Why doesn't the Line-following Sensor work?

Please: 1. Make sure the distance between Line-following sensor and line-following map is between 1-2cm, this is the best working range. 2. Do not use Line-following mode under strong light. Strong light will interfere the function of Line-following Sensor. 3. Make sure to use unreflecting material to make your own line-following map.

Why cannot the software read the value of sensor?

Please check your wiring, make sure sensors are connected to the same port with your program in the WeeeCode software.

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:When I turn on the robot, my robot has no response, why?

Q:When I controlled the robot to move forward, it moved backwards. How can I fix this?

The wiring of the motor is connected reversed. Please reconnect.

Q:How to program my robot or restore the factory setting of my robot?

Please download WeeeCode software on our website, connect robot to PC via USB cable, select serial port 'COM x' and main-board type in software to start coding your robot. 'Restore Firmware' menu offers different options: 'Online Firmware' support you make live testing of your program, robot will response immediately; 'Factory Firmware' will resume the factory program and settings for your robot; 'Mobile Firmware' supports robot control and program on WeeeMake APP

Q:I cannot connect robot to computer via USB cable nor wireless way, how can I fix it?

Your computer hasn't installed the driver of the mainboard. Please install driver in WeeeCode software 'Help' menu, restart the robot, and connect to computer again.
