AI Summary
- •Hello Robot released Stretch 4, an open-source robotics platform featuring a telescoping arm, omnidirectional base, and sensor array with two hemispherical 3D LiDAR sensors, three high-resolution cameras, and six laser line sensors. The arm, lift, and base operate at twice the speed of Stretch 3, and total reach has been extended by 10%.
- •Stretch 4 prioritizes human-robot safety through a compact, low-potential-energy design and 'sensor-rich' architecture (following a philosophy used by Waymo in autonomous driving) rather than minimalist vision-only approaches. An Nvidia Jetson Orin NX runs Physical AI models on the robot, and an all-new power system enables up to eight hours of runtime with autonomous self-charging via a docking station.
- •The platform has been piloted to support individuals with severe mobility impairments, who control the robot through a mobile phone app to accomplish tasks such as fetching water, closing blinds, and feeding themselves. Since Hello Robot launched the first Stretch in 2020, more than a thousand users from 23 countries have worked with the platform.
- •Stretch 4 is available for purchase today for $29,950 at www.hello-robot.com.
