A large amount of pertinent info for a relatively small number of pages. The brunt of the information is for those with a substantial trig and calculus background in the engineering community. However, the first six chapters can be understood by an experienced technician, who would stand to gain a substaintially higher level of understanding of control systems and applications. So, if you're an electromechanical engineer or a robotics tech looking to gain more knowledge, you will benefit by having this book nearby for reference.
