Analyzing Breathing Patterns in the Breaststroke Technique Through Dual-Media Kinematics and Fractal Dimension

Sensors
The most hydrodynamic swimming position occurs with the head submerged, highlighting the benefit of reduced breathing frequency for efficiency. This study aimed to characterize and compare kinematics between two breaststroke breathing patterns—breathing ...

Solution for the Direct Kinematics Problem of the General Stewart-Gough Platform by Using only Linear Actuators’ Orientations

, 2018
In this paper, we present a solution for the direct kinematics problem of the general Stewart-Gough platform where only the orientations of the linear actuators are measured with accelerometer sensors.

Identifying Physical Interactions in Contact‐Based Robot Manipulation for Learning from Demonstration

Advanced Robotics Research, EarlyView.
Robots can learn manipulation tasks from human demonstrations. This work proposes a versatile method to identify the physical interactions that occur in a demonstration, such as sequences of different contacts and interactions with mechanical constraints.

A Spatial Five-Bar Linkage as a Tilting Joint of the Breeding Blanket Transporter for the Remote Maintenance of EU DEMO

Machines
The future fusion power plant EU DEMO will generate its own tritium fuel through the use of segmented breeding blankets (BBs), which must be replaced from time to time due to material damage caused by high-energy neutrons from the plasma.

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

Advanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Increased loading of the lateral knee compartment in the unamputated knee during gait in people with unilateral transfemoral/through-knee amputations

Bone & Joint Research
Aims: People with unilateral transfemoral/through-knee amputations (UTF) are at risk of mechanically mediated contralateral knee osteoarthritis (OA). This study aims to identify the mechanical indicators of the development and progression of unamputated ...

Kinematics analysis of morphing process in multi-module robot systems

, 2010
The multi-module robot systems consist of a set of homogeneous modules. In the paper, seven connecting types of cuboid modules are analyzed. For deriving the transformation matrix of each connecting type, the concepts of basic group are proposed.

Asymmetry in Skipping Enhances Viability Against Control Input Noise

Advanced Robotics Research, EarlyView.
Quadruped animals use asymmetric galloping gaits at high speeds, yet the functional role of this asymmetry remains unclear. This study shows that left–right asymmetry in touchdown angles enhances robustness to control noise. Using a simple two‐legged locomotion model and viability theory, it demonstrates that asymmetric skipping substantially enlarges ...
