All the computer science in the world will not help you build a robot. Computers can be used to build robots, but the robot is not a computer. What is needed is to copy nature. Robot should be built with neurons, like we are. But, you say, "There is no way to build neurons." That was true ...

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 numb...

To describe or design robots, you need a language. Mathematics is a language. You know some of it and the rest of it I am beginning to know. The words you need are: sets, variables, number symbols, number base, digits, system, function, arithmetic, algebra. The new math words you will need are: sens...

I have some numeric H bridge nodes. They are about 1/2 x 3 3/4 inches. They accept an integer input and produce a pulse proportional to the integer size. The node (MONode) is a PIC running a transister H bridge. Give me your email and I will send you a schematic. I have a whole system of these nodes...

Jameco and edmund scientifics have some small kits and motors and such.<p>http://www.scientificsonline.comhttp://jameco.com<p>[ February 15, 2002: Message edited by: Harold ]</p>

Thanks. The least possible brain function is simple negation. Neurons are a mathematical function although neither neurologists or mathematicions know that. My assumption is, since most of nature is, brains are mathematical functions. I have about 16 functions so far. The main thing is, all the func...

Thanks for the comment. I got interested in AI in 1958. I gave up on it in 1990. Since brains are different in size, there must be a least brain. If there is a least brain it must have a function. I have an algebra and a complete system of tools to build brains of any size. I will be glad to send yo...

You sure you cannot repair the old centrifigal govorner? Nothing on it should break. If the shaft from the engine is broken, it will not turn and will not regulate. Can you look at it?<p>By the way guys, an eight bit subtraction is 256 parallel XOR operations. A = x - y is a universal control system...

Those centrifigal govorners were developed for the first steam engines. Amazing. The speed regulator needs to sense rotary speed, so speed is an output. The throttle regulates speed, so it will be an input for your regulator. The units are different so you need to take that into account. RPM needs t...

Brains, including those needed by robots are far beyond logic. To make a decent brain you cannot use computer design rules. Logic was invented to use on binary data. Boolean logic is below the level of arithmetic, that is more primative. For example a simple 8 bit subtraction is 256 exclusive or ope...

Hal algebra is a language that maps to HalNodes and cables that designs or describes any robot or machine with sensors and motors. Sensors read nature and write data streams. Motors read data and work on nature. Brains mediate between sensors and motors, reducing the input complexity to match that o...

You might be able to read the code in the chips if they are not protected and you have the system. May be worth more than the chips. I don't even have PIC16C73A in my old microchip data books, but they should have ADC.

a machine constructed to read some properties of nature, feed that to a brain or motor which writes some action on nature. The data flow is: Nature -> Sensors -> brain -> Motors -> Nature Note the loop. Sensors read nature and write data. brains mediate between sensors and motors. motor read data an...

How would you like to have a tool that does not produce a computer program but a robot program. This tool you can write on a napkin.
