Ein is pick-and-place software for Baxter. See the installation instructions on our web site: http://h2r.github.io/ein/.
Ein can be used to control Baxter, make models of objects, detect, localize, and pick objects using these models. We can localize objects with Baxter to within 2mm, and pick objects hundreds of times in a row without a failure. The robot can also be used to create a "for" loop over objects, picking from an input pile, playing with an object (doing an arbitrary learning behavior that you choose), and then moving to the output pile. We have automatically processed hundreds of objects in this way as part of the Million Object Challenge.
We follow this branching model for Ein releases: http://nvie.com/posts/a-successful-git-branching-model/ so the development branch is develop, and master always contains the latest release.
