Would you trust a robotic arm to give you a massage? It is another thing when a robotic arm gives you a roller coaster ride but a whole different feeling when it performs a massage on you. It just feels like one day or another it will have a bad day and break every bone in your body. Machines make mistakes just like us but when this puppy makes one it will cost you a rib. Would I trust this? I guess it is not as bad as getting massaged by snakes.
