Our Verdict: The most practical mobile manipulator for home assistance research. Purpose-built design for domestic environments sets it apart.

The Hello Robot Stretch RE2 is a compact, lightweight mobile manipulator designed from the ground up for assistive and home environments. Unlike industrial arms bolted onto mobile bases, Stretch was purpose-designed with a telescoping arm, dexterous gripper, and slim profile that navigates doorways and tight home spaces with ease.

With full ROS2 support, pre-built manipulation and navigation packages, and an active research community, Stretch RE2 is the leading platform for home assistance, elderly care, and accessibility research. Its affordability relative to other mobile manipulators has accelerated adoption in universities worldwide.
