Abstract

fetched live from OpenAlex

Robotic grasping systems that can clear clutter from a surface have many possible applications. One of these grasping systems could be implemented on a mobile robot that performs household chores. A grasping system could just as easily be implemented on a vehicular mobile base in order to perform grasping tasks in an outdoor environment. The Helping Hands Lab at Northeastern had implemented a grasping system that detected grasps using a convolutional neural network. Because this system was implemented on a Baxter Research Robot, kinematic inaccuracies contributed significantly to the grasp failures that the system encountered. In order to reduce this error, the grasping system was ported to the UR5 robotic arm. Experiments have shown that the kinematic error prevalent in the Baxter arm has not occurred once with the UR5. The arm was later mounted on a mobile Warthog base in order to show how portable the system is.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
