Direct Drive Technology · Quadruped · 2025
The D1 from Hong Kong's Direct Drive Technology is billed as the world's first fully modular embodied-intelligence robot. Two wheel-legged biped units (24.3 kg each) dock via a central magnetic coupler to form a 48.6 kg wheel-legged quadruped 'robot dog', then separate again autonomously - a capability the company calls 'All-Domain Splicing'. Each unit runs an NVIDIA Jetson Orin NX (8 GB) on Ubuntu 22.04, powered by a 43.2 V / 9 Ah battery good for over five hours, and can roll at up to 11 km/h or walk over rough terrain. Combined, the quadruped carries up to 100 kg (80 kg when standing), with a 25 km empty-load range, targeting security patrol, last-mile delivery, search-and-rescue and mobile filming. A single biped unit is US$7,499; the two-unit quadruped is US$13,999.
