Planar frictional micro-conveyors with two degrees of freedom
Bibliographic record
Abstract
The design, fabrication and operation of planar frictional micro-conveyors with two degrees of freedom (2-DOF) were investigated. The frictional micro-conveyors consisted of two parts: a driving unit and a mobile plate. The driving unit was comprised of thermal actuators which were attached to inverted feet. The plate was in constant frictional contact with the feet surfaces and by properly sequencing the motion of the feet, the plate moved with stepwise advances. Two different 2-DOF designs were constructed: an X –θ conveyor capable of linear and rotational yaw motions and an X – Y conveyor capable of planar translation. Both types of micro-conveyors were fabricated using 10 µm thick silicon-on-insulator technology. The X –θ driving unit's size was 580 × 960 µm 2 and it moved a 700 × 380 µm 2 plate. The X – Y driving unit's size was 720 × 720 µm 2 and it moved a 530 × 530 µm 2 plate. The X –θ conveyor was capable of moving the plate at a linear speed of up to 33 µm s −1 and a rotational speed of up to 7° s −1 . The X – Y conveyor was capable of translating the plate at a speed of 20 µm s −1 along either axis. The conveyors were able to transport loads in excess of 850 µg.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
