Hello RobotOpen-source mobile manipulator with telescoping arm and omnidirectional base, built for assistive home pilots and embodied-AI research.

About Stretch 4
Stretch 4 is a wheeled mobile manipulator from Hello Robot, founded by MIT and Georgia Tech veterans Aaron Edsinger and Charlie Kemp. Instead of humanoid legs, it uses a compact omnidirectional base and a telescoping arm so it can reach countertops and work safely beside people in real homes.
Hello Robot ships Stretch 4 ready to run with ROS 2 and Python SDK, reference autonomy demos, and a global developer community. The sensor stack includes two hemispherical 3D LiDAR units, three high-resolution cameras, and six laser-line floor sensors for cords, rugs, and drop-offs. An optional NVIDIA Jetson Orin NX runs physical-AI models on board.
You can order Stretch 4 today for $29,950 with typical ship lead of two to four weeks. Hello Robot notes the platform is currently certified for laboratory and research use while the team runs in-home assistive pilots — including users with severe mobility impairments — ahead of a future consumer assistive product.
HomeBotRadar tracks Stretch 4 because it is one of the few buyable platforms explicitly aimed at home assistance, not just factory floors. Compare it with EBO X for rolling home guardians, Reachy 2 for open humanoid research, or ElliQ if you need a plug-in elder-care companion today.
