Experimental validation of the Lower Leg Trajectory Error, an optimization metric for prosthetic feet
… a novel, quantitative method called Lower Leg Trajectory Error (LLTE) which maps the mechanical design of a prosthetic foot to its biomechanical performance, we can optimize the compliance and geometry of a passive prosthesis to replicate able-bodied gait and loading on the foot using …

Evaluating UAV Visual-Inertial Odometry Trajectory Error and Feature-Level Metrics over Repetitive Floor Patterns
… produce ambiguous correspondences that introduce errors into the trajectory estimate. Despite the prevalence of repetitive textures in indoor UAV operating environments such as warehouses, manufacturing facilities, and infrastructure corridors, the specific impact of different repetitive pattern …

Design of a Novel Mechatronic System to Test Prosthetic Feet Under Specific Walking Activity Loads and Evaluate their Lower Leg Trajectory Error
… effort, is not fully understood. The lower leg trajectory error (LLTE) is a novel prosthetic foot performance metric that provides a quantitative connection between the mechanical characteristics of a foot and the expected gait of an amputee. Thus far, the LLTE value of a foot has only been …

Integrated Prosthetic Leg Design Frameworks for People with an Above-Knee Amputation
… walking. Using these results, I created the Hip Trajectory Error (HTE) framework for designing prosthetic feet specifically for people with an above-knee amputation. The HTE framework takes into account the lack of ESF by incorporating the shock absorption function of ESF within the prosthetic …

Development and validation of a novel framework for designing and optimizing passive prosthetic feet using lower leg trajectory
… feet to best replicate physiological lower leg trajectory under typical ground reaction forces. The goal of developing this framework is ultimately to design a low cost, mass manufacturable prosthetic foot for persons with amputations living in the developing world. Despite a vast body of …

Design and Mechanical Validation of Commercially Viable, Personalized Passive Prosthetic Feet
… or not commercially viable. The Lower Leg Trajectory Error (LLTE) design framework provides an oportunity for designing high-performance, amputee-specific prosthetic feet; however, previous foot prototypes were designed as experimental prototypes to demonstrate the LLTE theory, not to …

Development and Validation of a Passive Prosthetic Foot Design Framework based on Lower Leg Dynamics
… Here, we further developed the lower leg trajectory error (LLTE) framework, a novel design methodology that connects the mechanical characteristics of a prosthetic foot to the user's walking pattern. We extended the methodology to describe the entire prosthetic step for multiple walking …
