What is the role of rehabilitation robots in upper limb care post stroke?

Very important. The post stroke treatment it is very complicated , it needs a lot of time and efforts from the patient and from the therapist.The role of the robots in the treatment it is very important and helpful. It helps with the functions lost , and the rehabilitation of the affected limb.
News to me. I admit to unfamiliarity with rehabilitation robots although there are machines that repetitively extend-flex limb joints to restore mobility. If this is what you mean, such "robots" could be a valuable supplement to therapy.
