Embodied representation: the environment is more than input

Research question

Moving an object onto a table requires more than recognizing its name. Reachable areas, contact relationships and motion constraints all matter. Without these conditions, even correct recognition can produce an impossible plan.

Research method

Represent observations, goals, spatial relationships and preconditions around task-relevant states. Preserve the source and time of every update. Keep inference separate from observation so unconfirmed judgments do not become the basis for subsequent action.

Validation approach

  1. Build comparison scenarios with position changes, occlusion and ambiguous instructions.
  2. Compare object lists and relational representations in task reasoning.
  3. Record whether errors originate in observation, state updates or missing constraints.

RESEARCH PROTOCOL

Representation experiments: beyond objects

Express the same task as an object list and a relationship graph. The list records categories and coordinates; the graph also captures support, obstruction, contact and reachability. Keep goals and environments identical and compare omitted constraints in the resulting plans.

Experimental design & observations

StageWhat to recordWhat to check
Tabletop manipulationObject pose, grasp region, supporting surfaceIs the goal reachable, and are all action preconditions present?
Occlusion recoveryLast observation time, occlusion source, confidence rangeDoes the system mistake a past position for the current state?
Goal changeNew goal, executed actions, remaining spaceCan the system explain which plans are no longer valid?

Making results comparable

Fix the initial map, endpoints and input version, then change one environmental condition at a time. Record the baseline before introducing obstacles or conflicting inputs. Include successful paths and failure cases. Compare strategies using path length, explored cells and execution traces.

Reproducibility checklist

  • Input and map snapshots: record scene versions, task conditions and random seeds.
  • Strategy configuration: record algorithms, constraints, timeouts and human intervention points.
  • Execution traces: retain state changes, action sequences, failure causes and recovery steps.
  • Comparison notes: document variable changes, observations and follow-up validation.
