D-Robotics raises $400 million for robot chips and software

Funding a supplier to robot builders

D-Robotics announced a $400 million Series C financing on September 17 in a company release distributed by PRNewswire. The company intends to develop its Sunrise chips alongside software covering data collection, training, simulation, inference and deployment. TechNode reported the announcement the following day.

The company reports cumulative Sunrise shipments above eight million, several-fold revenue growth in the first half of 2026, and adoption of Sunrise S600 by more than 20 customers within six months of its November 2025 launch. It does not disclose a revenue amount, valuation or investor allocation.

An ecosystem beyond a single robot design

The release names S600 customers including UBTECH, Astribot, FOURIER and Booster Robotics. It also describes the Gravity Program, which supports companies with development, supply-chain selection and commercialization. D-Robotics says the program has backed more than 500 innovators across ten categories. These are company-reported relationships and program figures, not a breakdown of contracted chip revenue.

Serving multiple robot categories spreads the platform across different use cases, but also creates engineering demands. A home companion, an industrial mobile robot and a humanoid do not necessarily share the same sensor interfaces, power budget or task timing. A broad portfolio is useful only if the software and support make those differences manageable for customers.

What developers can evaluate today

D-Robotics’ English resource center lists the RDK S600 developer kit with a specified 560 TOPS of AI inference capability and an 18-core Arm Cortex-A78AE processor. It also lists the smaller S100 at 80 or 128 TOPS and six CPU cores, alongside X3 and X5 boards. Those are product specifications, not measured robot-task success rates; TOPS cannot by itself compare a complete robot’s capability.

The same site supplies a Model Zoo, application examples and separate model-deployment toolchains. Its OpenExplorer toolchain covers the development lifecycle, while S-series language-model tools address deployment on the corresponding boards. Developers can begin with an existing kit and documented tools rather than waiting for the financing to produce a new chip.

A separate software FAQ describes TogetheROS.Bot as a ROS 2-based environment adapted to RDK hardware, including drivers and acceleration libraries. It warns that packages compiled for an x86 computer cannot simply run on an Arm board. Software compatibility therefore includes processor architecture and operating-system version, even when applications use the same robotics messaging framework.

This is a concrete part of the hardware-and-software proposition behind the round: a model, its conversion tools, board drivers and robotics middleware must work together. The available documentation shows where a developer starts that evaluation. It does not establish the price, production allocation or support terms of a customer’s eventual embedded design.

What the shipment figure does and does not show

Eight million cumulative chips should not be read as eight million new humanoid robots. The report describes shipments across the Sunrise portfolio, without breaking them down by product, period or end use. Likewise, customer adoption of S600 does not reveal the production volume of each customer.

The company release verifies the financing announcement, while its operating figures remain self-reported. A fuller commercial assessment would require product-level shipment data and repeat production orders. The Series C supplies resources to build that business; the release does not establish its profitability or the volume represented by each named customer.
