The basic principle of robotics and AI

Image
Artificial intelligence applied to robotics development requires a different set of skills from you, the robot designer or developer. You may have made robots before. You probably have a quadcopter or a 3D printer. The familiar world of  Proportional Integral Derivative  ( PID ) controllers, sensor loops, and state machines must give way to artificial neural networks, expert systems, genetic algorithms, and searching path planners. We want a robot that does not just react to its environment as a reflex action, but has goals and intent—and can learn and adapt to the environment. We want to solve problems that would be intractable or impossible otherwise. Robotics or a robotics approach to AI—that is, is the focused learning about robotics or learning about AI? about how to apply AI tools to robotics problems, and thus is primarily an AI using robotics as an example. The tools and techniques learned will have applicability even if you don’t do robotics, but just app...

The capabilities of Node.js

     Node.js is a platform for writing JavaScript applications outside web browsers. This is not the JavaScript we are familiar with in web browsers! For example, there is no DOM built into Node.js, nor any other browser capability. Beyond its native ability to execute JavaScript, the bundled modules provide capabilities of this sort: Command-line tools (in shell script style) An interactive-terminal style of program that is  Read-Eval-Print Loop  ( REPL ) Excellent process control functions to oversee child processes A buffer object to deal with binary data TCP or UDP sockets with comprehensive event-driven callbacks DNS lookup An HTTP, HTTPS, and HTTP/2 client/server layered on top of the TCP library filesystem access Built-in rudimentary unit testing support through assertions The network layer of Node.js is low level while being simple to use.  For example, the HTTP modules allow you to write an HTTP server (or client) using a ...
