Fourier GR-1 vs Fourier GR-2
Verdict
A generational transition at Fourier. The GR-1 (2023, 165 cm, 55 kg) drew attention with a high declared 50 kg payload and 40 degrees of freedom; the GR-2 (2024, 175 cm, 63 kg) raised the count to 53 and improved the hands, though its payload is reported differently. Facts vs hype: the GR-1 scores on declared raw payload, the GR-2 offers more dexterity and a more mature build.
