November 2011 update: new building, new machines

Five months ago, I wrote that we “just finished a big facility expansion that was taking up a lot of my attention this year, so I have some more time now …” Well, that turned out to be wrong. It’s also been over a year since I started this blog, and so far, I am way behind my target of an article per week. It doesn’t help when I don’t post for four months, but some exciting stuff has happened in that time. Continued…

Simple 3pi Projects for the Arduino IDE

Posted by Ben on 8 August 2011

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.
