Simple 3pi Projects for the Arduino IDE

Simple 3pi Projects for the Arduino IDE

These projects by Daniel J. Sullivan are intended to introduce novice users to all the components on the 3pi robot and how they can be used while programming with the Arduino IDE. Each project builds on the one before it, and comments within the programs are used to provide background information when new items are introduced.

Continuous-rotation servos and multi-turn servos

Continuous-rotation servos and multi-turn servos

As I discussed in the introduction to servos, one of the consequences of hobby servos’ intended use is that rotation range is limited to about 180 degrees. In this post, I will talk about two exceptions to this general rule: continuous-rotation servos and multi-turn servos. Each of these products loses some features in return for increased rotational range, so none of them are the ideal actuators many would like them to be. There are some specialty servos developed for robot applications that get around the limitations, but those servos are not as standardized and do not really fit into the hobby servo category, so I am not going into any more detail on those beyond mentioning that they exist.

How an idea becomes a product

How an idea becomes a product

The Wixel Shield for Arduino that we released today represents a personal milestone because of what I did not do on it: the shield is the first electronic product made by Pololu that I did not design. That’s not to say I did not have some input on it or that other engineers here did not have substantial contributions to other products, but the Wixel Shield is a first because the basic product concept, the circuit design, and physical implementation (i.e. the PCB layout) were all done by someone else. We also just finished a big facility expansion that was taking up a lot of my attention this year, so I have some more time now to think about our design process and what it takes to go from a new idea to a finished product.
