en.Wedoany.com Reported - Hello Robot has released the fourth generation of its home assistance robot, the Stretch 4. The robot features a wheeled base, a telescoping arm, and a gripper, along with a sensor-equipped head, enabling it to move and perform manipulation tasks in home environments.
Hello Robot was founded in 2017 by former Google Robotics Director Aaron Edsinger (CEO) and Georgia Institute of Technology Professor Charlie Kemp (CTO). The company focuses on developing robots that can collaborate with users in real home environments, rather than building general-purpose artificial intelligence models or replacing all human tasks. Currently, most robotic products remain confined to laboratory settings, and the lack of training data in home scenarios is considered a major bottleneck for industry development. In a recent report, Bullhound Capital noted that early-deploying companies can accumulate site-specific recovery processes and operational tolerances, and this real-world operational data constitutes a barrier that competitors find difficult to replicate.
Keith Platt, an investor from Georgia and a member of Hello Robot's board of directors, became quadriplegic after an accident in 2021. He then began exploring assistive technologies and came into contact with the company. Using a voice-controlled iPhone app, he commands the Stretch to perform autonomous navigation and object manipulation. Platt stated that initially, completing the task of independently retrieving a breakfast protein shake took nearly two hours, but with repeated practice, the time was reduced to just a few minutes. He believes that the ability to independently perform daily actions such as putting on glasses or brushing teeth is "life-changing" for individuals with mobility impairments and their families. The Stretch comes with limited autonomous functions out of the box, emphasizing human-in-the-loop control, and its design team includes occupational therapists.
The robotics hardware sector still faces challenges related to weight, energy consumption, and safety. Mahi Shafiullah, a postdoctoral researcher at the University of California, Berkeley, pointed out that current hardware is difficult to deploy safely in homes. During his doctoral research at New York University, he used the third-generation Stretch and developed a model using this platform that won the Best Demo Award at the Computer Vision and Pattern Recognition (CVPR) conference. Shafiullah added: "The algorithms may exist, but the data does not, and data actually accounts for about 80% of the critical component."
Hello Robot CEO Edsinger likens the company's strategy to that of Waymo, prioritizing safety. The base order price for the Stretch 4 is $30,000, which is higher than some products from Chinese manufacturers, though the latter typically do not include sensors and software. The company plans to produce 200 to 300 units at its headquarters in Martinez, with the initial batch already sold out. The robot's customer base includes researchers, enterprise users (e.g., for data center environment testing), and developers of assistive technologies for people with disabilities.
One of the design criteria for the Stretch 4 is that it can be shipped via courier, avoiding cost increases associated with wooden crates and on-site installation teams. Edsinger stated that the experience gathered during the current product iteration will be used to develop the next generation of robots, with the goal of further reducing prices and enhancing capabilities, ultimately achieving human-robot collaboration in home environments.
