Not as big a need to protect the robot, but the robot might be trying to protect other people, and thus would require some method of disabling an attacker. Egregious example: a hostage situation, or an active shooter situation. With a remote controlled robot, you can use less lethal weapons against the attacker, since the robot can be sacrificed (whereas I assume we'd rather not sacrifice police officers).
