control part for the ATA robot. Our goal is to design a robot that can adapt its leg to allow for smoother movement from aquatic to aerial environments. First, we will conduct simulations to verify the control algorithm. Later, we plan to test the robot in an indoor pool and eventually move on to an outdoor pool.
Additionally, we have a student who is interested in using a thermal camera in different scenarios. As a result, we are planning to improve ATA mapping by implementing an active water jet.
