In autonomous systems, such as robotics, the goal has always been to enable `intelligent’ actions and interactions with the environment. Unfortunately, this goal has been elusive, yet is potentially on the horizon. Intelligent semi--autonomous systems are defined as systems where both humans and automation tight")
