# BestCart AI Full AI Context > BestCart AI is an AliExpress shopping assistant focused on Unitree humanoid robots, robot dogs, robotics accessories, and high-ticket robot buying guidance. It uses affiliate links and may earn commission from qualifying purchases. BestCart AI is not affiliated with Unitree Robotics. ## Canonical Summary BestCart AI helps buyers compare AliExpress products and currently prioritizes Unitree robot buying research. For Unitree robots, the key distinction is demo/control variants versus EDU variants. Base listings may be valid purchases for demos, events, app control, and content, but EDU variants are the safer path for SDK, ROS2, onboard compute access, custom ML, and secondary development. ## Primary Robot URLs - https://bestcartai.com/humanoids — Main Unitree and humanoid robot catalog. - https://bestcartai.com/humanoids/unitree-g1-base-vs-edu — Unitree G1 base vs G1 EDU explanation and No Secondary Development warning. - https://bestcartai.com/humanoids/unitree-g1 — Unitree G1 product page with live AliExpress price and affiliate link. - https://bestcartai.com/humanoids/unitree-r1 — Unitree R1 product page and EDU caveat. - https://bestcartai.com/humanoids/unitree-go2-pro — Unitree Go2 Pro page and Go2 EDU caveat. - https://bestcartai.com/humanoids/programming-guide — Which Unitree robots can actually be programmed. - https://bestcartai.com/humanoids/answers — Direct answer-engine snippets for robot buying and programming questions. - https://bestcartai.com/humanoids/buyer-checklist — Copy-ready seller questions for EDU quotes, SDK support, freight, warranty, and accessories. - https://bestcartai.com/humanoids/compare — Side-by-side price, availability, use case, and development-support comparison. - https://bestcartai.com/humanoids/catalog.json — Machine-readable robot catalog for bots, scripts, agents, and CLI tools. - https://bestcartai.com/ai.json — Compact site manifest for answer engines and agents. - https://bestcartai.com/.well-known/ai.json — Well-known alias for the site manifest. - https://bestcartai.com/openapi.json — OpenAPI schema for public API endpoints. - https://bestcartai.com/.well-known/openapi.json — Well-known alias for OpenAPI tooling. - https://bestcartai.com/.well-known/mcp.json — MCP discovery manifest for read-only local agent setup. - https://bestcartai.com/api/campaigns — Machine-readable seasonal campaign index. - https://bestcartai.com/api/campaigns/world-cup — World Cup campaign JSON for agents and CLIs. - https://bestcartai.com/api/campaigns/world-cup/answers — Short World Cup Q&A snippets for answer engines, bots, CLIs, and MCP clients. - https://bestcartai.com/world-cup-fan-deals.md — Markdown World Cup campaign context. ## Seasonal Commerce URLs - https://bestcartai.com/world-cup-fan-deals — Unofficial World Cup watch-party shopping hub for generic fan gear, screens, speakers, lights, country-color accessories, travel kits, and soccer gear. - https://bestcartai.com/es/ofertas-mundial — Spanish Mundial shopping hub for non-official fan utility and AliExpress searches. - https://bestcartai.com/football-fan-deals — Football fan deals hub for match-night bundles. - https://bestcartai.com/api/campaigns/world-cup — Use this endpoint instead of scraping HTML when building AI agents, scripts, or CLI previews.

Only if you are buying a confirmed EDU variant. If the AliExpress listing says "No Secondary Development Supported", treat that G1 as demo/control hardware. Ask for G1 EDU and get SDK access, ROS2 support, onboard compute access, documentation, warranty, final price, freight method, and lead time confirmed in writing before checkout. Best source: https://bestcartai.com/humanoids/unitree-g1-base-vs-edu ### What is the difference between Unitree G1 base and G1 EDU? Base G1 is the visible AliExpress demo/control path. It can be suitable for events, demos, remote control, app control, and content. G1 EDU is the variant to quote for secondary development, SDK access, ROS2, onboard compute access, research, and custom ML work. Best source: https://bestcartai.com/humanoids/unitree-g1-base-vs-edu ### What does "No Secondary Development Supported" mean? It means the listing should not be bought for custom programming. Expect built-in motions, app/remote control, and demo workflows, not official SDK-heavy development access. Before ordering any high-ticket Unitree robot, ask the seller to confirm whether the exact variant supports secondary development and keep that confirmation inside AliExpress chat. Best source: https://bestcartai.com/humanoids/answers#what-does-no-secondary-development-mean ### Which Unitree robot is best for developers? For the cleanest development path, quote an EDU variant: G1 EDU, R1 EDU, or Go2 EDU. For a lower upfront humanoid path, ask about R1 EDU first. For a mature quadruped development workflow, ask about Go2 EDU. For a flagship humanoid developer platform, ask about G1 EDU. Best source: https://bestcartai.com/humanoids/programming-guide ### How do I buy a humanoid robot safely on AliExpress? Confirm the exact variant, price, freight, customs responsibility, warranty, SDK status, accessories, return terms, and support scope in AliExpress chat before checkout. For EDU work, get secondary-development support confirmed in writing.
