Robonix Webots CI Report

All 15 scenarios passed — Soma subsystem integrated and tested

Provider: deepseek · Model: deepseek-chat · Generated On: 2026-07-04T15:28:59+00:00 · Stage: success · Confidence: high

This PR introduces the Soma subsystem (robonix-soma), a raw body YAML and URDF service that also owns primitive and skill package bring-up in two stages. All 15 Webots CI scenarios passed, covering builtin file operations, plan control, camera/lidar snapshots, exploration, mapping, memory, speech, voiceprint, scene object listing, fault recovery, object navigation, and patrol observe. The Soma service registered successfully, spawned 4 primitives (tiago_chassis, tiago_camera, tiago_lidar, audio_driver) in stage 1 and 1 skill (explore) in stage 2, and Pilot fetched Soma context at startup.

PR Changes

Added new system/soma crate with config, deployment, launcher, service, store, and report modules
Added capabilities/system/soma/get_yaml and get_urdf contracts with IDL
Added examples/test_ci/soma.yaml and test_ci.urdf for testing

Modified system/atlas/src/service.rs (minor formatting change)
Modified system/pilot/src/main.rs, planner.rs, service.rs to fetch and inject Soma context into system prompt
Added system/pilot/src/soma_context.rs for fetching YAML/URDF from Soma
Modified tools/rbnx/src/cmd/deploy.rs with soma spawning, stage-2 pipe, and ensure_soma_defaults
Modified tools/rbnx/src/cmd/clean.rs and run_package.rs to include soma in builtins list
Added tools/rbnx/src/launch.rs with shared package bring-up primitives (wait_for_registration_core, call_driver_cmd)
Modified tools/rbnx/src/lib.rs to export launch and pb modules
Modified tools/rbnx/src/process.rs to add process_group(0) and state save/remove
Modified tools/rbnx/Cargo.toml to add nix fs feature

Test Result

Webots CI ran 15 scenarios (4 builtin, 7 cap, 4 flow) against a full system boot with atlas, executor, soma, pilot, liaison, scene, memory, speech, voiceprint, mapping, nav2, and explore. All 15 passed. Soma stage 1 spawned 4 primitives (tiago_chassis, tiago_camera, tiago_lidar, audio_driver) and stage 2 spawned 1 skill (explore). Pilot loaded Soma context at startup. Navigation succeeded to a potted plant approach pose. Exploration timed out as expected (5s and 8s ceilings).

Suggested Fix

No fix needed. Monitor scene-graph-llm request failures (fake-vlm returns empty responses) and nav2 'Failed to make progress' during object navigation — these are known CI environment limitations, not regressions.

Risks Or Watchouts

Scene-graph-llm requests to fake-vlm return empty responses (Expecting value: line 1 column 1) — scene graph relations will be empty until a real VLM is configured.
Nav2 controller_server logged 'Failed to make progress' during object navigation to potted plant, but the navigation eventually succeeded after replanning.
Voiceprint list returned 'db not initialised' — expected in CI with ephemeral storage.
Soma stage 2 trigger uses a blocking read on a raw fd; if rbnx closes the pipe early, skills won't start.
