Why can't the robot connect via USB or wireless?

Your computer may lack the mainboard driver; install it via WeeeCode's 'Help' menu, restart the robot, and reconnect.

Why doesn't the robot move with USB power supply?

USB power only supports the chip and sensors; you must connect batteries and switch on the power button to drive motors.

Why doesn't the Line-following Sensor work?

Ensure the sensor is 1-2cm from the map, avoid strong light interference, and use non-reflecting materials for the map.

Can I get a customized robot for my project?

Yes, we offer OEM and ODM customization services including customization from samples, designs, or full customization.

AI-Powered supplier vetting

SummaryWeeemake Steam Tech Co., Ltd. is a Shenzhen-based Chinese factory established in 2018, focused on STEM education robot kits, AI maker-space kits, and interactive AI solutions. The supplier reports five production lines, annual capacities of 10,000 AI Interactive Demonstration Solutions and 8,000 STEM Robot Kits, and off-peak lead times within 15 working days. It exports domestically and to Europe, with exports representing 41%–50% of sales and self-operated import/export rights. SGS conducted an audit with a report validity period from May 28, 2025 to May 27, 2026, but the recorded audit result is not interpretable from the provided value. The company states that it provides OEM/ODM and multilingual customization, supported by 11 years of R&D engineer experience and 6–10 quality-control staff. No management-system certification is listed, while after-sales, financial credibility, customer cases, and several operational controls remain insufficiently evidenced.

Supplier typeThe supplier is identified as a factory and a limited company located in Nanshan District, Shenzhen, Guangdong, China. Its registered business information and company descriptions support classification as a manufacturing-oriented supplier rather than only a trading entity.

R&D capabilityThe company describes itself as an R&D-focused high-tech enterprise working in STEAM education, artificial intelligence, and interactive technology, with a complete product-development process and 11 years of R&D engineer experience. However, specific new-product, SDK, or other innovation capability fields remain unknown, so the evidence supports an innovation orientation but not a complete capability assessment.

Production capacityThe supplier reports five production lines, annual capacity of 10,000 AI Interactive Demonstration Solutions and 8,000 STEM Robot Kits, and a stated off-peak lead time within 15 working days. Its described process covers development, design, procurement, SMT mounting, welding, testing, packaging, and delivery, providing explicit evidence of established production capability.

Customization capabilityThe supplier explicitly states that it provides OEM/ODM services and supports multi-language content customization. Although the dedicated ODM and OEM capability fields are marked unknown, the company description directly supports the availability of customization services.
