Humanoid robot Qestr exits Antarctic race after 3 km

Humanoid robot Qestr withdrew from the Antarctic Ice Ultra on November 8, 2026, after just three kilometers. Competing alongside 25 humans in minus 24°C near Ultima Camp, Qestr's lithium-ion battery failed despite a custom thermal jacket. The early exit highlights critical gaps in battery and thermal technology needed for robots to operate in extreme environments.
