The Wine Glass Test: Bimanual Dishwasher Loading Clears Zero-Breakage Threshold
Fourier GR-2 demonstrates tactile sensor feedback that handles thin crystal stemware without chips or fractures.
- Cleared 500 consecutive crystal wine glass dishwasher loading cycles with zero breakages.
- 1000Hz fingertip slip-vector sensing dynamically adjusts grip between heavy pots and thin stems.
- Bimanual coordination stabilizes racks with the left hand while slotting tableware with the right.
Loading a dishwasher is a deceptively delicate task. Grasping heavy porcelain casserole dishes requires substantial grip force, but immediately switching to ultralight crystal wine glasses requires sub-newton force calibration. In laboratory chore benchmarks, Fourier GR-2 has achieved zero breakages across five hundred consecutive cycles.
The robot uses tactile feedback sensors embedded across all five fingers, measuring slip vectors at 1000Hz. When grasping a wine glass by the stem, it applies just enough clamping force to prevent slipping, then pivots its wrist smoothly to position the glass upside down over the dishwasher rack prongs.
Bimanual coordination enables the robot to hold the dishwasher drawer open with its left arm while loading plates with its right, cutting cycle times down to standard human speeds while handling fragile cutlery and glasses with clinical precision.
Achieving zero breakage on crystal glassware overcomes a critical psychological barrier for homeowners entrusting expensive dinnerware to robots.
Organize plates by size on the counter before loading to allow your humanoid helper to maintain smooth, rapid placement cadence.
