The paper presents a mechanical forearm mechanism to extend the pronation and supination (P/S) movement of the trans-radial amputee when he/she is able to conduct the P/S motion partially with his/her remaining forearm. The P/S motions of the existing prostheses and robotic arms developed till now are completely different from those of the human. When we(More)
The paper presents how to extract bone lengths from the captured MRI data, ultimately, to determine the design parameters for prosthetic forearm. The original bone lengths of the lost arm are estimated from the MRI data regarding the living arm at opposite side. In detail a right forearm amputee participates in the experiment and the MRI data regarding his(More)
The paper presents a design idea of prosthetic forearm for trans-radial amputees based on body power itself not on an external motorized power. This study aims at realizing humanlike pronation and supination for prosthetic forearms. The proposed has passive joints driven by residual motion of the amputated limb. For an experimental verification, we show(More)
This paper presents a prosthetic hand control system for trans-radial amputees based on electromyogram (EMG) signal processing. This study aims at extracting the muscle commands from surface electromyogram (sEMG) for controlling the prosthetic hand connected to the amputation part. The proposed prosthetic hand is developed so as to realize 10 joints(More)
