About Stretch A mobile manipulator equipped with a 3D camera, an inertial measurement unit (IMU) with 9 degrees of freedom, a LiDAR, an in-vehicle computer, and a thin telescopic arm gripper that replaces a human arm. It is designed to help people work together in home, work, and other settings, such as vacuuming, opening doors, folding laundry, carrying drinks, watering plants, and more. can be done remotely. Hello Robot – Stretch 3 – Product Highlights

The first model Stretch Research Edition (Stretch RE) was released in 2020, and this is the latest model release in about a year since Stretch 2023 was released in early 2.
Stretch 3 update location
Since the launch of the first model, the Stretch Research Edition (Stretch RE), the Stretch series has been constantly updated based on customer feedback.
The latest model, Stretch 3, is equipped with "Dex Wrist", which was an optional part on the 2, as standard, which adds freedom of pitch and roll to the gripper, and a depth camera D405 has been added to the gripper, making it more accurate. allows for flexible operation.
Other improvements include a wide-angle RGB head camera mounted on the head, a mechanism that allows parts to be replaced with a single button, hardware updates, improved computing power, and compatibility with ROS 2 and Ubuntu 22.04, software updates, and features for remote control. Functionality has been improved in various aspects, such as the web interface and support for Embodied AI.

*What is Embodied AI? Embodied AI (embodied artificial intelligence) is a technology that is realized through robots and devices that incorporate sensors and actuators that allow AI to operate and interact in the physical world. This approach aims for AI systems to learn and operate in real environments, not just virtual worlds. Specifically, this means that the robot has the ability to sense its surrounding environment using visual, tactile, auditory, and other sensors, learn from that information, and autonomously decide on appropriate actions. |
