Rethink Robotics just released a new update of Baxter SDK: Baxter Research Robot SDK 1.1.1.
The company, which unveiled their new collaborative robot Sawyer in March, states that the Baxter SDK v1.1.1 is focused mainly on adding fixes to further stabilize the SDK with ROS Indigo.
The Machine Sync I/O
These changes were partly developed to compliment the Machine Sync I/O addition that came in the previous update: Baxter Research Robot SDK v1.1. The Machine Sync I/O enables a tighter integration of Baxter with other equipment and automation systems already set up, making Baxter deployment easier for its new users.
