PLEASE NOTE: You don't even need the compiler or Visual basic if you are building the robots as they are described in the book because the book lists the hex files needed to program the microcontrollers. The visual basic application that is built in chapter 6 (which completely explains how to do it) is also available for free on the authors website - Yep it is actually there. The great thing about this book is that it stands alone because all of the programs and the hex files are listed in the book so that you don't actually need to access the authors website at all - the book is complete on its own!!

This is another great book by Williams - the diagrams, pictures and descriptions are very well done.

"Great book!!"
This book is thorough with nice instructions and easy to follow. I think that this is a very good book if you actually want to build some insteresting robotics projects and learn!!

"Fabulous resource - Great robotics book!!"
This is actually a very well written and researched book!! It starts off with the fundamentals of PIC microcontrollers and how to program them. The first project is a great robot arm design. Like his other two books, the mechanical drawings and illustrations are beautiful and easy to follow. The arm includes a wrist and a human type of hand\gripper. After the mechanical portion of the arm is completed, an interface board is built. This interface board connects to your personal computer. Once again, all of the printed circuit board designs are presented making construction easy. The next chapter delves into writing visual basic software to control the arm - this was very valuable information for me and I'm sure many other roboticist who want to know how to program the PC to control robots or other devices. This chapter alone is worth the price of the book! The next chapter is all about speech recognition and builing a circuit board with a head-set to control the robot arm with spoken commands. This is the real thing and the system works quite well. The next chapter shows you how to build a humanoid head that displays emotions through facial expressions. This chapter has some interesting info about the science of facial mnemonics. I would probably never build the head but this project takes advantage of the interface board and software developed in the previous chapters.
Then final project is a bipedal (two legs) walking robot. The design of this robot is amazing!! Williams does a great job with the mechanical design again - just like the robots in Amphibionics and Insectronics. The robot incorporates a pic microcontroller with analog-to-digital converters that are used to monitor the sensors on the legs so that a stable walking algorithm can be programmed. Once the robot is programmed to be able to walk, an infrared sensor is used so that the robot can avoid obstacles. This robot can walk forward, reverse, turn right and turn left. The printed circuit board artwork and all the software is included in the text. I learned a lot by builing this robot and it is VERY cool to show this one off. This robot can actually do a lot of things and the fact that it actually walks on two legs is amazing.

Just a note about the last posting by Stanley J Morris - building robots is going to cost you money - nothing is free and that includes the software compiler written by a company that the author is not affiliated with in any way - he does not profit from it.

At the same time - all of the software that is developed in the book - including the awesome VB Control software package - can be downloaded for free from the authors web site.
