Segway Human Transporter Developed with The MathWorks Tools

4/23/2003 - The MathWorks announced the successful application of its tools in the development of the SegwayTM Human Transporter (HT). Segway LLC's self-balancing, personal transportation device was refined from early, conceptual designs to a reliable, durable product using MATLAB®, Simulink®, and MathWorks toolboxes and blocksets.

MathWorks products were integral to the design process for developing the Segway Human Transporter (HT), a self-balancing, personal transportation device that's designed to operate in any pedestrian environment.

The Segway HT is the first electric powered transportation machine with self-balancing capabilities. At the core of the Segway HT's dynamic stabilization technology is its inertial balancing system, which was thoroughly modeled and verified using MATLAB and Simulink. Due to the innovation of this first of its kind product, Segway LLC turned to The MathWorks for versatile software tools to address unique engineering challenges and ensure that the Segway HT would meet its lifecycle goals, reliability standards, and performance metrics.

John Morrell, Segway's Dynamics and Software Manager stated, "MATLAB enabled us to get rapid, visual representations of data, which were extremely valuable for solving critical design problems. Without the iterative process to view the results, our algorithms would have been difficult to develop. MATLAB is an integral part of our product design process. It allows us to make the technical story clear so that we all understand how the system is operating."

Using MATLAB, engineers were able to run extensive tests to verify specific performance and durability goals, as well as the mechanical integrity of the product. As part of product development, Segway's engineering team relied heavily on MATLAB's modeling capabilities to visualize various performance aspects of the battery system. With the ability to model the battery, motor, and actuators, engineers were able to understand the electro-mechanical dynamics of the propulsion system and accurately identify design challenges early in the testing phase, prior to production.

Segway's engineers chose MathWorks tools based on previous, first-hand experience using them in aerospace, automotive, and medical applications. MATLAB and Simulink enabled the Segway engineering team to design signal processing and control algorithms, evaluate the dynamic and mechanical performance of the Segway HT, and create algorithms for fault detection and response.

"MATLAB and Simulink have become fundamental tools for engineers and scientists worldwide, throughout multiple industries, to develop products that enhance people's everyday lives," said Richard Rovner, vice president of marketing at The MathWorks. "Segway's choice of The MathWorks tools speaks to the flexibility of our products and our commitment to working with innovative companies to make ideas a reality."
