Hello Robot Stretch 4 added to the catalog

Hello Robot's open-source mobile manipulator joins HomeBotRadar with confirmed $29,950 pricing, 8-hour runtime, and a research-certified buy path.

We added Hello Robot Stretch 4 to HomeBotRadar. It is a wheeled mobile manipulator with a telescoping arm, omnidirectional base, and sensor-rich navigation built for assistive home pilots and embodied-AI development.

Our profile at Stretch 4 covers official datasheet specs (160 cm height, 46 kg, 8 h battery, 2.5–4 kg payload) and the $29,950 purchase page at hello-robot.com. Hello Robot ships now but certifies Stretch 4 for laboratory and research use while in-home assistive pilots continue.
