Modularis: Modular Underwater Robot for Rapid Development and Validation of Autonomous Systems
Autonomous underwater robots typically require higher cost and time for
demonstrations compared to other domains due to the complexity of the
environment. Due to the limited capacity and payload flexibility, it is
challenging to find off-the-shelf underwater robots that are affordable,
customizable, and subject to environmental variability. Custom-built underwater
robots may be necessary for specialized applications or missions, but the
process can be more costly and time-consuming than purchasing an off-the-shelf
autonomous underwater vehicle (AUV). To address these challenges, we propose a
modular underwater robot, Modularis, that can serve as an open-source testbed
system. Our proposed system expedites the testing of perception, planning, and
control algorithms.Comment: 7 pages, 13 figures, presented at OCEANS 202
System Design of an Autonomous Underwater Robot “DaryaBird”
Various kinds of robots have been developed parallel with the progress of computers and information processing technology, and the operations in the extreme environments, such as disaster areas, space and ocean, are getting one of the practical solutions for those hazardous missions. The underwater robots are one of the extreme environment robots and expected as one of solutions for underwater activities i.e., maintenance of underwater structures, observations, scientific research, where research area is getting wide and deep and also underwater structures are getting large-scale and deep-depth. Their efficiencies have been investigated during recent decades and are proven by ocean experiments. However, the robotic system including the support vessels is still big scale, and not so easy to handle by a few researchers. In this paper, we describe the design of an underwater robot “DaryaBird” developed aiming at handy, small underwater robots which can be operated by a few researchers. In addition, experimental results and mission strategies for AUVC 2010 are reported.AUVSI & ONR\u27s 13th AUVSI 2010 : Association for Unmanned Vehicle Systems International (AUVSI) North America 2010, Aug 24-27, 2010, Denver, CO., US
