Is Silicon Valley Ready to Welcome Robots into Our Homes? Hello Robot Believes So.

Situated in Martinez, California—distanced from the tech-centric Silicon Valley yet integrated into the San Francisco Bay Area—Hello Robot stands out as a budding startup that champions a more grounded approach to robotics compared to its ambitious counterparts located 45 miles to the south.

Recently, Hello Robot introduced the fourth iteration of its home assistance robot, Stretch. While it presents a somewhat human-like torso and a head equipped with sensors, its extendable arm is fitted with pinchers and it navigates on a robust omnidirectional wheeled base.

As Stretch’s battery levels dip, lights flicker around its “eyes,” prompting engineer Blaine Matulevich to comically observe that “it looks angry.”

Established in 2017 by CEO Aaron Edsinger, a former robotics director at Google, alongside CTO Charlie Kemp, a professor from Georgia Institute of Technology, Hello Robot aims not to create a foundational model or displace human roles. The team tailored Stretch for a significantly overlooked purpose: operating seamlessly within actual homes alongside individuals, rather than being restricted to laboratories.

This focus is vital. Despite the enhancements in artificial intelligence set to improve robotic functionalities, valuable training data remains limited. Additionally, as simulation technology advances, investors increasingly emphasize real-world deployment.

“Companies that deploy first create site-specific recovery loops and workflow tolerances that no rival can replicate or purchase,” highlighted Bullhound Capital in a recent industry report. “In robotics, the competitive edge isn’t solely intellectual property (IP), but the amassed operating hours in real-world conditions.”

A Different Kind of Embodiment

Keith Platt, an investor from Georgia now serving on Hello Robot’s board, became involved following his use of Stretch as a personal assistant. After losing mobility in 2021, retaining control only of his shoulders, neck, and head, Platt commenced exploring adaptive technologies and formed a partnership with Hello Robot in 2024, collaborating closely with an occupational therapist on their team.

Platt operates Stretch using a voice-controlled iPhone application. He can command it to navigate autonomously within his home and take manual control to manipulate items and complete tasks. One notable challenge has been teaching Stretch to serve him a protein shake at breakfast—a task typically necessitating another person.

“Initially, it took me nearly two hours to do that independently—without anyone in the room,” Platt shared with TechCrunch. “But I was determined. Eventually, I succeeded in drinking the entire shake and placing the cup back on the counter in a matter of minutes.”

Reliance on others can represent a significant physical and emotional challenge, according to Platt. Every bit of regained independence—such as putting on or removing his reading glasses or brushing his teeth—“is monumental.” It impacts not just him but also his caregivers.

He believes it could be “life-changing” for families if robotic assistance could empower individuals with mobility limitations to spend their days safely at home, allowing family members to work independently or leave without needing a professional caregiver.

Stretch is designed with limited autonomy straight out of the factory, underlining the necessity of human oversight. “Being in control is a feature—it’s meant to be embodied in the robot,” stated Matulevitch.

Notably, Platt mentions that he is not concerned about Stretch tipping over if it ever makes a mistake.

Hardware is Hard

Despite substantial funding pouring into startups creating the “brains” for robots, their physical embodiments continue to face significant constraints. While components are becoming cheaper, existing technology results in heavy limbs that require considerable energy for balance. Robotic hands and arms are notably heavier than human equivalents, leading to strict physical limitations.

When robots make mistakes, they can inflict damage on nearby objects. For example, The Bot Company is currently embroiled in a lawsuit from an Airbnb host in San Francisco, alleging that their robot caused scratches on furniture, broke appliances, and chipped tiles.

“Presently, the hardware situation is quite dismal regarding the prospect of having robots in my parents’ home,” expressed Mahi Shafiullah, a postdoc specializing in robotic hands at the University of California, Berkeley. He recalled instances in which industrial robots in his lab mistakenly damaged a plastic kitchen play set they were intended to handle delicately.

Shafiullah eventually collaborated with the third generation of Hello Robot’s Stretch during his PhD research at New York University, where the models he developed won the best demonstration award at last year’s Computer Vision and Pattern Recognition (CVPR) conference.

While Hello Robot does not claim that Stretch will match the intricacy of humanoid robots captivating the tech landscape, its simplified design may provide greater efficiency. Edsinger compares his company’s approach to Waymo, which emerged as the frontrunner in self-driving cars by prioritizing safety (albeit with ample financial support).

A noteworthy competitor in the robotics scene, 1X, garnered significant attention last year with the debut of its humanoid robot, Neo, designed for household tasks. The company claims to have sold out its planned production of 10,000 units for this year, but deliveries have yet to commence.

“Hello Robot is very cautious and thoughtful about addressing these challenges, designing it to be safe for human interaction first,” remarked Shafiullah. “Then they consider what capabilities can be integrated within those limitations.”

Homeward Bound

Stretch 4 is offered at a competitive price of $30,000, slightly above robots from Chinese manufacturers, although Edsinger observes that those generally lack included sensors and software, which can ultimately inflate costs. The company plans to produce between 200 and 300 units at its Martinez facility, with the initial batch already sold out.

Edsinger is committed to keeping the robot accessible for researchers and hackers on tight budgets. A critical design requirement for Stretch is its ability to be shipped in a cardboard box via UPS or DHL—costly wooden crates and installation teams compromise accessibility and affordability.

Hello Robot’s customer base includes researchers using Stretch to experiment with advanced AI systems, enterprise clients assessing Stretch’s applicability in environments like data centers, and developers creating in-home assistance for individuals with disabilities.

With its comprehensive sensor suite, physical abilities, and safe operations, Stretch holds promise for those who believe in the potential of physical AI.

“While the algorithms may be available, the data is insufficient—data constitutes roughly 80% of what is essential,” Shafiullah explained.

Having a robot capable of safely collecting that data marks a vital breakthrough. Hello Robot intends to persist in evolving; they aim to apply insights gained from the Stretch 4 launch to future models, potentially lowering costs and enhancing capabilities to realize a vision of home-based robot-human collaboration more effectively.
