Robotic hand leaderboard
A separate benchmark for assembling authored robotic-hand components. Amazing Hand and ORCA will be reported as distinct cases, not combined into one ranking.
Amazing Hand
In preparation · no ranked entries. Source CAD and an authored right-hand assembly have been inspected. Component identities, the parts list and reference placements still require reconciliation and acceptance.
ORCA
In preparation · no ranked entries. Repeated import and rigid-placement checks passed for five flagged source components. Their known geometry defects remain documented exceptions, not successful validity checks. Source-version and parts-list conflicts remain unresolved.
How results will be compared
Each published comparison must identify the hand, kit and scoring versions, model and effort, runtime, assistance conditions, and attempted and graded run counts. Repeated trials must report failures and variation, not just the best export.
Hand results are not comparable with M3-CRETE scores. Initial preparation concerns digital assembly placement; it does not establish grasping performance, strength, safe motion or physical buildability. Berkeley Lite is deferred.
Before scoring begins
Reconcile the source components and reference assembly; freeze separate worker kits and held-out references; validate hand-specific scoring; then qualify the runtime and automated execution. No evaluation campaign has started.
