16]. When placed inside the robot, the knees and feet of the participant are each attached to a pneumatic cylinder (Fig.1a). The arrangement of the cylinders allows for one-degree of freedom flexion and individual extension movements of each leg, ...
EMG-based interface.An amputated patient using a Targeted Muscle Reinnervation (TMR) EMG-based interface for the control of an active prosthetic arm [116]. With the TMR EMG-based interface, the patient could control a 6 DOF prosthesis consisting of shoulder flexion, humeral rotation, elbow flexio...
The participants sat at a table and rest the arm holding the phone with their elbow on the table (see Fig. 10b). All experimentation was carried in an open plan office without restrictions on the environment noise. During our experiment, usual office noise was present (people moving, ...
With the local loss coefficient Kll of Gate valve, Tee, 90° Elbow calculated as in [37]. 3.3.2. The Real Power of Pump The actual capacity of the pump is calculated according to the following formula [37]: 𝑃𝑝𝑢𝑚𝑝=𝐺pw.Δ𝐻𝜂𝑝𝑢𝑚𝑝.𝜌𝑝w (W) with ...
In [18], an improved ADRC with extended state observer (ESO) and finite time stable tracking differentiator (FTSTD) was utilized in the flexion and extension motion of shoulder and elbow joints, which possess the disturbance rejection ability and robustness against parametric uncertainties. In [19...
In this paper, a combined control strategy with extended state observer (ESO) and finite time stable tracking differentiator (FTSTD) has been proposed to perform flexion and extension motion repetitively and accurately in the sagittal plane for shoulder and elbow joints. The proposed controller improv...
Based on the analyzed literature, we conducted activities concerning the development of a device used to assist the upper limbs about the shoulder and elbow with a exoskeleton- type kinematic architecture. The device has four motorized degrees of freedom (DoF), actuated by pneumatic muscles. After...
consideration was given to mounting the electric motor on the outside of an elbow during the design phase, however the perceived likelihood of rotordynamic issues arising from having to significantly extend the shaft curtailed this idea. Regardless, the potential for heat transfer from the motor casi...
