Unitree G1 Humanoid Robot Summits Ecuador Volcano, Aims for Mount Everest

Unitree Robotics' humanoid robot G1 (modified version, named Pemba) successfully summited Ecuador's Chimborazo volcano (approx. 6,200m) on June 5, becoming the first humanoid robot to reach 20,000 feet. The project, led by French engineer Pablo Berlanga Boemare, aims to verify bipedal robots' autonomous walking in extreme environments, with the ultimate goal of climbing Mount Everest.

Summit Details and Modifications

• During the 16-hour ascent, G1 walked autonomously only on slopes under 30°; on steeper sections, expedition members carried it.
• The team made several modifications: custom ventilation/cooling system for high-altitude cold and electronics heat; structural reinforcement; new reinforcement learning strategies to improve slope traversal.
• At the summit, G1 wore a blue thermal jacket, black gloves, yellow leg covers, and raised one arm.

Project Background and Goals

• The project originated from environmental needs: replacing fixed camera networks for wildlife monitoring, anti-poaching, and environmental change tracking. The team believes bipedal robots can reach about 97% of the Earth's surface inaccessible to wheeled or tracked robots.
• The project proposes a "Triple Crown" plan: first stop Chimborazo (completed); second stop Mauna Kea, Hawaii (tallest mountain from ocean base); ultimate goal Mount Everest.

Everest Plan and Regulatory Challenges

• Plans to test the robot between Everest Base Camp and Camp 4 (approx. 8,000m), collecting data on battery life, mobility, joint stress, and environmental tolerance. Partner is Nepal's Fourteen Peaks Expedition company.
• Nepal currently has no legal framework for "robot climbing Everest"; officials require rules first. Consequently, the Everest timeline has been delayed, tentatively set for October 2026, possibly postponed to April 2027.

Lead and Future Outlook

• Project initiator Pablo Berlanga Boemare is a French engineer who dropped out of engineering school, worked in environmental conservation at WWF, and later founded Geologic Dome. His field experience inspired the Pemba project.
• Unitree G1 previously demonstrated cold resistance at -47.4°C in Altay, Xinjiang, showing platform survivability in extreme cold.
• Although G1 still needs carrying on steep slopes, the project demonstrates humanoid robots' potential for extreme terrain applications, such as garbage cleanup, glacier monitoring, search and rescue, and environmental surveying.
