NANJING 4D VECTOR TECHNOLOGY CO., LTD.

Embodied intelligence,
keeping every light on.

We build the brains and souls of robots — and the robots themselves.
At the core is the AI for Decision brain — moving robots from execution to autonomous decision-making.
That brain has grown into two complete machines — Xiaoman, a companion for the elderly, and Argus1000 on 10 kV live lines — and three products: the 4D Backpack, voice service and the 4D Chassis.

a brain that thinks.

Most embodied robots today focus on perception and motion control, with tasks assigned manually. We place the decision brain at the top of embodied intelligence — fusing large models, multi-objective trade-offs and scenario simulation to complete task planning, option rehearsal and risk assessment before execution — moving robots from execution to autonomous decision-making.

01 / SENSE

Perception

Multispectral, RGB, TOF and LiDAR point-cloud fusion reconstructs the environment in 3D, with pose accuracy of ±2 mm.

02 / COGNIZE

Cognition

Scene understanding and task cognition fused with large models — seeing the environment, and understanding the task and its constraints.

03 / DECIDE

Decision

Multi-objective trade-offs and scenario simulation: planning, rehearsal and risk assessment before execution — autonomously weighing cost, risk and priority.

04 / EVOLVE

Self-Evolution

Field perception feeds back into the decision brain; strategies keep iterating — the robot grows smarter with use, beyond a mere execution tool.
