Hobby Robotics

Finally a robotics book that doesn't waste time on blinking LEDs. I'm building a small rover for a school project and the chapter on differential drive platforms was exactly what I needed. The PID tuning procedure worked on the first try—my robot goes straight now. The tables for materials and fasteners are worth the price alone. I've got this open on my bench next to my laptop and it's already covered in solder flux.

It's a decent reference, but I was hoping for more on the control theory side. The PID section is practical but doesn't explain the math enough for me to adapt it to a more complex system. Also, some of the tables assume you have access to a machine shop, which I don't. Still, the troubleshooting chapter saved me a few hours when my servo was jittering. Not bad, but not the deep dive I expected.

As someone who's been doing Arduino projects for a couple of years, I appreciated that this book skips the basics. The gear ratio tables and motor selection charts are super useful—I used them to rebuild my robot arm's shoulder joint and it's way stronger now. The instructions for installing threaded inserts were clear and worked perfectly. It's not a cover-to-cover read, but it's a great companion to have on the bench.

I bought this because I kept stripping screws in 3D-printed parts. The fasteners chapter alone is worth it—there's a table with exact torque values and tap drill sizes that I've taped to my wall. The troubleshooting section for PID loops was also helpful. My only complaint is that I wish there were more project examples, but the two included are solid. I'll be keeping this within arm's reach.

It's a useful book, but I found the organization a bit confusing. The reference chapters at the end are great, but I had to flip back and forth a lot when working on my project. Also, I wished the author included more on sensor integration, like how to mount encoders properly. That said, the motor control chapter cleared up a lot of confusion I had about H-bridges. It's a good addition to my library, but not perfect.

I'm a beginner with Arduino, and this book is a bit advanced for me. The material tables and formulas are helpful, but I had to look up a few terms. I did appreciate the step-by-step for building a differential drive robot—it got me moving. The troubleshooting tables are great, but I wish there were more photos and diagrams. It's a good reference for when I need to look something up, but I wouldn't recommend it as a first robotics book.

This is the book I wish I had when I started building robots seriously. The focus on mechanism design is exactly what was missing from my other resources. The table of torque specs for screws in plastic saved me from ruining a project, and the PID tuning procedure is the clearest I've ever seen. I've already recommended it to two friends in our robotics club. It's a permanent resident on my workbench.
