This article describes the process of development of the robotic foot for the six-legged walking robot Messor. In order to allow the robot to negotiate uneven surfaces and to walk on a compliant ground, the foot includes the sensing device which provides information on contact forces between the foot and the ground. At first, the foot with single-axis force measurement unit is described. Next, ...

Abstract Foot impedance plethysmography was implemented using two types of electrodes (dry and capacitive) sole force sensors. The latter are commonly used for assessing diabetic foot ulcers (DFU). For plethysmography, a tetrapolar configuration has been with three different plantar setups: four skin contact electrodes, capacitive Force Sensing Resistors (FSRs). In this work, FSRs have consider...

The purpose of this study was to find the difference in foot pressure patterns when wearing smart walking shoes. Foot pressure measurement is an established tool for the evaluation of foot function [1]. These measurements assess the effect of structural changes, which may occur as a complication of pathologies such as diabetes, and therefore have been suggested as one of the key tools in ulcer ...

Despite intensive ongoing research, key aspects of the spatial-temporal evolution of the 2001 foot and mouth disease (FMD) epidemic in Great Britain (GB) remain unexplained. Here we develop a Markov Chain Monte Carlo (MCMC) method for estimating epidemiological parameters of the 2001 outbreak for a range of simple transmission models. We make the simplifying assumption that infectious farms wer...

Development of a planar biped robot is currently underway at Yeditepe University. The robot consists of lower extremities with a torso that are designed at anthropomorphic dimensions. This study describes the design and testing of a foot contact sensor for the biped robot. Dynamic stability of a biped robot is commonly measured by the zero moment point (ZMP) method. Experimentally, ZMP is measu...

Foot orthotic treatment is one of the major conservative methods used to handle foot problems. Total plantar contact foot orthoses are used to reduce and redistribute peak pressures. For the fabrication of a total plantar contact foot orthosis, the computer-aided design and computer-aided manufacturing (CAD-CAM) method has been applied. In this study, the plantar foot-orthosis interface pressur...

BACKGROUND Patellofemoral Pain Syndrome is one of the most common knee disorders among physically active young women. Despite its high incidence, the multifactorial etiology of this disorder is not fully understood. OBJECTIVES To investigate the influence of Patellofemoral Pain Syndrome on plantar pressure distribution during the foot rollover process (i.e., the initial heel contact, midstanc...

BACKGROUND Descending kerbs during locomotion involves the regulation of appropriate foot placement before the kerb-edge and foot clearance over it. It also involves the modulation of gait output to ensure the body-mass is safely and smoothly lowered to the new level. Previous research has shown that vision is used in such adaptive gait tasks for feedforward planning, with vision from the lower...

Background It is usually challenging to achieve surfaces that are highly adhesive, yet can be detached easily. Geckos’ foot hairs, however, can be easily detached from a surface even though they adhere to it strongly enough to hold the animal’s body against gravity. Inspired by Nature, a combination of strong adhesion and easy detachment in adhesion system can be achieved and the possibility of...
