Expert VerdictWinner: Go2
GO2 wins on value; B2 wins for industrial workloads
GO2 at $1,600-$2,800 is the best research quadruped value in history — ROS 2 SDK, global developer community, and lowest-cost entry to legged robotics. B2 wins for industrial applications: 40 kg payload vs GO2 8 kg, 5-hour battery vs 1.5 hours, IP67 weatherproofing, and 60 kg body weight for stability under heavy sensor loads. Research or development: GO2 is the obvious choice. Industrial inspection requiring 20+ kg sensor payloads on extended shifts: B2 is the right tool.
Go2 is better for
research, education, development, and any application where GO2 price and global ecosystem are decisive
B2 is better for
industrial inspection requiring 40 kg payload, 5-hour endurance, and IP67 protection in harsh environments
