Video: The Sample Transfer Arm: A helping hand for Mars

The mission to return Martian samples back to Earth will use a European 2.5 meter-long robotic arm to pick up tubes filled with precious soil from Mars and transfer them to a rocket for an historic interplanetary delivery.

Program teaches US Air Force personnel the fundamentals of AI

A new academic program developed at MIT aims to teach U.S. Air and Space Forces personnel to understand and utilize artificial intelligence technologies. In a recent study which the program researchers recently shared at ...

Is it OK to kick a robot dog?

Last Saturday night, a young woman out on the town in Brisbane saw a dog-shaped robot trotting towards her and did what many of us might have felt an urge to do: she gave it a solid kick in the head.

Deep learning may help to prevent salmon escapes in rough seas

Artificial intelligence can be of great benefit underwater and SINTEF, in collaboration with the research center SFI Exposed, is developing systems that will help to boost fish farm safety and security under harsh sea conditions.


Robot is a virtual or mechanical artificial agent. In practice, it is usually an electro-mechanical system which, by its appearance or movements, conveys a sense that it has intent or agency of its own. The word robot can refer to both physical robots and virtual software agents, but the latter are usually referred to as bots. There is no consensus on which machines qualify as robots, but there is general agreement among experts and the public that robots tend to do some or all of the following: move around, operate a mechanical limb, sense and manipulate their environment, and exhibit intelligent behavior, especially behavior which mimics humans or other animals. In South Africa, robot is an informal and commonly used term for a set of traffic lights.

Stories of artificial helpers and companions and attempts to create them have a long history but fully autonomous machines only appeared in the 20th century. The first digitally operated and programmable robot, the Unimate, was installed in 1961 to lift hot pieces of metal from a die casting machine and stack them. Today, commercial and industrial robots are in widespread use performing jobs more cheaply or with greater accuracy and reliability than humans. They are also employed for jobs which are too dirty, dangerous or dull to be suitable for humans. Robots are widely used in manufacturing, assembly and packing, transport, earth and space exploration, surgery, weaponry, laboratory research, and mass production of consumer and industrial goods.

Modern robots are usually used in tightly controlled environments such as on assembly lines because they have difficulty responding to unexpected interference. Because of this, most humans rarely encounter robots. However, domestic robots for cleaning and maintenance are increasingly common in and around homes in developed countries, particularly in Japan. Robots can also be found in the military.
