Key facts
- Official product page (fetched 2026-10-17): 600 x 690 x 1,400 mm, travel speed 1.5 m/s, 3 kg per arm, 48 VDC supply.
- DoF: wheels 2 (A) or 4 (M) + leg 6 + arms 7x2 + head 2 = 24 (A) / 26 (M); the page's intro text also says 24 for the system. The page's own 20 is the whole-body-manipulation DoF (leg 6 + arms 14), not the total.
- Total weight 131 kg (A: upper body 38 + lower body 42 + base 51) or 170 kg (M: base 90 kg).
- Battery 50 V: 25 Ah / 1,250 Wh (A) or 50 Ah / 2,500 Wh (M); runtime not published.
- The page lists a '40 C' operating-temperature cell without a min/max label, so it is not entered.
- Teleoperation leader arms (14 DoF, 3.86 kg; stand version 18.5 kg) are sold as accessories; SDK on GitHub (RainbowRobotics/rby1-sdk).
- Rainbow's launch coverage quoted 2.5 m/s and '22 axes excluding wheels'; the current product page says 1.5 m/s, which is used here. Launch date not verified.
