TI DSP, Segway Human Transporter Chosen as ESC Best of Show

4/23/2003 - CMP Media has named Texas Instruments (TI) and the SegwayTM Human Transporter (HT) as finalists in its 2003 Embedded Systems Conference "Best of Show" award for the most superior embedded technology in an end-user application displayed by an exhibitor. By leveraging its leadership in digital signal processing (DSP), TI is able to help deliver truly innovative products such as Segway´s Human Transporter that provide innovation and that meet customer´s embedded control requirements.

The Segway HT leverages TI´s C2000TM DSP platform of controllers because of their small size and peripheral integration, delivering an innovative, first-of-a kind, self-balancing, personal transportation system that´s designed to operate in any pedestrian environment. The balancing system allows users to guide the transporter intuitively both forward and backward just as a person would when walking normally. The Segway HT was designed to make short-distance travel more efficient, while allowing the operator to carry heavier loads at greater distances, enabling greater productivity. The Segway HT stays upright and balanced because of a technology called dynamic stabilization. Dynamic stabilization uses inputs from solid-state gyroscopes and tilt sensors that are analyzed by the C2000 DSP controller in real time. The DSP controller then makes minute adjustments to two powerful electric motors one hundred times a second allowing Segway HT to instantaneously adjust to rider input and provide a safe and enjoyable ride.

"Since the Segway HT takes up no more space than an average person, space is an issue. The high level of performance and integration that the TI´s DSP controllers give us with on board flash, and communication and control peripherals met out strict space requirements," said Phil LeMay, Manager of Embedded Designs, Segway LLC.

Besides offering a high level of performance, each C2000 DSP integrates many functions that are used in the Segway HT system operation. Communication with other data handling devices, a vital function in such a complex system, is achieved through the on-chip bus interfaces and CAN controller. The integrated, on-board analog-to-digital converter (ADC) continually feeds digitized data to the DSP for fast, real -time, system monitoring. Segway HT´s sophisticated monitoring and control system also includes a number of TI high performance analog devices including multiplexers/demultiplexers, hex inverters, rail-to-rail quad operational amplifiers and LinCMOSTM voltage comparators.

On-board event managers, timers and pulse-width modulation (PWM) provide the versatility needed for the system´s complex motor controls and other functions. On-chip memory stores the entire code for operating the system, providing fast response and operation. TI´s emulation support using the JTAG interface simplified coded debugging, helped the Segway team develop the complex software more quickly and with maximum reliability.

Finalists were chosen for new and innovative uses of embedded technology in end products that use technology in a new or innovative way, offer higher levels of performance or that demonstrate a new approach previously not seen in the market. Winners will be announced at ESC on April 23 at 6.00pm in booth 238.
