Waldo (short Story) - The Waldo

The Waldo

A typical illustration of the tools in the story is Waldo's handling of his need to perform micro-dissection on the scale of cellular walls. He uses human-sized waldoes to make smaller waldos, then uses those to make even smaller waldoes, and continues the series until he has waldoes small enough to work at the cellular scale.

There are three main factors involved in Heinlein's description of the tools:

• They work like human hands: not with a single active lever or twenty different tools, but with components arranged and with actions like human hands. The operator puts his or her hands in "gloves" and the waldos repeat the movements of the hands.
• They work in conjunction with viewing equipment that lets the user see the waldos as if they have the size and action of his own hands. This, in conjunction with the first factor, means that waldos are a "no-training" tool: if you know how to use your hands, you can use waldos.
• They allow work to be done remotely, in the next room or many miles away, or in an environment that could kill a human or be contaminated by human presence. They can be a different size from normal human hands: either huge for building construction or tiny for micro-manipulation.
