In every child's development
they will remember that one
special toy. In Home Ec. class
of my 1st year of high school,
I was required to build that
toy to sell on the market. This
robotic walking weasel carried
a backpack that contained a
micro processor sensing the
depression of a sensor in the
weasel's tail. Push down on the
tail; watch the quadruped walk.
