TTS Group is a leader in developing innovative learning tools for educators and students worldwide. Recognizing the growing importance of computational thinking, TTS had a clear vision for Oti-Bot—a child-friendly robot designed to simplify coding while integrating AI, creativity, and hands-on learning in the classroom. With their user research and initial industrial design completed, TTS engaged LKK Design to navigate the complex journey from a proven design to successful mass production.

The primary goal was to faithfully realize TTS's vision for Oti-Bot and ensure its success as an educational tool. Key objectives included:

• Functional Fidelity: Accurately implement specified features like programmable caterpillar tracks, line following, color sensing, and internal storage.

• Educational Alignment: Ensure the final product supports the UK Computing Curriculum for Key Stages 1 and 2, fostering computational thinking and problem-solving skills.

• Manufacturing Excellence: Transform the design into a durable, high-quality, and cost-effective product capable of withstanding classroom use.

• Technical Reliability: Seamlessly integrate all hardware and firmware components for stable and responsive performance.

LKK Design provided a comprehensive solution, focusing on engineering optimization and manufacturing execution to bring the Oti-Bot to life.

Industrial Design & DFM Review

While the core aesthetic and user experience design were led by TTS, LKK's engineering team conducted a thorough Design for Manufacturability (DFM) review. We analyzed the design for structural integrity, material selection, and assembly efficiency, providing critical feedback to optimize the product for injection molding and mass production without compromising its child-friendly and professional appearance.

 Mechanical Structure Design

Our mechanical engineering team translated the approved design into a robust and functional reality. We focused on refining key mechanical systems, such as the caterpillar tracks, to ensure optimal maneuverability across various classroom surfaces and long-term durability.

 Electronic Design

• Hardware Development: We sourced and integrated high-quality components for the sensor, camera, and motor systems. Our engineers meticulously designed the internal layout to ensure all electronics fit compactly, operated reliably, and maintained the product's balance.

• Firmware Development: LKK developed updatable firmware to manage device operations and ensure seamless communication between all hardware components. This future-proofs the Oti-Bot, allowing for new features and enhancements.

• Software Collaboration: We provided underlying hardware-software integration support, ensuring that TTS's user-friendly, block-based programming app could communicate effectively with the robot for a seamless and engaging user experience.

Prototype Making & Testing

We built and iterated upon multiple functional prototypes, conducting rigorous tests for durability, performance, and user interaction. This iterative process, informed by DFM principles, was crucial for identifying and resolving potential issues before committing to production tooling.

Mold Development & Mass Production

With the final design validated, our team managed the development of high-precision injection molds. This step was critical for ensuring the consistency and quality of every part. After securing necessary safety certifications (e.g., CE marking) and completing a pilot production run, LKK oversaw the full-scale mass production of the Oti-Bot, ready for distribution to schools across the UK and beyond.

Through our specialized engineering and manufacturing capabilities, LKK Design enabled TTS Group to successfully launch the innovative Oti-Bot to the market. We ensured that TTS's visionary design was realized as a robust, reliable, and classroom-ready product. By de-risking the production process and ensuring manufacturing excellence, we helped TTS deliver a powerful tool that makes computational thinking accessible and engaging for children, solidifying their position as a leader in educational technology.
