Why doesn't the Line-following Sensor work?

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

Why can't the software read the sensor value?

Check your wiring to ensure sensors are connected to the same port specified in your program within the WeeeCode software.

Is customization available for projects?

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

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 the robot have no response when turned on?

Check if the voltage is low and recharge or replace batteries. Ensure batteries are installed with correct polarity and wiring is correct.

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

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

Q:How to program the robot or restore factory settings?

Download WeeeCode software, connect via USB, and select the correct serial port. Use the 'Restore Firmware' menu for Online, Factory, or Mobile firmware options.

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

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

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

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