Robot design tree

[hlreed]

A robot system is a set of actions and objects.
robot = {actions, objects}
Design starts with deciding what the objects are.
object = {volts XOR digital XOR numeric}
The object used determines the action possibilities so object must be decided first.
If object = volts you are analog and have no numbers. You cannot guarantee that O = I - R with volts, although you can easily construct the hardware for this.
If object = digital, you are right where everyone is. With a bit, you cannot do O = I - R. The only algebra you can do is Boolean, with AND, OR and NOT. This is not suitable for building a robot.
If object = numberic, then O = I - R is guaranteed and you have all algebra availible.
If you choose numeric then
actions = {+,-,o,a,d,i,z,g,l,is,gt,lt...}
That is all I have room for now. Ask me for Hal algebra.<p> [email protected]
