Always wanted to be massaged by a robot
Massage Robotics has at the CES 2019 with its prototype of the robot massage therapist again drawn attention to massages using robot arms. With the help of voice control you could influence the strength of the massage.
Massage in case of injuries
Experiments with the use of robot arms for massage have been going on for some time now. For example, Emma, the massage robot made by the NTU in Singapore. Based on a scan of your back and a comparison in the database, a program is selected after which the robot arm starts working on the massage. The head of the robot arm contains 2 parts, one feels like a human thumb and the other like a human palm.
