- Weight & Size
Smaller and lighter weight than Baxter (165 lbs without pedestal), Sawyer (42 lbs without pedestal) can maneuver into the tight spaces and varied alignments of work cells designed for humans.
- Humanoid Design
Whereas Baxter is a humanoid robot with 2 arms with 7 degrees of freedom (DOF), a torso and a head, Sawyer only has one arm with 7 degrees of freedom (DOF) and no separate body.
Sawyer can handle a payload of around 8.8 lbs (4kg) versus Baxter who can only handle around 5 lbs (2.2kg) per arm.
Precision & Vision
Sawyer is more precise than Baxter and also has better repeatability, this is partly due to new zero backlash gear boxes and harmonic drive motors being used. As compared to Baxter, Sawyer’s vision system has been improved by a Cognex camera with built-in light source in the wrist for precision vision applications.
Sawyer has been designed and manufactured to be certified for global markets, so companies worldwide can begin using the Sawyer robot.
