The Big Black Ball

If any of my readers are old enough to remember a classic SF TV show called "the Prisoner" this story will bring back fond memories, and perhaps a chill.

A large black ball, originally designed by Swedish scientists for use on Mars, could be the latest weapon in the war against burglars.

The device, developed at the University of Uppsala, acts as a high-tech security guard capable of detecting an intruder thanks to either radar or infra-red sensors. Once alerted, it can summon help, sound an alarm or pursue the intruders, taking pictures.

It is capable of travelling at 20mph, somewhat faster than a human being. Even worse for intruders, the robot ball can still give chase over mud, snow and water....

While the current version can only raise the alarm, it could be adapted to corner an intruder if the customer wanted, [the inventor] added.

I want one!
