One external brain,
any robot.

The 4D Backpack — a plug-and-play external brain for robots. 500g unfelt payload, 10-minute deployment: existing general-purpose robots understand speech, see the environment and execute complex tasks — no in-house algorithm team needed.

Why

Robot intelligence shouldn't wait a cycle

Traditional upgrades walk through hardware, drivers, algorithms and debugging one by one; the 4D Backpack compresses that chain into "boot and go".

Traditional Integration

The full chain, redone for every robot
  • Pick hardware
  • Configure drivers
  • Tune algorithms
  • Integrate & debug
  • Deploy
Deployment cycle: weeks / months — cost and risk stack up linearly with every model

4D Backpack Mode

Plug & Play + Preloaded Skills

Unified API · auto-detected drivers · preloaded AI skill library
  • Power on
  • Connect
  • Core skills auto-load
  • Ready
Deployment cycle: 10 minutes — vision, voice and navigation base models ready out of the box, effective the moment you connect
Architecture

One backpack, three layers

Swap the body freely — the backpack stays the same brain.

LAYER 101

Any Robot BodyBody-agnostic

Quadrupeds, wheeled, humanoid, tracked, drones — ROS2 and mainstream protocols, compatible with 90% of robots on the market. Change the body, keep the backpack.

LAYER 202

Backpack BrainWorld Model × Autonomous Agent

The world model fuses LiDAR / vision / voice to read environment and task, rehearsing physical consequences before acting; a safety loop brakes in 0.1s even offline. 17.6 TOPS local compute + cloud training; sensor redundancy holds under glare and noise.
