It walks at about 6 km/h, carries about 3 kg per hand and runs for roughly three hours on hot-swappable batteries. Fourier positions it for homes, public spaces and assisted-living settings.",

GR-2 (September 2024): 1.75 m, 63 kg, 53 DOF, 3 kg single-arm load per Wikipedia; no current GR-2 sales page was fetched. Price on request. Max speed converted from the stated 6.1 km/h.
