Direct Drive Tech (DDT)

Little is known about Direct Drive Tech (DDT), and that has to be said plainly. The company is Chinese, has the website ddtai.com, and according to the description in our listing deals with direct-drive motors and modular robotic platforms. The founding year, headquarters and funding history are not given. What is documented comes mainly from one text: in October 2025 the portal RoboHorizon described the D1 model as “the world's first fully modular embodied-intelligence robot”. The technology the manufacturer calls “All-Domain Splicing” allows individual units to be physically joined into bipedal, quadruped or wheel-legged configurations, or into larger swarm assemblies. So there is no classic company story with investment rounds here, just an announced product and an ambition. We don't guess the rest. If the manufacturer publishes corporate documents, we will supplement this section, and for now we treat the entire entry as a cautious profile based on a single, though substantive, source. For the record, the description of the company comes from its own materials and one independent portal, not from financial reports, so every claim, whether range, payload or runtime, must be read as the manufacturer's claim. We recommend similar caution with any Chinese manufacturer that the media write about right after a launch, before independent tests appear.

The portfolio has one model: Direct Drive Tech D1. It is a modular robot that in four-wheel mode carries up to 100 kg, in a standing posture up to 80 kg, has a range of more than 25 km unloaded and runs for more than five hours in the standard wheel-leg mode. The drive is based on gearless (direct-drive) joints, and the manufacturer emphasizes the ability to join units together. The D1 is not a humanoid in the strict sense, which is why it sits in the “other” category in our listing; it is closer to specialist robots than to humanoid robots. The manufacturer gives no weight or dimensions, and what such a gap means is explained in “How to Read a Robot Datasheet”. Drives and joints are covered in “Actuators in Humanoid Robots”. The term “direct drive” means the motor acts on the joint without a gearbox, which simplifies the mechanics and improves force sensing but requires powerful motors. This solution explains why the manufacturer can talk about range and payload in one description, although without a price and dimensions it is hard to judge cost-effectiveness. The applications the manufacturer indicates are research and industry.

DDT's market position cannot be judged reliably today. We have no data on funding, valuation, stock listing, number of customers or headcount. Comparisons are possible only at the level of concept. Classic humanoids with a fixed form, such as the Unitree G1 from Unitree Robotics or the Figure 02 from Figure AI, have a single configuration and detailed specifications. Quadruped robots, for example the Unitree Go2-W, are specialized in one type of movement. The D1 bets on flexibility: one platform, many shapes. The advantage of this approach is versatility, the drawback the lack of confirmed deployments and of a price. As things stand, the company is more a technological curiosity than a competitor to established players. It is also worth noting that the company's name refers to motors, not whole robots, which shows its roots in components. Anyone assessing it as a supplier should also compare drive suppliers from our section “Robotics Glossary: 65 Terms with Polish Equivalents” and available components, for example CubeMars or MyActuator.

In Poland the D1 is not available, and no confirmed distributor has been found. There is also no Polish research project using it. Because the manufacturer targets research and industry, the natural recipients would be Polish technical universities and laboratories, but no documented offer for them exists. People looking for a robot for classes and research will find hints in the article “Educational Robots for Schools and Universities”, and available quadruped platforms are described in “Quadruped Robots: Uses in Inspection, Security and Industry”. Until a distributor appears, it is sensible to use locally available components, described in the components section.

The DDT D1 is a bold idea for a modular robot, but for now it rests on a single source and has no confirmed price, dimensions or availability. For laboratories: worth following. For companies looking for a tool to work with in Poland: still too early. We don't rule out that the assessment will change with further publications. When independent tests, a price and a partner in Europe appear, we will update the assessment, and until then we are keeping a cautious stance.
