robotindex Unitree Go2
Unitree's mainstream quadruped robot dog, shipping across four tiers (Air / Pro / X / EDU) with chin-mounted 4D LiDAR, autonomous obstacle avoidance, and an app-based control ecosystem. The EDU tier adds full SDK access and an optional Jetson Orin module for custom development.

Reference Price
From $1,600 (Go2 Air); Go2 Pro is $2,800, Go2 X is $4,500, and Go2 EDU is contact-for-price since Unitree does not list it publicly. Unitree cut prices across the Go2 line during 2026; at $1,600, Go2 Air is now the cheapest robot Unitree sells. Specs and features vary meaningfully by tier, so treat any single quoted price or spec as tier-specific — see the comparison below.
| Tier | Price | Notes |
|---|---|---|
| Go2 Air | $1,600 | Base config — no 4G, no follow-me mode, 6-month warranty |
| Go2 Pro | $2,800 | Adds 4G module, ISS 2.0 follow-me mode, voice function, 12-month warranty |
| Go2 X | $4,500 | Limited secondary development support |
| Go2 EDU | Contact sales | Full developer SDK, force-sensor feet, optional Jetson Orin (40–100 TOPS) |
Sensors & Hardware
All standard tiers ship with a chin-mounted 4D LiDAR (360°×90–96° coverage, 0.05m minimum range) for real-time obstacle avoidance and 3D mapping, paired with an HD wide-angle camera system and an onboard mic for offline voice commands. Compute is an 8-core CPU on Pro/X/EDU versus basic onboard computing on Air; EDU supports an external NVIDIA Jetson Orin module for custom AI.
Insights
Go2's four tiers differ far more than price: only the EDU tier includes a full developer SDK, force-sensor feet, and support for an external NVIDIA Jetson Orin module, while Air, Pro, and X ship as closed, non-developer configurations. Go2 EDU also carries no public price — Unitree quotes it only through direct sales, unlike the other tiers' published $1,600–$4,500 range.
