Picture a typical factory robot in your head and you'll probably see a cold, unsympathetic arm performing relatively simple tasks. You may want to shake that image soon, though. Rethink Robotics has taken the wraps off of Sawyer, a smaller sibling to its earlier Baxter model that's built for handling high-precision tasks that most machines can't tackle, such as testing circuit boards. The one-armed robot is designed to be as people-friendly as its predecessor, with a touchscreen for a face and software that lets you teach it by guiding it with your hands. The big improvements are in the arm itself. Sawyer is using new actuators and joints that make it smaller, faster and more precise, which should help with assembling or verifying lots of tiny parts.
