TechCrunch Disrupt 2026: Aaron Edsinger brings Hello Robot’s Stretch 4 onstage

Robots that walk, talk, dance and do backflips make great video. The harder question is whether they can close the blinds, help someone eat or scratch an itch — for people with severe mobility impairments, those everyday tasks can mean real independence.

At TechCrunch Disrupt 2026, Hello Robot CEO and co-founder Aaron Edsinger will bring Stretch 4 to the Real World AI Stage for a session titled “Come, Meet Stretch. The Robot Built for Real Life, Not a Demo Reel.” The live demo takes physical AI out of the lab and shows what becomes possible when usefulness, safety and accessibility drive robot design.

The timing is notable: Stretch 4 launched in May, and its first production run had already sold out when TechCrunch spoke with Edsinger in June. While much of the robotics industry chases humanoids, Hello Robot built a compact wheeled robot with a telescoping arm for human spaces.

What does it take to build a useful robot?

Stretch 4 doesn’t need legs; it rolls. It doesn’t need two arms; a single telescoping arm grabs and manipulates objects, while onboard sensors, perception and contact sensitivity let it work safely around people. That shows in what users do with it: people with severe mobility impairments can feed themselves, close blinds or scratch an itch. TechCrunch recently profiled a user with quadriplegia who used Stretch to drink a protein shake, handle his glasses and brush his teeth.

Meet the roboticist behind Stretch

Aaron Edsinger has spent his career building robots designed to work with people. Before co-founding Hello Robot, he founded Meka Robotics and Redwood Robotics, two companies acquired by Google in 2013, where he later led development of two central robotics investments. At Hello Robot the goal is not the most human-looking machine but one people can actually use: Stretch 4, the company says, was shaped by six years of customer feedback and ships with an open source platform for robotics and embodied AI research.

More than 200 sessions and 10,000+ people at Disrupt

The demo is one stop in three packed days: Disrupt runs October 13–15 at Moscone West in San Francisco, with more than 10,000 founders, investors and tech leaders expected, 200+ sessions, 250+ speakers and 300+ exhibiting startups. Passes cost up to $200 less before September 25 at 11:59 p.m. PT.
