Start with a failure you can observe. A slipping object, missing contact location, drifting signal, and unusable training data need different measurements. These workflows help define what to test next.
Use case
Problem: Successful initial contact does not establish that the grasp will survive movement or disturbance.
Impact: Separate slip detection from the recovery action and the final object-retention outcome.
Suggested route: Start with slip cues, then compare sensor latency, false alarms, and closed-loop recovery evidence.
Note: Record disturbances, contact geometry, and failed recoveries as well as successful trials.
Use case
Problem: A fingertip sensor covers only a small part of the surfaces that may contact the environment.
Impact: Map likely contact regions before selecting distributed sensing and connecting readings to robot coordinates.
Suggested route: Review whole-hand, arm, and body coverage together with wiring, compliant mounting, and data routing.
Note: Contact awareness is an input to a control system; it does not establish safety certification.
Use case
Problem: A new contact surface, lighting condition, or mounting arrangement can invalidate an earlier baseline.
Impact: Keep raw measurements, reconstructed geometry, and force estimates separate when diagnosing drift.
Suggested route: Define the measurement target, record a baseline, and validate calibration on held-out contacts.
Note: An optical image is not automatically a calibrated force map.
Use case
Problem: A paper describing tactile recordings does not guarantee downloadable data or a reusable license.
Impact: Check access, modality, embodiment, tasks, synchronization, and splits before choosing a dataset.
Suggested route: Use the tactile dataset directory, then inspect the primary files and evaluation protocol.
Note: Keep adjacent frames from one trajectory out of both training and test splits.
Write down the object, contact surface, operating conditions, measured signal, and desired outcome. Then compare a baseline with the tactile system using the same task and failure criteria.
