Overview
D1 is a fully modular embodied intelligent robot developed by Direct Drive Technology. A single module weighs 24.3 kg and reaches 2 m/s in bipedal mode; when two modules dock, the 48.5 kg quadruped structure reaches 3.2 m/s. It carries 80 kg standing and more than 100 kg prone. The 43.2 V 9 Ah (388.8 Wh) battery provides at least 5 hours of no-load runtime and up to 25 km of range; charging takes under 2 hours. The documented maximum obstacle height is 70 cm, with a recommended operating obstacle of 50 cm. Ubuntu 22.04 and ROS 2 run on an NVIDIA Jetson Orin NX 8 GB; through 2 × USB-C, 1 × Ethernet and a charging port, a robotic arm, depth camera, LiDAR and large wheel modules can be added. Use cases: embodied AI and robotics R&D labs, security patrol and inspection routes, short-distance delivery and logistics experiments, emergency rescue and field robotics testing, robotics filming, demonstration and multi-locomotion research.
Fully Modular Structure
D1 is positioned as the world's first fully modular embodied intelligent robot. A single module runs in bipedal mode at 24.3 kg; when two modules dock, they form a 48.5 kg quadruped structure. Speeds are 2 m/s and 3.2 m/s in the undocked and docked locomotion modes respectively.
High Payload Capacity
It carries 80 kg standing and more than 100 kg in the prone position. This capacity leaves room for add-on modules such as a robotic arm, LiDAR and a depth camera, as well as short-distance logistics experiments.
Runtime and Range
The 43.2 V 9 Ah (388.8 Wh) battery provides at least 5 hours of no-load runtime and up to 25 km of range. Charging takes under 2 hours.
Obstacle Capability
The documented maximum obstacle height is 70 cm; a 50 cm operating obstacle is recommended for safer evaluation. It is designed for multi-locomotion testing.
ROS 2 and Expansion
Ubuntu 22.04 and ROS 2 run on the NVIDIA Jetson Orin NX 8 GB. Through 2 × USB-C, 1 × Ethernet and a charging port, a robotic arm, depth camera, LiDAR and large wheel modules can be added; software is updated via OTA.

About the DirectDrive D1
D1 Frequently Asked Questions
The most commonly asked questions and answers about D1.
Single is one D1 platform and Double is two units. Double is chosen for projects that need parallel testing or collaboration. The specifications give undocked (24.3 kg, 2 m/s bipedal) and docked (48.5 kg, 3.2 m/s quadruped) values separately.
Yes. D1 is built around Ubuntu 22.04 and ROS 2, so research teams can develop navigation, perception and secondary development workflows on the platform.
D1 is designed for multi-locomotion testing. The documented maximum obstacle is 70 cm; a 50 cm operating obstacle is recommended for safer evaluation.
The 43.2 V 9 Ah (388.8 Wh) battery provides at least 5 hours of no-load runtime and up to 25 km of range. Charging takes under 2 hours.
Official expansion options are a robotic arm, depth camera, LiDAR and large wheels; software is updated via OTA. Interfaces: 2 × USB-C, 1 × Ethernet, 1 × charging port.
