Robot that roams the body to seek and destroy cancer

The idea of a beetle moving around inside your body may be the stuff of horror films. But scientists believe an insect-shaped robot could be a major weapon in the fight against cancer.
The device, just under an inch long, is designed to be inserted into the body through a small incision.
Once inside, doctors can control its movements and direct it to areas where investigations are needed.
However, unlike the plot of the 1966 Raquel Welch film Fantastic Voyage - which featured a microscopic crew and submarine travelling through a scientist's bloodstream - this device could not be inserted into blood vessels because it is too big.
I don't think devices that can do precisely that will be long in coming, and they won't need cables connecting them to the outside world either.
