Figure unveils fireproof humanoid robot battery for next-gen safety

Figure, a California-based robotics company, has unveiled its F03 battery, a fireproof, high-capacity energy solution designed specifically for its humanoid robots. The 2.3 kWh battery delivers up to five hours of peak performance runtime and represents a 94% increase in energy density over the original F01 model, while also reducing costs by 78% compared to the previous F02 version. Unlike earlier designs that relied on bulky external packs, the F03 is fully integrated into the robot’s torso, using structural materials such as stamped steel and die-cast aluminum to serve as a load-bearing component. This integration enhances mechanical durability, saves space and weight, and includes an active cooling system enabling safe, fast charging at 2 kW. Safety is a major focus of the F03 battery, which is the first in the humanoid robotics sector to pursue certification under both UN38.3 and UL2271 safety standards. The battery incorporates multiple protective layers, including thermally insulating
