Ask the seller for G1 EDU, R1 EDU, or Go2 EDU, and get SDK access, ROS2 support, warranty, price, and lead time confirmed in writing before ordering. For Unitree G1 specifically, the base AliExpress listing is useful for demos and app/remote control, while G1 EDU is the path to quote for SDK, ROS2, onboard compute access, or custom ML. ## Answer snippets - Can I program Unitree G1 from AliExpress? Only treat the G1 EDU path as programmable. A listing that says "No Secondary Development Supported" is for demos/control, not SDK-heavy robotics work. - What is the difference between Unitree G1 base and G1 EDU? Base G1 is the visible lower-price demo/control path; G1 EDU is the variant to request for secondary development, SDK access, ROS2, and research work. - Which Unitree robot is best for developers? Quote G1 EDU, R1 EDU, or Go2 EDU. For lowest upfront developer path, ask about R1 EDU first. - How do I buy a humanoid robot safely? Confirm exact variant, freight, customs, warranty, SDK status, and accessories in AliExpress chat before checkout. - What should I ask before an EDU quote? Ask for exact variant, secondary development support, SDK/ROS2 access, onboard compute, warranty, final landed cost, freight method, and lead time. - What should I buy with a G1? Start with the R3 remote, spare battery if available, shoes or foot protection, and event/demo accessories if needed. ## Embed integration Publishers can embed product banners on their sites: ```html ``` Or use the JSON API: ``` GET https://bestcartai.com/api/embed?q=wireless+earbuds&tag=YOUR_ID&format=json ``` ## Who runs this BestCart AI is part of the Endorso affiliate network (https://endorso.com).
