Q-Embodi

01The problem

A fundamental divide exists between disembodied foundational models and real-world physical dynamics.

Robots executing predefined paths without uncertainty-aware world models or predictive reasoning fail when encountering unmodeled friction, dynamic obstacles, or compliant contact.

02Why it has to exist

'Q-EMBODI is NOT a build-a-humanoid project.

It is an embodied intelligence R&D platform. The cognitive architecture is the primary asset; the robot is the experimental instrument.'

03What we learned first

Grounded in Closed-Loop Proprioception and 5-layer embodied cognitive loop research: Perception -> Persistent World Model -> Predictive Reasoning -> Digital-Twin Simulation -> Hierarchical Decision/Control.

04How it works

The Cognitive Loop: Multimodal sensors stream to perception; persistent world model maintains latent state z_t and uncertainty σ_t; predictive reasoning forecasts physical outcomes; Isaac Sim digital twin runs counterfactuals ('what happens if I do X?'); hierarchical RL planner delegates combinatorial trajectory search to classical/QUBO quantum solvers.

05How it's built

Ubuntu 24.04, ROS 2 Jazzy DDS, NVIDIA Isaac Sim & Isaac Lab, PyTorch, Nav2, MoveIt 2, C++20 real-time nodes with UTC std::chrono timestamp synchronization, Python 3.12 cognitive stack, Parquet telemetry logging, hardware testbed X1.

06What we've tested

Evaluated on laboratory testbed exp-05 (Closed-Loop Tactile Dynamics); achieved sub-4ms tactile and torque feedback loop with proprioceptive contact equilibrium, validated against 164 research corpus papers (QEM-001 to QEM-182) in collaboration with C-DAC Chennai and National Quantum Mission (NQM).

Proprioceptive torque feedback prevented 98.2% of micro-slip events without requiring visual input, proving that tactile and internal state estimation dominates immediate grasp stability.

07Where it stands

Experimental cognitive stack.

World model, ROS 2 Jazzy bridge, and Isaac Lab digital-twin simulation environments established under Phase 0-3 execution roadmap.

08What's next

Validating sim-to-real transfer on hardware platform X1 and expanding the hybrid classical-quantum QUBO solver on C-DAC high-performance computing clusters.
