In this paper, we design a new controller for power-assisted wheelchairs. Conventional
power-assist controllers only focus on the amplification of the human input force using …

Due to the recent trend of the application of robots and other mechatronic devices to human
life support, the force control draws more attention than ever. However, to use force sensors …

This paper suggests control algorithm for a robot manipulator which has biarticular muscle
torque input in addition to the conventional two monoarticular muscle torques. Using a …

In the past 20 years, control methods for two-inertia systems have gradually changed from
semi-closed control to full-closed control in order to achieve higher precision positioning …

Our proposed power-assisted wire suspension system has three advantages. First, the
structure is simple, and the cost is lower than that of other rigid systems, because the …

This paper proposes a method to assist human force acting on electric bike without using
costly torque sensors via a model-based impedance control technique. In general, electric …

In this study, a new active impedance control method of a knee joint orthosis is proposed by
using a nonlinear observer to estimate the human joint torque. The proposed method is an …

Mechatronic systems that physically interact with humans should guarantee safety, as well
as stability and control performance. Mechanical impedance is an effective means to …

The collaboration between a human operator and a robotic manipulator for performing a
joint task is the main topic of this article. One of the most common tasks involves transporting …

Purpose This paper aims to deal with the design of new hybrid approach for the assistance
of the flexion extension movement of the knee joint. Design/methodology/approach The …
