Canonical robot record
Overview
Sawyer is a single-arm collaborative robot introduced by Rethink Robotics, a Boston-based company, to automate precision tasks in manufacturing environments. It was designed to work safely alongside human workers without protective caging, targeting jobs such as machine tending, electronic testing, and small-part handling that were previously difficult to automate cost-effectively.
The robot relies on high-resolution force sensing embedded at each joint, which gives it compliant motion control and the ability to adapt to variability on the production line. An expressive on-board display communicates the robot's intent and status to nearby operators, reflecting Rethink's focus on intuitive, human-friendly automation.
Sawyer first appeared as the successor to Rethink's earlier Baxter robot and was rolled out for global deployment across North America, Europe, and Asia-Pacific. Following the closure of the original Rethink Robotics in 2018, the company's assets and the Sawyer product line were transferred to new ownership.
