RISAssisted Spatial Sit-to-Stand Prediction-Part 1: Virtual Healthy Elderly Individuals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Sit-to-stand (STS) motion is a key determinant of functional independence for the senior people. This paper extends a predictive dynamics formulation previously reported to predict the assisted STS motion, i.e., the motion ...
Digital Human Forward Kinematic and Dynamic Reliabilities
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Probabilistic methods have been applied to many problems in various fields of study. There are many distinct applications of probabilistic design in the biomechanics field, in particular. Traditionally, deterministic methods ...
Grasping Force Optimization Approaches for Anthropomorphic Hands
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An appropriate choice of contact forces for anthropomorphic robotic grasping devices is important for achieving a balanced grasp. Too little applied force may cause an object to slip or be dropped, and too much applied ...
Examining the Robustness of Grasping Force Optimization Methods Using Uncertainty Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The development of robust and adaptable methods of grasping force optimization (GFO) is an important consideration for robotic devices, especially those which are designed to interact naturally with a variety of objects. ...
Modeling and Prototype Testing of Flows over Flip-Bucket Aerators
Publisher: American Society of Civil Engineers
Abstract: The paper deals with a unique spillway which incorporates an aerator in each flip bucket with the intention to aerate the flow and avoid subatmospheric air cavities enclosed by the jets. In terms of jet breakup and stability, ...
Assisted Spatial Sit-to-Stand Prediction—Part 2: Virtual Injured Elderly Individuals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Sit-to-stand (STS) is a challenging task, especially for injured elderly in their daily life. This paper presents Part 2 of the assisted spatial STS computational motion prediction to investigate the effect of a unilateral ...
Single Task Optimization-Based Planar Box Delivery Motion Simulation and Experimental Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Box delivery is a complicated task and it is challenging to predict the box delivery motion associated with the box weight, delivering speed, and location. This paper presents a single task-based inverse dynamics optimization ...
Development of a Finite Element Model of the Human Wrist Joint With Radial and Ulnar Axial Force Distribution and Radiocarpal Contact Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study presents a comprehensive finite element (FE) model for the human wrist, constructed from a CT scan of a 68-year-old male (type 1 wrist). This model intricately captures the bone and soft tissue geometries to ...
Simultaneous Prediction of Multiple Unmeasured Muscle Activations Through Synergy Extrapolation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Estimating muscle forces is crucial for understanding joint dynamics and improving rehabilitation strategies, particularly for patients with neurological disorders who suffer from impaired muscle function. Muscle forces ...
Prescribed Performance Backstepping and Sliding Mode Control for Automated Platoons With Internal Type-2 Fuzzy Logic and Exponential Spacing Policy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study presents a control strategy employing a hybrid backstepping and sliding mode control (BSMC) approach for automated platoons. The control scheme integrates an exponential spacing policy tailored to varying driving ...
