An approach for a computer in a robotic arm device attached to a patient to receive data identifying at least one protected area of the patient from a computing device of a medical professional. The approach includes the computer receiving instructions for one or more actions by the robotic arm device associated with the least one protected area of the patient from the computing device of the medical professional. Additionally, the approach includes the computer receiving sensor data associated with one or more movements of the patient from one or more sensors in the robotic arm device and determining that a hand of the patient in the robotic arm device is entering the at least one protected area. Furthermore, the approach includes the computer initiating one action of one or more actions by the robotic arm device that is associated with the least one protected area of the patient.
