Soft Robotics Inc., which makes robotic grippers inspired by octopus tentacles, has raised $3 million in Series A funding. The company, which won a Game Changer Award for best gripper at this year’s RoboBusiness conference, expects to add another $2 million soon.
Cambridge, Mass.-based Soft Robotics was spun out of Harvard University’s Whitesides Research Group in 2013. The U.S. Department of Defense provided the initial funding for flexible surgical tools, but the robotic grippers turned out to be better suited for other tasks.
The company’s soft fingers are filled with compressed air and can handle a variety of objects without damaging them. This is particularly useful in warehouses and in dealing with clothing, electronics, or fruits and vegetables.
“We’ve really hit on this unmet need of, ‘How do we enable robots to handle things that vary in size and shape and weight?’ There’s pent-up demand,”‘ said CEO Carl Vause. “There’s a reason the squid, the octopus, and the human hand work so well.”
Four customers have completed pilot testing and are beginning to use Soft Robotics‘ grippers in production.
One benefit of Soft Robotics’ flexible end effectors is that they can be easily sterilized for compliance with food-safety regulations. Leamington, Ontario-based Nature Fresh Farms is looking Soft Robotics hands for handling tomatoes.
This past summer, Soft Robotics partnered with Heinzen Manufacturing International, which makes equipment for packaging produce for shipment to grocers. Gilroy, Calif.-based Heinzen Manufacturing also works with robotics manufacturer Yaskawa Motoman.
“We’re excited to have investment partners who bring much more than capital to the company,” said Vause. “China is the fastest-growing robotics market in the world, and we’re proud to work with Haiyin Capital as we expand geographically. Having Taylor Farms on board brings world-class leadership and expertise in the produce industry, where we are currently deploying systems to meet the growing demand for process automation.”
Soft Robotics expects to double its staff of five people and scale up to meet demand.
A soft touch
As robots move into applications such as healthcare and logistics where they increasingly interact with humans, soft robotics are expected to make them more flexible and useful.
The development of soft grippers allows robots to handle multiple and fragile objects without having to change out end effectors.
Other researchers are working on similar grippers, including Rob Scharff, a graduate of the Delft University of Technology and a team at MIT’s Computer Science and Artificial Intelligence Laboratory.

Earlier this year, Grabit Inc. in Santa Clara, Calif., released its P-Series grippers. They use “electroadhesion” technology that uses static electricity for a variety of applications, including parts and package handling and picking circuit boards and fabric.
Brooklyn, N.Y.-based prototyping company Super-Releaser this week described a 3D-printed soft robotic gripper to demonstrate the technology’s potential.
