Hello Robot Stretch
Hello Robot Stretch is a lightweight mobile manipulator combining a differential-drive base, a vertical lift, and a horizontally telescoping arm with a compliant wrist and gripper. Designed by Hello Robot for research and assistive applications, its slim footprint, low mass, and comparatively low cost made it a popular platform for home manipulation research and benchmarks such as open-vocabulary mobile manipulation.
Why it matters for physical AI
Affordable, safe mobile manipulators lower the barrier to collecting household manipulation data and testing policies in real homes, a setting most industrial arms cannot enter.
Build physical AI
Put these concepts to work on real hardware
Axol is a dual-arm robot built for physical AI — teleoperate it, collect demonstrations, and deploy learned policies out of the box.
