Overview
- Eastworlds Labs and Geologic Dome say their modified Unitree G1 humanoid, named Pemba, reached the summit of Mount Chimborazo on June 5, 2026 and was carried over technical sections while walking autonomously on gentler slopes.
- The robot weighs about 35 kg, was repeatedly disassembled and reassembled between camps for transport, and required human assistance on steep or technical parts of the 16-hour ascent.
- Organizers outfitted the G1 with cold-weather jackets, composite feet and an autonomy stack trained in NVIDIA Isaac Sim that the team cites as having an 85% sim-to-real transfer, a vendor-supplied metric not independently verified.
- Eastworlds Labs and Geologic Dome say the Chimborazo test will feed into a planned fall Everest campaign that includes media production and a promised donation of the robot to local Sherpa partners.
- Reporters note the conservation focus on using humanoids for remote monitoring, the project's commercial and PR framing, and minor reporting inconsistencies such as differing summit elevation figures in coverage.
