Crab Robot Helps Remove Stomach Cancer 83

redletterdave writes "Singaporean researchers have created a miniature robot with a pincer and a hook that can remove early-stage stomach cancers without leaving any scars. Mounted on an endoscope, it enters the patient's gut through the mouth. It has a pincer to hold cancerous tissues, and a hook that slices them off and coagulates blood to stop bleeding. With the help of a tiny camera attached to the endoscope, the surgeon sees what's inside the gut and controls the robotic arms remotely while sitting in front of a monitor screen. The robot has already helped remove early-stage stomach cancers in five patients in Hong Kong and India, using a fraction of the time normally taken in open and keyhole surgeries that put patients at higher risk of infection and leave behind scars."

    That is not a robot. It is a tele-operated tool, related to a waldo (A waldo mimics one's movements precisely - See Heinlein's story Waldo). Call it a waldo, just to keep it simple. For example, a powered suit worn by a person is a very complex waldo.

    A robot is not completely operated by a human. It can be partially so; the Mars rovers are robots that do what they are told, but interpret the commands with their own programming, as they are 45 light minutes away and cannot be controlled directly.

    A robot has it's own "brain". It independently operates in its environment by its own perception and judgement.

    A claw on a stick is not a robot. Words are important. These things have names, and confusing the terminology muddles communication.

No problem is so large it can't be fit in somewhere.
