Hello Robot Stretch

Hello Robot's lightweight, open mobile manipulator, widely used in home-robotics research.

Stretch is the mobile manipulator made by the US company Hello Robot: a small differential-drive base topped with a vertical lifting column, carrying a horizontally telescoping arm with a wrist and gripper at the end. Rather than aim for a humanoid form, it covers tabletop, floor, and cabinet heights around a home with very few degrees of freedom. The third generation, Stretch 3, released in February 2024, is priced at $24,950, weighs about 24.5 kg, has a footprint of about 33×34 cm, and ships with a DexWrist 3 wrist and a depth camera built into the gripper. Because it is light, inexpensive, and runs open-source software, it has become a common academic platform for home mobile-manipulation research; both OK-Robot and Dobb-E ran their experiments on it.

ExampleOK-Robot used a Stretch to perform open-vocabulary pick-and-place in real homes, such as “bring the object on the table to the specified location.”
