RL-Based Vibration-Aware Path Planning for Mobile Robots’ Health and Safety
Published on 2025-03-10 by Sathian Pookkuttath, Braulio Felix Gomez, Mohan Rajesh Elara @MDPI
Abstract: Mobile robots are widely used, with research focusing on autonomy and functionality. However, long-term deployment requires their health and safety to be ensured. Terrain-induced vibrations accelerate wear. Hence, self-awareness and optimal path selection, avoiding such terrain anomalies, is essential. This study proposes an RL-based vibration-aware path planning framework, incorporating terrain roughness level classification, a vibration cost map, and an optimized vibration-aware path planning [...]
Our summary: Validation through virtual and real-world experiments shows effective avoidance of rough areas while maintaining shortest distance compared to A* algorithm.

Effects of Unstable Exercise Using the Inertial Load of Water on Lower Extremity Kinematics and Center of Pressure During Stair Ambulation in Middle-Aged Women with Degenerative Knee Arthritis
Published on 2025-03-10 by Yuanyan Huang, Shuho Kang, Ilbong Park @MDPI
Abstract: Stair ambulation requires precise lower extremity control and postural stability. Middle-aged women with degenerative knee arthritis (DKA) are at an increased risk of falls, yet the effects of unstable load training on their postural stability remain underexplored. This study investigated the effects of a 10-week Aqua Vest-based unstable load training program on postural stability and pain during stair ambulation in middle-aged women with DKA. Thirty participants were randomly assigned to an exe[...]
Our summary: Effects of Aqua Vest-based unstable load training on postural stability and pain during stair ambulation in middle-aged women with DKA. Participants showed significant improvements in spatiotemporal and kinematic parameters, reduced pain levels, and enhanced postural stability.

Application of Cloud Simulation Techniques for Robotic Software Validation
Published on 2025-03-09 by Diogo Vieira, Miguel Oliveira, Rafael Arrais, Pedro Melo @MDPI
Abstract: Continuous Integration and Continuous Deployment are known methodologies for software development that increase the overall quality of the development process. Several robotic software repositories make use of CI/CD tools as an aid to development. However, very few CI pipelines take advantage of using cloud computing to run simulations. Here, a CI pipeline is proposed that takes advantage of such features, applied to the development of ATOM, a ROS-based application capable of carrying out the ca[...]
Our summary: Application of Cloud Simulation Techniques for Robotic Software Validation. Proposed CI pipeline utilizing cloud computing for simulations in the development of ATOM, a ROS-based application. Utilizes GitHub Actions, AWS RoboMaker, Rigel, and Codacy for static analysis and unit testing. Valuable tool for ATOM development and blueprint for similar pipelines in robotic systems.

Effect of Vertical Ground Reaction Force Biofeedback on Knee and Hip Neuromechanical Characteristics During Walking in Older Adults
Published on 2025-03-09 by Forouzan Foroughi, Soroosh Sadeh, Hao-Yuan Hsiao @MDPI
Abstract: This study aimed to assess the effect of real-time vertical ground reaction force (VGRF) biofeedback on sagittal plane hip and knee joint biomechanics and extensor muscle activities in older adults. Fifteen healthy older adults (71 ± 5.8 years) walked on a treadmill while instructed to increase their first peak of VGRF via biofeedback. Whole-body kinetic and kinematic data and electromyography data for the vastus lateralis and gluteus maximus muscles were recorded. A one-way repea[...]
Our summary: This study investigates the impact of real-time vertical ground reaction force biofeedback on knee and hip biomechanics in older adults during walking. Results show increased knee extension torque and muscle activity with biofeedback, suggesting potential benefits for enhancing knee extensor activation and mobility in older adults.
