Star Wars depicts robotics which resembles current robotics technology, though at a much more advanced and developed level. Robotics in
Star Wars are generally divided into two categories, as in modern reality: military and civil.
Civil play important roles in assisting humans with labour chores (in this case farming) similar to the civilian robots seen in
Star Wars. Some robots in the
Star Wars universe are capable of performing multiple types of tasks, while others can only perform one type of task. For example,
21-B is built for the sole purpose of performing medical tasks. Others, such as humanoid protocol droids like
C-3PO, are built for multiple purposes. These range from basic physical chores to translating between different forms of communication, including with sophisticated computers and other forms of artificial intelligence. Other, barrel-shaped robots, such as
R2-D2, are built with multiple features and capabilities. These include repairing and programming advanced devices, as well as maintaining them. The basic concepts and purposes for robotics in
Star Wars, as in real life, are to reduce human labour, assist humans with sophisticated requirements, as well as store and manage complex information. Another parallel to the modern world is the use of robots in
Star Wars for tasks not considered safe or acceptable for humans. Robots are also seen as a source of cutting human labour costs. A related development is the creation of the droid
BB-8 for the film
Star Wars Episode VII: The Force Awakens (made by different manufacturers). In the film, BB-8 is a semi-automated robot, operated by remote control, unlike C-3PO (played by
Anthony Daniels) and R2-D2 (played by
Kenny Baker), who were portrayed by actual actors. The BB-8 toy is operated by remote control, but it also has some independent features, and shares its manner of movement and other features with the film's BB-8. In 2010,
NASA developed robots inspired by the hovering remote-controlled droids, seen in the
Star Wars films and other media, and used by the
Jedi for
lightsaber combat training. These robots were used in NASA space stations for experimentation. Also in 2010, a hacker developed similar robots, but only capable of floating beyond a limited magnetic range.
Military developed by
Boston Dynamics (now owned by
Google) in co-operation with an agency of the
United States Department of Defense Military robots in the
Star Wars universe are built on the same principles as modern military robotics. While most military robots in the modern world are designed in various shapes, depending on their purpose, the military robots of the
Star Wars universe are primarily humanoid, and built to imitate live,
organic soldiers, mainly human ones. A major similarity between modern military robotics and those of the
Star Wars universe is that different robots are built and designed for different specific purposes, whether those purposes are ground warfare, maritime warfare, aerial warfare, or space warfare, as seen in the
Star Wars prequel films. Such uses are considered unpractical and unfeasible by current means, given the sophistication and resources each individual unit would require. Another significant, recognizable distinction of the robots in the
Star Wars universe, whether military or civilian, is their strong sense of independence and self-awareness, compared to current robots. This is mainly due to
Star Wars robots having much more advanced sensors and self-computing systems than current robots do. Despite the limited abilities of current robots, Dr. Jonathan Roberts, director of CSTRO Autonomous Systems Laboratory, proclaims that the role of robots in assisting humans is going to increase, similarly to what is seen in
Star Wars. The
Christian Science Monitor reported in 2011 that an American blogger, out of patriotism, tried to raise money to build a robotic
AT-AT for the
US military. Heikko Hoffman, a robotics expert from
HRL Laboratories, who was not associated with the project, claims that AT-ATs are possible, though some of their designs should be changed from those seen in the
Star Wars universe, for safety, and for financial and operational costs. The project, though not terminated, was suspended, due to intellectual property concerns from Lucasfilm. In 2012, the
United States Navy built a robot modelled after C-3PO, but appears to function for both military and civilian purposes. ==Macro-engineering==
