⚠️ A working draft under continuous verification. Link curl check: 16 are 200; two more are non-dead-links per project convention and still cited with annotation — Nihon Binary (curl 000, cert altname mismatch / suspected geo, WebFetch-readable) and RobotShop (curl 403, needs browser UA). Two caveats first: (1) Japan channels are all quote-based, with no public JPY price — JPY figures here are US-dealer-listing conversions (1 USD≈¥157, 2026 scale), not Japan actuals; you must actually send an RFQ. (2) Specs per www.unitree.com/go2/, prices per shop/dealers.

🌐 What this answers

Picking up GO2 selection's conclusion — starting with GO2 means EDU only (only EDU opens full secondary development / low-level control; Air/Pro are locked and can't plug into an AMR). This article does one thing: how to actually buy EDU in Japan — channels, a price anchor, and an RFQ checklist you must confirm in writing.

Integration / self-built middleware → Self-built middleware architecture; haulage selection → Haulage selection.

🔑 1. The key insight: in Japan, EDU is the "R&D model"

In Japan, the secondary-development-open version is not called "EDU" — it's the "R&D model (R&Dモデル)", Unitree's Japan-market name for the tier. Look for the word "R&D" when buying, or you'll be steered to a consumer version.

  • The official Japan agent TechShare states clearly: Air/Pro don't allow software dev; only R&D opens secondary development, R&D includes the "Unitree Legged SDK2 dev environment" + high-level/low-level API + ROS + dock I/O3.
  • Dealer Tohasen further splits R&D (40 TOPS) vs R&D Plus (100 TOPS Jetson Orin), with EDU navigation listed separately8.
  • "Only EDU/R&D works out-of-the-box" has community corroboration: CycloneDDS out-of-the-box is EDU/R&D only, Air/Pro need a firmware mod15; "only EDU/EDU+ supports programming"16.

🏪 2. Japan procurement channels

  • TechShare contact: Sales Unitree team / Tel 03-5683-7293 / unitree@techshare.co.jp3. TechShare started R&D pre-orders in Japan from 2023-09 (Air early-bird was once ¥498,000 ex-tax — that's Air, not EDU, scale reference only)4.
  • Japan deployability is corroborated by a third-party hands-on (Classmethod DevelopersIO received a Go2 unit for review)10.
  • ⚠️ Unitree's site lists no official Japan dealers; TechShare's "agent" status is from its own page + press release — cross-confirm Japan agency by email to the official (sales_global@unitree.cc).

📋 3. RFQ checklist (send to suppliers as-is)

When quoting from TechShare / Tohasen / Unitree official, confirm the following in writing, especially Group A (dev access) — the life-or-death line for "did we buy the right version that can plug into an AMR."

A. EDU/R&D dev access (most critical, confirm in writing)

  1. CycloneDDS out-of-the-box (runs on the shipped firmware, no self-mod)15.
  2. unitree_sdk2 / unitree_ros2 fully open, not gimped (confirm LowCmd: torque/position/velocity + kp/kd)14.
  3. Low-level rt/lowcmd torque/joint control scope — confirm EDU's native DDS path supports /lowcmd; note Sport Mode must be released first (MotionSwitcher / disable_sports_mode) before low-level commands (an all-model interlock, not an EDU limit, but put it in the delivery note)16.
  4. Firmware policy: shipped firmware version, whether affected by "Motion Service Interface V2.0" (2026-02 high-level API rework deprecating the old Sport Mode service on new firmware), and no blind downgrades (old downgrades can break Secure Boot/boot).
  5. Use native CycloneDDS, not WebRTC — rt/lowcmd is not fully supported over the WebRTC path.

B. Version / SKU

  1. Compute tier: 40 TOPS (Orin Nano, R&D/EDU) vs 100 TOPS (Orin NX, R&D Plus/EDU Plus).
  2. Battery: the 15000mAh long-life version? (stock may be 8000mAh).
  3. LIDAR: stock 4D / Mid-360 / Hesai XT16 (only EDU Plus has 3D LIDAR + nav-algo options).
  4. D1 arm option included? unit price, interface power (16–60V).
  5. RealSense D435i depth cam, controller, fast charge included?

C. Plant-environment fit (not on the official site, must ask)

  1. IP rating + operating temp/humidity — www.unitree.com/go2/ lists no IP rating; oily/humid plant environments require the supplier to state whole-unit and joint IP rating + operating envelope in writing.

D. Commercial

  1. JPY price incl. tax (body + options itemized).
  2. Lead time / stock (Tohasen says 1–3 biz days; confirm for EDU specifically).
  3. Warranty (Tohasen R&D = 6 months; Airpuria/official = 1 year — Japan channel must confirm).
  4. Tech support / training (SDK onboarding, support scope for integrating ROS2 into an AMR).
  5. Spares (battery/motor/dock) supply and price.
  6. PoC trial/lease or academic/research discount available?

💰 4. Price anchor (official quote-based vs third-party)

Rate reference 1 USD≈¥157 (2026 scale, per quote date).

Source Type SKU Listed JPY (ref) Note
shop.unitree.com Official GO2 EDU quote-based (not public) — sales_global@unitree.cc2
Airpuria (US · non-official) third-party GO2 EDU (40TOPS+4D LIDAR+15000mAh+D435i) $13,900 ≈¥2.18M 1-yr warranty11
Airpuria (US · non-official) third-party GO2 EDU Plus (100TOPS Orin NX) $16,900 ≈¥2.65M Mid-360/Hesai option12
RobotShop (US · non-official) third-party GO2 EDU no price (curl 403) — needs browser UA, non-dead
  • Official EDU is quote-only, no public listing; Airpuria's $13,900–16,900 / ¥2.18M–2.65M is the only quantifiable anchor (non-official), good as a negotiation anchor with TechShare13.
  • ⚠️ Search snippets once showed inconsistent EDU $14,500 / EDU Plus $22,500 — trust the product pages $13,900 / $16,900; snippet values are dubious.

🎯 5. Honest recommendation for the boss

  1. Look for "R&D model" — Japan doesn't call it EDU. Prefer the official Japan agent TechShare (CN/JP comms + SDK dev env + local warranty), the easiest legit entry; also get quotes from Tohasen (in stock, ships 1–3 days, comparable price) and Unitree official (sales_global@unitree.cc) for cross-comparison.
  2. Put Group-A dev access in the RFQ as written terms — the life-or-death line: CycloneDDS out-of-the-box + unitree_sdk2/ros2 full + /lowcmd usable. Buying wrong (Air/Pro or gimped firmware) = can't plug into an AMR, all wasted (see GO2 selection).
  3. Budget anchor ≈ ¥2.18M–2.65M (EDU/EDU Plus US conversion, non-official); Japan actuals come from the quote and usually run higher with tax + local support — budget at this scale + options (LIDAR/arm) on top.
  4. Two plant-environment items the site lacks, must obtain: IP rating, and real endurance (stock 8000mAh vs long-life 15000mAh — schedule charging to the real cadence).

⚠️ For you to verify / to add

  1. Want me to turn Section 3's checklist into ready-to-send Japanese RFQ emails (one each for TechShare/Tohasen/Unitree official), embedded into the client proposal (docx/ppt)?
  2. Lock the compute tier/options: 40 vs 100 TOPS for the PoC, D1 arm or not, which LIDAR — once set I'll converge the RFQ to one definite SKU.
  3. Actual JPY price: after TechShare/Tohasen return formal quotes, I'll update the budget table to actuals.
  4. Warranty terms: lock the Tohasen-6-months vs official-1-year gap in the contract.
