grasping-direct-ik

Direct-IK grasp: rotate the gripper to grasp orientation at a safe height above the target, then descend straight down, then close. No trajectory planner — works on platforms where CuRobo is not deployed, or in uncluttered scenes where planning is overkill.

Nothing here is written for one hand. The grasp rotation is composed by the connector's robot.grasp_frame from the hand's measured approach and closing axes, the fingertip floor and the hover clearance come from robot.describe_gripper / robot.describe_workspace, so the same subgraph grasps the same way on a hand that closes along tool-local x and on one that closes along tool-local y.

When to use

The curobo tool bundle is not deployed (no collision-aware planner available).
The scene is uncluttered enough that a straight-line approach is safe.

When NOT to use

Cluttered scenes where the arm must thread between obstacles. Prefer grasping-with-planner if available.

Recommended subgraph state flow

The subgraph state machine the agent generates should look like (7 states):

open → compute_grasp → refine_grasp → compute_align → rotate_align → descend → close → grasped

(grasped is the success-marker noop from sg.add_exit("grasped"), with an edge to END.)

State details:

open — type: tool, tool: "robot.open_gripper", inputs: { settle_steps: 40 }.
compute_grasp — type: tool, tool: "geometry.top_down_grasp_candidates", inputs: { obb: Ref("in.target_obb") }.
refine_grasp — type: script, file scripts/<sg>/refine_top_down_grasp.py (from this bundle's canonical_scripts). Inputs: grasp_pose = Ref("compute_grasp.candidates.poses.0"), target_obb = Ref("in.target_obb"). Returns grasp_pose: the candidate with its rotation rebuilt so this hand's closing axis lies across the OBB's short horizontal axis (robot.describe_gripper + robot.grasp_frame(approach=-z, close_heading_deg)), and its Z raised to the fingertip floor (support_z + finger.reach_m + finger.clearance_m) when the hand states its finger envelope. Keep this state: the candidate fan is world-aligned and a thin object's centred grasp jams the jaws on the table without the floor.
compute_align — type: script, file scripts/<sg>/compute_align_pose.py. Inputs: grasp_pose = Ref("refine_grasp.grasp_pose"), target_obb = Ref("in.target_obb"), optionally clearance (a literal in metres). Returns align_pose at the grasp XY and rotation, with z = max(obb_top, grasp_z) + clearance. Omit clearance (or pass 0) and the script asks robot.describe_workspace for align_clearance_m — the hand's own envelope above the fingertips. Pin it (e.g. 0.12) when the held object is what needs the room, such as a long tool that will hang below the fingertips on the way up.
rotate_align — type: tool, tool: "robot.go_to_pose", inputs: { pose: Ref("compute_align.align_pose") }.
descend — type: tool, tool: "robot.go_to_pose", inputs: { pose: Ref("refine_grasp.grasp_pose") } — the same pose compute_align was given, so hover and grasp share one rotation.
close — type: tool, tool: "robot.close_gripper", inputs: { settle_steps: 60 }. Edge directly from close to the grasped success marker; the subgraph's on_error: "failed" catches any raise from earlier steps. Whether the gripper actually closed on the object is checked by the target_held postcondition checkpoint (see ## Checkpoints), NOT by a re-check-and-raise node (none such exists).
```
"edges": [ ..., ["close", "grasped"], ["grasped", "END"] ],
"conditional_edges": {},
"exit": { "router_field": null, "success_values": ["grasped"] },
"on_error": "failed"
```
The lift onto a safe carry height is handled by the next transporting-objects subgraph (its waypoint_move script lifts before lateral motion); do NOT add a lift step here.

scripts/<sg>/plan_to_pose.py is the optional planned variant of a single leg: it calls curobo.plan_to_pose from the observation's joint state to a target pose and returns the trajectory (raising PlanningFailed when the planner refuses) for a platform that deploys CuRobo as a fast single-pose IK fallback without the goalset grasp planner.

Hard rules

Use geometry.top_down_grasp_candidates (returns candidates: {poses: list[Se3Pose]}), not geometry.top_down_grasp_from_obb (single bare pose). The refine and align-pose constructions assume compute_grasp.candidates.poses.0 exists.
The align_pose descends straight down with the gripper pre-rotated. Do NOT skip the compute_align + rotate_align states — a direct robot.go_to_pose to the grasp pose blends rotation and descent and twists the gripper against the object.
descend uses the pose compute_align was given (refine_grasp.grasp_pose). Never descend to the raw candidate after hovering at the refined rotation.

Required end states

End state	Meaning
`grasped`	Gripper has closed on the object after the descend. Route to next subgraph (typically `transporting-objects`).
`failed`	Any grasp-attempt failure: planning failure or trajectory execution error (a raise to `on_error`). Coordinator routes to abort. Lives only in `on_error` — never declare a `failed` node.

scripts/refine_top_down_grasp.py — the close-axis rotation and fingertip floor, read off the live hand.

scripts/plan_to_pose.py — the optional CuRobo single-pose leg.

# grasping-direct-ik

Direct-IK grasp: rotate the gripper to grasp orientation at a safe height
above the target, then descend straight down, then close. No trajectory
planner — works on platforms where CuRobo is not deployed, or in
uncluttered scenes where planning is overkill.

Nothing here is written for one hand. The grasp rotation is composed by the
connector's `robot.grasp_frame` from the hand's measured approach and closing
axes, the fingertip floor and the hover clearance come from
`robot.describe_gripper` / `robot.describe_workspace`, so the same subgraph
grasps the same way on a hand that closes along tool-local x and on one that
closes along tool-local y.

## When to use

- The `curobo` tool bundle is not deployed (no collision-aware planner
  available).
- The scene is uncluttered enough that a straight-line approach is safe.

## When NOT to use

- Cluttered scenes where the arm must thread between obstacles. Prefer
  `grasping-with-planner` if available.

## Recommended subgraph state flow

The subgraph state machine the agent generates should look like (7 states):

```text
open → compute_grasp → refine_grasp → compute_align → rotate_align → descend → close → grasped
```

(`grasped` is the success-marker `noop` from `sg.add_exit("grasped")`,
with an edge to `END`.)

State details:

1. **`open`** — `type: tool`, `tool: "robot.open_gripper"`, `inputs: { settle_steps: 40 }`.
2. **`compute_grasp`** — `type: tool`, `tool: "geometry.top_down_grasp_candidates"`,
   `inputs: { obb: Ref("in.target_obb") }`.
3. **`refine_grasp`** — `type: script`, file
   `scripts/<sg>/refine_top_down_grasp.py` (from this bundle's
   `canonical_scripts`). Inputs:
   `grasp_pose = Ref("compute_grasp.candidates.poses.0")`,
   `target_obb = Ref("in.target_obb")`. Returns `grasp_pose`: the candidate
   with its rotation rebuilt so this hand's closing axis lies across the
   OBB's short horizontal axis (`robot.describe_gripper` +
   `robot.grasp_frame(approach=-z, close_heading_deg)`), and its Z raised to
   the fingertip floor (`support_z + finger.reach_m + finger.clearance_m`)
   when the hand states its finger envelope. Keep this state: the candidate
   fan is world-aligned and a thin object's centred grasp jams the jaws on
   the table without the floor.
4. **`compute_align`** — `type: script`, file
   `scripts/<sg>/compute_align_pose.py`. Inputs:
   `grasp_pose = Ref("refine_grasp.grasp_pose")`,
   `target_obb = Ref("in.target_obb")`, optionally `clearance` (a literal in
   metres). Returns `align_pose` at the grasp XY and rotation, with
   `z = max(obb_top, grasp_z) + clearance`. Omit `clearance` (or pass `0`)
   and the script asks `robot.describe_workspace` for `align_clearance_m` —
   the hand's own envelope above the fingertips. Pin it (e.g. `0.12`) when
   the *held* object is what needs the room, such as a long tool that will
   hang below the fingertips on the way up.
5. **`rotate_align`** — `type: tool`, `tool: "robot.go_to_pose"`,
   `inputs: { pose: Ref("compute_align.align_pose") }`.
6. **`descend`** — `type: tool`, `tool: "robot.go_to_pose"`,
   `inputs: { pose: Ref("refine_grasp.grasp_pose") }` — the same pose
   `compute_align` was given, so hover and grasp share one rotation.
7. **`close`** — `type: tool`, `tool: "robot.close_gripper"`, `inputs: { settle_steps: 60 }`.
   Edge directly from `close` to the `grasped` success marker; the
   subgraph's `on_error: "failed"` catches any raise from earlier steps.
   Whether the gripper actually closed on the object is checked by the
   `target_held` postcondition checkpoint (see `## Checkpoints`), NOT by
   a re-check-and-raise node (none such exists).

   ```json
   "edges": [ ..., ["close", "grasped"], ["grasped", "END"] ],
   "conditional_edges": {},
   "exit": { "router_field": null, "success_values": ["grasped"] },
   "on_error": "failed"
   ```

   The lift onto a safe carry height is handled by the next
   `transporting-objects` subgraph (its `waypoint_move` script lifts before
   lateral motion); do NOT add a lift step here.

`scripts/<sg>/plan_to_pose.py` is the optional planned variant of a single
leg: it calls `curobo.plan_to_pose` from the observation's joint state to a
target pose and returns the `trajectory` (raising `PlanningFailed` when the
planner refuses) for a platform that deploys CuRobo as a fast single-pose IK
fallback without the goalset grasp planner.

## Hard rules

1. Use `geometry.top_down_grasp_candidates` (returns
   `candidates: {poses: list[Se3Pose]}`), not
   `geometry.top_down_grasp_from_obb` (single bare pose). The refine and
   align-pose constructions assume `compute_grasp.candidates.poses.0` exists.
2. The `align_pose` descends straight down with the gripper pre-rotated.
   Do NOT skip the `compute_align` + `rotate_align` states — a direct
   `robot.go_to_pose` to the grasp pose blends rotation and descent and
   twists the gripper against the object.
3. `descend` uses the pose `compute_align` was given (`refine_grasp.grasp_pose`).
   Never descend to the raw candidate after hovering at the refined rotation.

## Required end states

| End state | Meaning |
|---|---|
| `grasped` | Gripper has closed on the object after the descend. Route to next subgraph (typically `transporting-objects`). |
| `failed` | Any grasp-attempt failure: planning failure or trajectory execution error (a raise to `on_error`). Coordinator routes to abort. Lives only in `on_error` — never declare a `failed` node. |
