Department of Computer Science of University of Massachusetts Lowell (UML) observed a robot named DORA. This robot is designed to help people who use wheelchairs to open the door.

A low cost robot arm system is developed that will increase a person’s accessibility to indoor spaces by unlatching door knobs and door handles. Implemented is a minimized arm configuration for use with a wheelchair or mobile platform and a gripper design that utilizes only a single motor to turn door knobs and door handles. This proof of concept prototype demonstrates how an arm with many degrees of freedom is not required if we target the expectations for its use.

The word robot comes from the Czech word “robota”, meaning “forced labor.” The stuff of science fiction robotics in the 21st century is different than your parents or your grandparents’ ideas of robotics. What used to be thought of as futuristic improbability is now becoming a reality.

There are, theoretically, three Laws of Robotics. The Laws of Robotics were developed by a small group of scientists who believe that robotics is the wave of the future. The first law, referred to as law zero, is that a robot may not injure humanity, or, though inaction, allow humanity to come to harm. The second law states that a robot may not injure a human being, or, through inaction, allow a human being to come to harm, unless this would violate a higher order law. This law was created so that mankind would seek not to create robots that would harm people. The third law is that a robot must obey orders given it by human beings, except where such orders would conflict with a higher order law. And finally the final law is that a robot must protect its own existence as long as such protection does not conflict with a higher order law. These were used in a recent Hollywood movie however many people don’t know that the Laws of Robotics actually exists.
