Unitree Go2 Specifications

Last updated: 2026-05-13

Last updated: May 2026

Four configurations exist: Go2 Air (entry), Go2 Pro (prosumer), Go2 EDU (research / SDK), and Go2-W (wheeled-leg hybrid, 2024). Air, Pro and EDU share the same chassis and 12-DoF leg structure but differ on compute, sensors and unlocked SDK access. Go2-W swaps in motorised wheel-feet on the lower leg segments. Where a row applies to all configurations only one figure is shown.
