Programming topics well protected, especially language and pbForth NQC, and install the firmware replacement. Although this book is much stronger in covering software from the mechanical aspects of robot design, assembly plan incorporating many useful features that can be used in the design itself, including the transmission of directional and single-motor grabber. Two projects provide a clear demonstration using the IR port for communication. For this simple robot does not matter, but to Minerva (a rather complicated and a very good learning example) they are a bit difficult to follow. The final chapter of this book includes informative discussions to build their own sensors, sensor inputs to the RCX, and sensor input configuration of your programs. However, if you are looking for a book that introduces building Mindstorms robots with useful examples and include their programming, replacing their firmware, and introduce censorship for their buildings, this is a perfect book Keogh. - John Topics covered: Building a robot using the Robotics Invention System, RCX programming using RCX Code, NQC, pbForth, and C, using sensors and actuators, gears, transmission and pulleys, obtain and install pbForth and Lego firmware replacement, communication with and between robot using infrared port, and make their own sensors.
