# Robot Manipulation Deployment Checks

## Summary
Robot manipulation teams can make three concrete changes with current evidence: score demonstration labels by physical interaction signals, add fixed-latency decoding tests before deploying autoregressive VLA policies, and test tactile policies across sensor types before standardizing contact hardware.

## Interaction-based reliability scoring for robot demonstration labels
Robotics data teams should add a reliability gate to auto-labeling pipelines for manipulation demonstrations. SPARC shows a practical pattern: identify the object being manipulated through gripper phase, language parsing, object masks, tracking, 3D lifting, object motion, gripper proximity, and robot-body overlap. The output is a label plus a reliability score, so data teams can choose a precision target and keep the usable subset for training.

This directly addresses a common failure in cluttered robot videos: a detector can assign high confidence to the wrong object. A useful first implementation would run the current detector-and-tracker labels beside an interaction-based scorer on a few thousand demonstrations, then hand-audit only samples near the acceptance threshold. SPARC reports 80.2% interacted-object localization accuracy on IA-Bench, compared with 58.1% for a detector-confidence baseline, and keeps 77.6% coverage at a 90% precision operating point.

## Fixed-latency decoding tests for autoregressive VLA policies
Teams deploying autoregressive VLA policies should treat latency as a testable policy constraint before robot trials. The real-time execution paper gives a concrete recipe: adjust action chunk tokenization, condition on the previous action chunk, decode only the needed part of the next chunk, and use constrained decoding so every generated token sequence can finish within the controller’s latency budget.

The deployment check is straightforward. Run the policy against the robot command interval, measure stalls and invalid action chunks, and compare task success with synchronous inference and an existing real-time control baseline. The paper reports 95.7% average task success for pi0-REALFAST on LIBERO, compared with 89.4% for pi0 plus real-time control and 94.7% for pi0.5 plus real-time control. It also reports small added decoding costs in the tested settings, including examples around 4 to 13 ms.

## Cross-sensor tactile transfer tests for contact-rich manipulation
Robot teams adding tactile sensing should test policy transfer across sensor hardware before committing to one tactile stack. FTP-1 shows a concrete support layer for this: map image, array, and state tactile inputs into a shared morphology-aware token space, model those tactile tokens with a shared Transformer expert, and fuse them with a VLA-style policy.

A practical adoption test would pick two contact-rich tasks such as sliding, grasp stabilization, or insertion, train with one tactile sensor, then run the same policy branch on a held-out sensor setup. This catches the hardware lock-in problem early. FTP-1 pretrains on about 3,000 hours of tactile data from 26 sources and 21 tactile sensors, then reports 46.6% average success on unseen sensor setups, compared with 15.0% for its FTP-pi0.5 baseline.
