@Georges: first, they're
orthotic limbs not
prosthetic (legs => ortho, arms => prostho) he's wearing (made of carbon fiber), and J4D's right, they not robotic. He might have been wearing the C-leg from Otto Bock or Reho-Knee from [edit] Ossur [/edit]. Second, they already cover them with silicon "skin", some even get tatoos or hairs on them. Otto Bock released a machine that scans the color tone of one's skin to manufacture the cover with the same shade. However, those who pick the iLimbs like to show them off. Also, Lebanese students have already designed robotic arms, it's nothing new, but this is pneumatic based (hence the post).

@J4D: Who said we don't have professionals in electronic based limbs?! You want to specilaize in them, continue a Masters degree in biomedical engineering, then complete 3 courses in rehabilitation at AUB. Then you get certified by the Lebanese board for artificial limbs. Then you either work for a company like Orthocare in Jevinor, or you become a representative for companies abroad and you go to physical rehab centers when you're needed. Note that you have to attend amputation procedures to make sure blade-happy surgeons don't cut off too much of the limbs and to reserve the condition of the nerves when they're good. Hell; I'll even give you brochures on how to get certified. My dad is a prosthetic and orthotic biomedical engineer, how do you think I know so much about them? PS: Lebanon leads the Middle East in the field, and despite the fact that a lot of rehab centers are opened, they all flock to Lebanon or ask for Lebanese professionals to swing by. Be proud to be a Lebanese for a change :)
