California-based robotics company Hello Robot is pushing home robots into more specific applications. TechCrunch reports that the company released its fourth-generation assistive robot, Stretch, last month. Its focus is not on a humanoid appearance, but on integrating it into real homes to help people with disabilities complete daily tasks.
Focusing on home assistance scenarios
Stretch 4 does not follow the typical humanoid robot route common in Silicon Valley. It uses a wheeled base, telescopic robotic arm, and gripper structure, and is equipped with multiple sensors, emphasizing stability, operability, and safety performance in the home environment.
Hello Robot was founded in 2017 by Aaron Edsinger, former head of Google's robotics business, and Charlie Kemp, a professor at Georgia Institute of Technology. Instead of betting on a "general-purpose robot" narrative, the company focuses on tackling specific tasks within the home.
For users with mobility impairments
The report mentions that Keith Platt, a director and investor at the company, became quadriplegic in 2021 due to an injury. He subsequently began using assistive technology and partnered with Hello Robot in 2024. He can now control Stretch to move around his home via an iPhone voice app and then take over the robotic arm to perform specific actions.
Taking the preparation of a breakfast protein shake as an example, the entire process initially took nearly two hours, but after repeated training, it has been shortened to just a few minutes. Actions such as putting on glasses, brushing teeth, and picking up and putting away items have also become key scenarios for robot assistance.
Safety first, then capabilities.
Hello Robot has not yet made Stretch fully autonomous. The company intends to retain a "human-in-the-loop" control approach, allowing users to remain in control during key actions to reduce the risk of misoperation. This is also a major difference between it and many other humanoid robot startups.
The article points out that current robot hardware still generally suffers from problems such as large weight, high energy consumption, and difficulty in balancing; if a mistake is made, it can easily damage surrounding objects. In contrast, devices with simpler structures are more likely to be introduced into the home environment first.
Price: $30,000
The Stretch 4 is priced at approximately $30,000. While this isn't cheap for consumer electronics, it's relatively affordable for a robotics product. Edsinger stated that the company planned to produce 200 to 300 units at its Martinez headquarters, and the initial production capacity has already sold out.
The company also aims to lower the barrier to deployment. One of Stretch's design goals is to be able to be directly boxed and shipped via UPS or DHL, without relying on wooden crates and on-site installation teams. Current customers include research institutions, enterprise users testing data center scenarios, and teams developing home assistance solutions.
