In this study, we propose a peristaltic flexible transfer system for transferring feces in a free piping route. Currently, human feces is incinerated and disposed in space, such as on the International Space Station. As feces contain a large amount of reusable organic matter and water, the ability t…
This study proposed a peristaltic motion-type inspection robot equipped with a "linear antagonistic mechanism using artificial muscles with an endoskeletal structure" to amplify propulsion and traction. We sought to develop an in-pipe inspection robot for long, narrow, and complex pipes requiring la…
The cleaning of residential ventilation ducts is necessary to prevent damage to health. However, since residential ventilation ducts are usually thin and curved, cleaning them is difficult. It is also difficult to obtain thrust within the duct using a wheel or a snake type robot because it is hard t…
Sub-seafloor exploration is an important area of biological and geological research, and often requires samples of seafloor mud to be recovered. The minerals and marine sediments trapped in this mud are also potentially valuable resources. However, seabed exploration has been limited by the complexi…
Sewer pipes play an important role in a city's infrastructure. However, accidents have occurred in recent years due to increasingly old pipes. To prevent such accidents, there is a need to check the internal condition of pipes. Therefore, we focused on the locomotion of a robotic earthworm that is c…
Sub-seafloor explorations are important for biological and geological research. Sampling mud is one of the major sub-seafloor exploration procedures. The mud-including mineral resources and marine sediments are potentially valuable resources for future studies. Therefore, we propose a peristaltic-cr…
In recent years, the demand for rocket launching has increased due to the development of space technology. However, using inexpensive rockets is not always possible. Although the cost of solid-propellant rockets is relatively reasonable, safely manufacturing a large amount of solid propellant is dif…
