From 4f512cf514c5474aadef6a3608ab3caf66589d46 Mon Sep 17 00:00:00 2001 From: Mario Garrido Date: Tue, 19 May 2026 20:25:24 -0700 Subject: [PATCH 01/20] feat(memory2): Space raster backend + experimental LangChain agent Adds a cv2-based raster renderer for `dimos.memory2.vis.space.Space` so maps can be sent as PNGs to vision LLMs, alongside the existing SVG + Rerun backends. New Space elements (Polygon, Wedge, RasterOverlay) and Point shape/halo variants cover the agent's overlay needs. `dimos.memory2.experimental.memory2_agent` is a LangChain agent that uses the new rendering surface to answer questions about a recorded memory2 SqliteStore (occupancy maps, FOV cones, room polygons, image recall). Tests are gated behind a new `experimental` pytest marker so they don't run by default.

The recording is a moving camera, so the same object is typically visible from multiple angles across multiple frames; naively counting sightings double-counts.

The trick +to counting *uniquely* is not to compare sightings against each other — +that's slow and error-prone — but to **pin each sighting to a world (x, +y)** using a visual feedback loop, then **merge any sightings whose +pinned positions land on top of each other**. + +The loop, per candidate sighting: + +1.

Look at the projected frames: does the red cross land **on the + target's body** in the frames where the target is visible? + - **Yes** → (x, y) is correct for this object. Lock it in. + - **No, the cross is offset** → adjust (x, y) and call + `frames_facing` again. Repeat until convergence (usually 1–3 + iterations). + - **No frames show the target where the cross lands** → either the + sighting was a hallucination, or the position is far enough off + that no covering frame can see it.

A room with `n == 1` has `area_m2 = + None` — flag those as "extent unknown from this sample" in your + final answer rather than calling them zero-sized. + + The bbox from sampled poses is a *lower bound* — the robot may + have entered the room from one side and only walked part of it. + Refine it visually in the next step. + +5. **Look at the map and propose final room POLYGONS.** + Call `show_map(when="now")` and look at the lidar-derived + occupancy. Use your `summary` from step 4 as a STARTING POINT and + then **trace each room's walls**, recording the (x, y) of every + corner where the wall changes direction. + + Four hard rules: + + - **The world frame is NOT aligned to the room walls.** The SLAM + coordinate system started wherever the robot booted; the + building's walls run at whatever angle they happen to. Do not + assume rooms are axis-aligned. Even a simple quad room is + usually a rotated parallelogram in world coords — its corners + will have DIFFERENT y-values on the same wall and DIFFERENT + x-values on the perpendicular wall. + + - **Don't submit an axis-aligned bounding box.** If your + polygon is `[[x_min, y_min], [x_max, y_min], [x_max, y_max], + [x_min, y_max]]`, you've drawn a rectangle around the room's + bounding box, not the room. STOP and re-look at the map — the + walls do NOT go straight up/down/left/right in world coords. + + - **Trace the walls, corner by corner.** Pick one corner of the + room on the map. Read its (x, y) by eye from the show_map + grid. Walk along the wall (visually) to the NEXT corner — note + that this corner's x and y are almost certainly BOTH different + from the previous one, because the wall is at an angle. + Continue around the room. 4 corners for a true quadrilateral + (rotated rectangle = parallelogram); 5–8 for L-shapes or + rooms with alcoves. + + - **Rooms must NOT overlap.** Where two rooms meet (a doorway, + an archway), pick a single line on the map and let each + polygon end at that line. Adjacent polygons share an edge, + never an interior. + + Express each room as: + `polygon = [[x1, y1], [x2, y2], [x3, y3], ...]` + (3+ corners, world coords, clockwise or counter-clockwise order). + +5b. **(Optional) Verify any corner you're unsure about.** If you're + not confident about a corner's exact (x, y) — typically when the + wall in the map image is fuzzy or you can't tell exactly where a + corner sits — call `frames_facing(x=, y=)`. + The tool projects that world point into every camera frame whose + cone could contain it and draws a red cross at the projection in + each. Look at the crosses: + - If the cross consistently lands on a visible wall corner, base + of a column, or actual wall edge in the recorded frames → the + corner is well-placed. + - If the cross lands away from any wall in the camera views → + move the corner to where the wall actually is. + Use this sparingly — one or two ambiguous corners per polygon, + not every corner. + +6. **Verify with `verify_room_partition`.** + ``` + verify_room_partition(rooms=[ + {"id": 1, "desc": "", "polygon": [[x, y], [x, y], [x, y], [x, y]]}, + {"id": 2, "desc": "", "polygon": [[x, y], [x, y], ...]}, + ... + ]) + ``` + The returned image overlays your rectangles on the occupancy map + semi-transparently and marks: + - GREEN dots = odom samples inside some room (✓) + - RED dots = odom samples OUTSIDE every room (you missed + somewhere the robot walked) + - ORANGE markers = the most SALIENT blobs of unpartitioned + free space the lidar saw. The marker size is + proportional to area; each is labelled in + m². Only meaningful blobs appear — tiny + single-cell stragglers along walls are + filtered out. + + Look at the image AND the per-room text. Four things to check: + 1. **No overlap warning.** If the text shows `⚠ overlap with →` + for any room, two of your polygons interior-overlap. Fix + it by shrinking one polygon so they share an edge instead + of crossing. + 2. **No red wash inside any polygon.** Red on the map means + the polygon covers UNKNOWN cells (cells lidar never saw — + space past walls). High `overclaim` percentage in the text + means the same thing. Shrink the polygon's corners inward + to follow the walls and remove the red. + 3. **Few RED dots.** Many red dots in a cluster mean part of + the robot's path isn't covered → extend the nearest + room's polygon outward (but stay inside the lidar-known + free space — don't trade off (2) for (3)). + 4. **No large orange marker inside the explored area + without a covering polygon.** A large orange marker far + from your polygons but in the lidar-mapped free space + means you missed a sub-room → extend an existing polygon, + OR (only if it's clearly separated by walls/doorway) add a + new room. + - Small orange markers at the edge of the explored area + (beyond an external wall) are lidar bleed-through — ignore. + + Iterate: adjust the rectangles, call `verify_room_partition` + again, repeat until you're happy. Cap iterations at ~3 — diminishing + returns after that. + +7. **Compute the final area from the verified polygons.** + `verify_room_partition` already returns per-polygon `area_m2` in + its text output. Copy those numbers into the answer; you don't + need a separate `calc` for the area when you used polygons. + + If you DO want to recompute or centroid-summarise in `calc`, use + the shoelace formula: + ```python + calc(''' + def poly_area(pts): + n = len(pts); s = 0.0 + for i in range(n): + x1, y1 = pts[i] + x2, y2 = pts[(i+1) % n] + s += x1*y2 - x2*y1 + return abs(s) / 2 + def poly_centroid(pts): + n = len(pts) + return (sum(p[0] for p in pts)/n, sum(p[1] for p in pts)/n) + + verified = [ + {"id": 1, "desc": "...", "polygon": [[x, y], ...]}, + {"id": 2, "desc": "...", "polygon": [[x, y], ...]}, + ] + for r in verified: + r["area_m2"] = poly_area(r["polygon"]) + r["centroid"] = poly_centroid(r["polygon"]) + verified.sort(key=lambda r: -r["area_m2"]) + verified + ''') + ``` + +7b. **Per-room visual verification.** + Before answering, sanity-check every room you defined by opening + at least 2 frames that you classified into it (pick frames whose + `(x, y)` is well inside the room's polygon — preferably one near + each end of the room). For each room: + + - Call `show_image(stream="color_image", ts=)`. + - Confirm out loud that what you see matches the room's `desc` + (e.g. desc says "retail / pantry / shelving area" → the frame + should actually show shelves/products, not a sofa lounge). + - If a frame contradicts the assigned room (e.g. you labelled it + "shelving area" but it shows the elevator corridor), the + classification is wrong. Either move that frame to the correct + room, merge two rooms that were really one, or split a room + that lumped two distinct spaces together. Then re-run + `verify_room_partition`. + + A room with only one classified frame is also a red flag — open + that frame and verify it's really a distinct space, not noise from + a doorway/transition. If unsure, merge it into a neighbour. + + This catches the common failure mode where pose-based bbox or + polygon tracing looked clean but the underlying frame-to-room + assignment was wrong. + +8. **Reply.** End your turn with a plain-text answer. Match the + answer shape to the question — the procedure above produces both + the count AND the per-room geometry, so use only what was asked: + + - **Count question** ("how many rooms", "did I change rooms"): + reply with just the integer (or "yes"/"no"). If the user asked + for "only the number", give only that. Do NOT dump the per-room + description list unless they asked for one. + - **Biggest-room question** ("where is the biggest room", "how + big is the biggest"): lead with that room and its area / + polygon. "Biggest" = largest verified-polygon area. + - **Sizing / bounds question** ("how big are the rooms", "what + are the dimensions of room X"): list every room with id, short + description, polygon corners, centroid (x̄, ȳ), area (m²) from + the verified polygon, and number of sample frames classified + into it. + + If the user added a format directive (e.g. "reply with only the + number, nothing else"), honour it strictly — the room polygons + and frame lists you computed are intermediate work, not the + final answer. + +## Discipline notes + +- The walked-coverage bbox from step 4 is a *lower bound*. The + verified rectangle in step 6 is what you actually report — extend + it on the map (step 5) to cover lidar-visible floor the robot + didn't step on but is clearly inside the room's walls. +- Don't extend a rectangle through walls or doorways into the next + room. The orange markers from `verify_room_partition` show + unpartitioned floor; some of those markers will be in adjacent + rooms or outside the building. Use your visual judgement on the + map to decide which markers should be absorbed by extending an + existing room vs which indicate genuinely separate rooms. +- **Prefer extending an existing room's wall to inventing a new + room.** A new room only makes sense if the unpartitioned area is + clearly separated from existing rooms by walls or a doorway. +- A "continuation" still adds the new frame's `(x, y)` to the + room's frame list — that's how the initial bbox grows. +- Don't conjure a number when you only have one sample in a room. + Say "extent unknown (only one sample)". +- Camera yaw / facing changes are not room changes. +- This procedure is geometry on top of the same pairwise visual + reasoning that `count_rooms` uses. If the visual classification is + wrong, the rectangles will be wrong too. diff --git a/dimos/memory2/experimental/memory2_agent/skills_registry.py b/dimos/memory2/experimental/memory2_agent/skills_registry.py new file mode 100644 index 0000000000..43f7bf6320 --- /dev/null +++ b/dimos/memory2/experimental/memory2_agent/skills_registry.py @@ -0,0 +1,69 @@ +# Copyright 2026 Dimensional Inc. +# SPDX-License-Identifier: Apache-2.0 + +"""Skill registry — load skill descriptions and bodies from ./skills/*.md. + +A "skill" is a step-by-step procedure for solving a particular kind of +problem.

Langgraph runs tool calls in parallel on a ThreadPoolExecutor, but every memory2 tool shares one sqlite3.Connection (check_same_thread=False) and one MontyRepl, so concurrent reads corrupt blob fetches ("No blob for stream='color_image', key=N" on rows that exist). Following the position_of_thing skill by hand also surfaced affordance gaps that explain inconsistent agent answers on short-baseline scenes. Changes (all in dimos/memory2/experimental/): - Per-build_tools threading.Lock wraps every tool body — serializes parallel langgraph tool calls so they don't race on the shared sqlite connection or REPL. - _fmt_pose includes yaw when the pose carries a quaternion, so the agent doesn't redo atan2(quat) on every bearing. - _fmt_obs drops id= — embedded vs raw stream ids collide; ts is already the canonical handle every other tool accepts. - frames_facing: new min_distance_m=1.0 filters cams that sit on the query point (their projected cross would land at the camera's own feet); picks displayed closest-first; annotated map moved to end so the agent reaches the first frame without scrolling past the map. - show_image: new mark_px / mark_label draws a yellow vertical guide bar — lets the agent verify which object instance it picked in frames with multiple instances of the target class. - position_of_thing.md: requires N>=3 rays with >=30 deg pairwise bearing separation before trusting rms (at N=2 the rms is zero by construction); points at the new yaw caption and mark_px workflow. Tests added (HK office): - acoustic_guitar_closest_robot_distance (~11 m, +/-2 m bound). - white_robots_count_4_hk replaces the 2-count case (true count is 4; 3 acceptable since one robot is barely visible in only two frames).
