Estimation of muscle activity is very important as it can be a cue to assess a person’s movements and intentions. If muscle activity states can be obtained through non-contact measurement, through visual measurement systems, for example, muscle act

Excessive muscle tension is implicitly caused by inactivity or tension in daily activities, and it results in increased joint stiffness and vibration, and thus, poor performance, failure, and injury in sports. Therefore, the routine measurement of mu

The majority of humanoid robots adopt flat feet, a choice that can limit their performance when maneuvering over uneven terrains. Recently, a soft robotic foot designed to adapt to the ground was proposed to overcome part of these limitations. This p

Instead of human subjects, humanoid robots can be used as human dummies to test the human-designed products. We propose a controller that uses wearable assistive devices (also referred to as exoskeletons) to reproduce human movement in the evaluation

Robotic feet play a fundamental role in the walking performance of a biped robot. Feet are essential to maintain dynamic stability and to propel the body during walking. They may ensure stability on uneven terrains. Yet, complex feet are seldom used

This paper presents a method to estimate cost weights of cost functions and multiple joint motion time-series values of humanoid robots easily, using functional principal component analysis (FPCA) instead of direct optimal control (DOC) and inverse o

We address the problem of calculating complex Jacobian matrices that can arise from optimization problems. An example is the inverse optimal control in human motion analysis which has a cost function that depends on the second order time-derivative o

Inverse Optimal Control (IOC) is a useful technique to estimate the importance of cost functions used to optimally control a system by observing its motion. The computational cost of IOC increases with the complexity of the system. This study aims at
