Abstract
Playbot is a long-term, large-scale research project, whose goal is to provide a vision-based computer controlled wheelchair that enables children and adults with mobility impairments to become more independent. Within this context, we show how Playbot can actively search an indoor environment to localize a door, approach the door, use a mounted robotic arm to open the door, and go through the door, using exclusively vision-based sensors and without using a map of the environment. We demonstrate the effectiveness of active vision for localizing objects that are too large to fall within a single camerapsilas field of view and show that well-calibrated vision-based sensors are sufficient to safely pass through a door frame that is narrow enough to tolerate a wheelchair localization error of at most a few centimetres. We provide experimental results demonstrating near perfect performance in an indoor environment.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
