OK-Robot evaluates open-vocabulary mobile manipulation on Stretch
Evidence notes
- OK-Robot combines vision-language object detection, navigation, and grasping modules for training-free pick-and-drop tasks.
- The authors evaluate the system in 10 real-world home environments using a Hello Robot Stretch platform.
- The paper reports a 58.5 percent success rate on open-ended tasks and higher performance in cleaner, less cluttered settings.
Company context
Hello Robot builds Stretch, a lightweight open-source mobile manipulator designed for researchers, developers, application engineers and assistive robotics use. The company focuses on practical human-centered mobile manipulation rather than humanoid form factors, with hardware designed for homes, labs and workplaces.
