Kinematic design of crab-like legged vehicles
Journal Article
Liu, A., & Howard, D. Kinematic design of crab-like legged vehicles. Robotica, 19(01), 67-77. https://doi.org/10.1017/S0263574700002861

In this paper, the kinematic workspace characteristics of a
crab-like legged vehicle are investigated using a 2-D model.
The alternative kinematic configurations and their corresponding workspace constraints are discussed, and the
vehicle configurat... Read More about Kinematic design of crab-like legged vehicles.

Whole body inverse dynamics over a complete gait cycle based only on measured kinematics
Journal Article
Ren, L., Jones, R., & Howard, D. Whole body inverse dynamics over a complete gait cycle based only on measured kinematics. Journal of Biomechanics, 41(12), 2750-2759. https://doi.org/10.1016/j.jbiomech.2008.06.001

This paper presents a three-dimensional (3D) whole body multi-segment model for inverse dynamics analysis over a complete gait cycle, based only on measured kinematic data. The sequence of inverse dynamics calculations differs significantly from the... Read More about Whole body inverse dynamics over a complete gait cycle based only on measured kinematics.

Predicting lower limb joint kinematics using wearable motion sensors
Journal Article
Findlow, A., GOULERMAS, J., Nester, C., Howard, D., & Kenney, L. Predicting lower limb joint kinematics using wearable motion sensors. Gait & Posture, 28(1), 120-126. https://doi.org/10.1016/j.gaitpost.2007.11.001

The aim of this study was to estimate sagittal plane ankle, knee and hip gait kinematics using 3D angular velocity and linear acceleration data from motion sensors on the foot and shank. We explored the accuracy of intra-subject predictions (i.e., wh... Read More about Predicting lower limb joint kinematics using wearable motion sensors.

A comparison of feature extraction methods for the classification of dynamic activities from accelerometer data
Journal Article

Driven by the demands on healthcare resulting from the shift toward more sedentary lifestyles, considerable effort has been devoted to the monitoring and classification of human activity. In previous studies, various classification schemes and featur... Read More about A comparison of feature extraction methods for the classification of dynamic activities from accelerometer data.
