Direct Drive Tech D1

What it's for

The D1 from the Chinese company Direct Drive Tech (DDT) is a modular "embodied intelligence" robot whose individual modules can be physically joined into two-legged, four-legged or swarm forms; it rolls on wheels across a hall and stands on "legs" over rough ground. The manufacturer calls this technology "All-Domain Splicing". In four-wheel mode the D1 carries up to 100 kg, up to 80 kg when standing, has a range of over 25 km unloaded and works for more than 5 hours in the standard wheel-leg mode; the drive uses direct-drive motors, meaning motors that deliver torque straight to the joints. The stated audience is research and industry. In a laboratory the D1 is a platform for experiments with configuration, gait and the teamwork of many units; in a factory the catalog lists industrial uses, but there are no confirmed deployments. The D1 is not a humanoid in the strict sense, although the manufacturer says it can "form itself" into a humanoid-like configuration. For more on how legged robots work, see “How Does a Humanoid Robot Work”, and for drive systems, “Actuators in Humanoid Robots”.

Who it's for

Makes sense for: research teams and industrial companies that experiment with modular robotics and can handle integration on their own, such as universities, laboratories and R&D departments. A payload of up to 100 kg and a 25 km range are interesting figures for this class. Who it does not suit: a buyer who needs a price, a datasheet and a distributor. The manufacturer publishes neither a price nor a full specification of weight and dimensions, and there is no confirmed distributor in Poland. For an unprepared integrator that means high risk: no documentation, no service, an unclear certification status. Polish companies looking for something ready to work alongside people should look at the humanoid robots or quadruped robots sections. If the modular concept interests you, treat the D1 as a sign of a trend, not as a purchase proposal.

Deployments

The D1 is a freshly unveiled product, and we have no customer list. What exists in nearby categories? Industrial quadrupeds such as the Unitree B2 work in facility inspection, AMR robots from the mobile robots section haul loads in warehouses, and an overview of real factory applications is in “Humanoid Robots in Factories 2026”.

GITAI G1 is a torso-type humanoid robot for space work, a completely different path: instead of modularity it bets on a human-like torso and work in extreme conditions. Dusty Robotics FieldPrinter is a construction robot that prints wall layouts on the floor, a concrete industrial application if you are looking for a task rather than a configuration. Boston Dynamics Stretch is a proven warehouse robot for unloading; choose it when you need dependable performance in logistics. Unitree B2 represents industrial quadrupeds with real availability, and MiR250 is an autonomous transport robot from the well-regarded MiR family. None of them joins into a swarm, but each has what the D1 lacks: a datasheet and a supplier. If modularity matters to you, watch the D1; if working results do, pick something from this list.

The D1 was unveiled in October 2025. We know of it mainly from industry reports; the only spec sheet available is an article from the portal robohorizon.com from the same month, not an official manufacturer datasheet. Direct Drive Tech is a Chinese company for which we have no founding year, city or funding information, and its manufacturer profile is flagged as needing further source verification. We therefore know of no earlier generations or later versions of the robot. It is a young product and needs patience: only the coming months will show whether the modular concept moves beyond a presentation.
