Contact Sensing from Force Measurements
This paper addresses contact sensing, i.e. the problem of resolving the location of a contact, the force at the interface and the moment about the contact normals is presented. Called \intrinsic" contact sensing for the use of internal force and torque measurements, this method allows for practical devices which provide simple, relevant contact information in practical robotic applications. Suc...
متن کاملMicrofluidic tactile sensors for three-dimensional contact force measurements.
A microfluidic tactile sensing device has been first reported for three-dimensional contact force measurement utilizing the microfluidic interfacial capacitive sensing (MICS) principle. Consisting of common and differential microfluidic sensing elements and topologically micro-textured surfaces, the microfluidic sensing devices are intended not only to resolve normal mechanical loads but also t...
متن کاملThigh-calf contact force measurements in deep knee flexion.
BACKGROUND Knee models often do not contain thigh-calf contact which occurs in deep knee flexion. Thigh-calf contact is expected to reduce muscle forces and thereby affects internal stresses in the knee joint. The purpose of this study was to measure thigh-calf contact forces. Two deep knee flexion activities were selected: squatting and kneeling. METHODS Ten healthy subjects participated in ...
متن کاملFrequency-domain force measurements for discrete event contact recognition
Discrete event recognition based on force measurements in the frequency-domain is presented. The force signals arise from interaction between the workpiece and the environment in a planar assembly task. The discrete events are modeled as Hidden Markov Models (HMMs), where the models are trained oo-line with the Baum-Welch re-estimation algorithm. After the HMMs have been trained, we use them on...
متن کاملSU-8 force sensing pillar arrays for biological measurements.
The generation and sensation of mechanical force plays a role in many dynamic biological processes, including touch sensation. This paper presents a two-axis micro strain gauge force sensor constructed from multiple layers of SU-8 and metal on quartz substrates. The sensor was designed to meet requirements for measuring tactile sensitivity and interaction forces exerted during locomotion by sma...
