Design, Modeling, and Experimentation of Polar Robot: Assisted Sail and Multimode Motion for Energy Saving

Advanced Intelligent Systems, Volume 7, Issue 12, December 2025.
This article proposes a polar robot that utilizes assisted sail and multimode motion to achieve energy‐saving. The design, modeling, and experimental methods are introduced. The results show that the energy‐saving effect of the robot using a multimode energy savings control strategy reaches 21.19%, providing technical support for long‐term polar ...

Effects of an experimental in situ seabed disturbance on deep‐sea benthic ecosystem function and macro‐infaunal community structure on the Chatham Rise, Southwest Pacific

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1496-1529, December 2025.
ABSTRACT Expansion of extractive industries to deep‐sea environments will lead to increased stresses on seafloor ecosystems. We examined changes in environmental parameters following direct and indirect experimental benthic disturbance using a modified plough on the Chatham Rise (∼450 m water depth), Aotearoa/New Zealand. Measurements included sediment

A Similitude of an Unpowered Pneumatic Tire [PDF]

, 1968
When a farmer tills a field with a wheel-supported disc harrow or pulls a loaded wagon through a soft field, the speed and efficiency of his operation depend on the relationship between each tire and the soil.

Robotic Arm Geomechanical Experiments and Analyses to Enable Lunar Science and Settlement

Earth and Space Science, Volume 12, Issue 11, November 2025.
Abstract This study evaluates the capability of a robotic arm equipped with a force‐torque sensor and a specially designed scoop to perform geomechanical characterization of high‐fidelity lunar highlands regolith simulant. Experiments focused on pressure‐sinkage, shear strength, and angle of repose to assess the performance and applicability of the ...

A Study Demonstrating That Using Gravitational Offset to Prepare Extraterrestrial Mobility Missions Is Misleading

Journal of Field Robotics, Volume 42, Issue 7, Page 3772-3794, October 2025.
ABSTRACT Recently, there has been a surge of international interest in extraterrestrial exploration targeting the Moon, Mars, the moons of Mars, and various asteroids. This contribution discusses how current state‐of‐the‐art Earth‐based testing for designing rovers and landers for these missions currently leads to overly optimistic conclusions about ...

Numerical investigation of the behaviour and performance of ships advancing through restricted shallow waters [PDF]

, 2017
Upon entering shallow waters, ships experience a number of changes due to the hydrodynamic interaction between the hull and the seabed. Some of these changes are expressed in a pronounced increase in sinkage, trim and resistance.
