Odex I Robot
The Old Robot Website has a fantastic collection of old robots, some quite advanced for their time like the six-legged Odex I shown here.

Heathkit Hero I Robot
I still have a soft spot for the Heathkit Hero I robot which I built as a teenager and ensured that I was never invited to any of the really good parties… Those parties – bad 80s hair and all – are long fogotten but I can still work a soldering iron like no one else!

Postulated in 1971, a fourth passive circuit element called a memristor has been invented by a team from HP Labs. Circuit theory books, which will have to be rewritten, teach the existence and use of three passive circuit elements: the resistor, capacitor, and inductor. The memristor, short for memory resistor, changes its resistance based on the history of the flow of charge through the device. It essentially behaves like a non-linear resistor with memory. The device improves in performance the smaller it is made. The memristor can be used as both a digital and an analog device, depending on how current is passed through it. The applications are astounding, including computers that do not need to boot up, the elimination of disk drives, more energy efficient devices, and analog computers that can remember and associate patterns in the same way as the human brain.
