Rethink Robotics Sawyer

Rethink Robotics' 2015 single-arm 7-DOF collaborative robot arm.

Sawyer is the single-arm collaborative robot Rethink Robotics released in 2015, following Baxter. It has 7 degrees of freedom and a 4 kg payload, and is smaller, faster, and more precise than Baxter, while keeping the same screen-based head and Intera graphical programming software, plus support for kinesthetic (hand-guided) teaching. After Rethink Robotics shut down in 2018, the German HAHN Group acquired the intellectual property and trademarks for Sawyer and Intera and continued developing and selling them. In robot-learning research, Sawyer was a common arm in labs such as Berkeley and Stanford in the late 2010s, and appears in datasets and benchmarks such as RoboNet and Meta-World, where the simulated arm model is Sawyer's.

ExampleAll 50 manipulation tasks in the Meta-World benchmark — opening a drawer, pressing a button, and so on — are defined on a simulated Sawyer arm.
