Think of a warehouse robot and a huge, cumbersome machine probably comes to mind. They're reliable, but difficult to reprogram if you're not a trained specialist. Rethink Robotics is trying to tackle the problem with Sawyer, a one-armed robot with a tablet for a face. A new software update called Intera 5 means it's now easier to program for new, custom tasks in the workplace. At its core is a "behavior engine" that can be visualised like a logic tree. Similar to basic coding applications, that makes it easier for people to change specific movements and 'if this, then that' style reactions.
