Why is the Line-following Sensor not working?

Ensure the sensor distance to the line is 1-2cm. Avoid using it under strong light which causes interference. Use non-reflecting material for your line-following map.

Why can't the software read the sensor value?

Check your wiring connections. Ensure the sensors are plugged into the same port specified in your program within the WeeeCode software.

Do you offer customization services like OEM or ODM?

Yes, we offer customization services including OEM and ODM. Please contact us for more details regarding your specific project requirements.

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.

Product Q&A

Q:Why does my robot have no response when turned on?

Check if batteries are low and need recharging or replacement. Ensure batteries are installed with correct polarity (+/-). Verify wiring on the battery holder or motor is correct.

Q:How can I fix the robot moving backwards when commanded to move forward?

The motor wiring is likely connected in reverse. Please disconnect and reconnect the motor wires to correct the direction.

Q:How do I program the robot or restore factory settings?

Download WeeeCode software, connect the robot to PC via USB, and select the correct serial port and mainboard type. Use the 'Restore Firmware' menu to choose between Online, Factory, or Mobile firmware options.

Q:Why can't I connect the robot to my computer via USB or wireless?

Your computer may lack the mainboard driver. Install the driver via the WeeeCode software 'Help' menu, restart the robot, and reconnect it to the computer.

Q:Why doesn't the robot move when powered by USB?

USB power only supports the chip and sensors. To drive motors or servos, you must connect the batteries and switch on the power button.
