"Robot as cyborg extension. In the second paradigm, the robot is physically merged with the human to the extent that the person accepts it as an integral part of his/her body. For example, the person would view the removal of his/her robotic leg as an amputation that leaves him/her only partially whole. Consider a robot that has an intimate physcial connection with ones’s body, such as an exoskeleton for a soldier or a prosthetic of an amputee. Emotions play a critical role in connecting the mind with the body and vice versa. Note that the performance of one’s physical body changes depending on whether one is relaxed or exhilarated. Although a robotic leg would not “have emotions” itself, it is important that it adapt its characteristics to match those of the rest of the body in accordance with the emotional state of the human to avoid imbalance. If the robotic extension were able to sense and recognize the person’s emotional state (perhaps via physiological changes in his/her body) it could adapt its operating characteristics appropriately. Under calmer times the robotic extension could go into energy conservation mode since power demands are lower. However, in high stress situations, the robot could change its operation parameters to significantly augment the person’s strength or speed."
