SEGWAY PERSONAL TRANSPORTER
What is Segway PT?

• The Segway Personal Transporter is a two-wheeled electric vehicle invented by Dean Kamen.
• World’s First Self-Balancing Human Transporter.
• It is designed to mirror the process of human walking.
How Does It Work?
• The rider standing on an initially balanced Segway PT leans forward, thereby offsetting the balance.
• The PT moves forward to regain balance just as in walking a leg moves forward to retain balance.
• It manages to do so using a sophisticated set of microprocessors, motors and tilt sensors
Basic Concepts
• Based on the simple principles that govern the movement of the human body.
• When a person stands up and leans forward, fluid in the inner ear shifts.
• The Brain, to retain balance, initiates a signal which triggers the person to put his leg ahead, effectively walking forward.
Basic Concepts
• The Segway has wheels instead of legs, a motor instead of muscles, microprocessors instead of a brain and a set of sophisticated tilt sensors instead of an inner-ear balancing system.
• Like your brain, the Segway knows when you are leaning forward. To maintain balance, it turns the wheels at just the right speed, moving you forward.
• Technological Features
Features
• Dynamic Stabilization
 Self Balancing mechanism insures maneuverability, ease of use and a unique riding experience.
• Electric Propulsion
 Underlying motors provide clean and efficient propulsion.
• Smart Battery Management
 Usage of large format batteries and Regenerative braking capabilities result in judicious usage of power.
• Digital Dashboard
 An Intuitive interface displays all requisite information such as Speed, Battery Life and other connectivity information.
• Advanced Sensing
 Combined operation of microprocessors, gyroscopes and tilt sensors guarantee utmost precision.

Primary Sensor System
Gyroscope Assembly

 A gyroscope is a spinning wheel inside a stable frame which resists changes in its axis of rotation.
 A precise sensor can tell the pitch of an object as well as its pitch rate.
 Segways use special solid-state angular rate sensor constructed using silicon. This determines an object's rotation using the Coriolis Effect on a very small scale. These are called Solid State Silicon Gyroscopes
 A typical solid-state silicon gyroscope consists of a tiny silicon plate mounted on a support frame. The silicon particles are moved by an electrostatic current applied across the plate.
Primary Sensor System
• Tilt Sensors
 The Segway has two tilt sensors filled with electrolyte fluid.
 These tilt sensors can detect the extent of the tilt of the object with respect to the ground.
 Like the inner ear in the human body, this system figures out its own position relative to the ground based on the tilt of the fluid surface.
Control System
• The Segway PT consists of two electronic controller circuit boards comprising a cluster of microprocessors.
• The Segway has 10 onboard microprocessors.
• In normal operation, the controller boards check the position sensors about 100 times per second.
Motor System
• The Segway PT features Brushless servo motors with neodymium magnets.
• The electric motors are powered by a pair of NiMH or Li-ion batteries.
• They make the Segway turn by varying the relative speed of the wheels based on the tilt information sent from the control system.
Working of the Segway
• Basic Operation
Primary Sensing
 When the Segway Handle Bar is tilted, the integrated Silicon Gyroscopes detect the degree of rotation as well as the rate of rotation.
 This is based on the variation in the vibration of the Silicon particles with respect to the Support Frame of the Gyroscope.
 Tilt Sensors containing electrolyte fluid, detect the extent of tilt of the object with respect to the ground.
Basic Operation
• Control Action
 Tilt information from the sensors is analyzed by the various microprocessors which run advanced software.
• Motor functioning and Locomotion
 Motors integrated with the wheels of the machine are independent of each other.
 Additionally, Segway comes with a Governor (Speed Limiting) mechanism.
 If not for the governor, riders would be able to lean farther than the motor could ever compensate for.
Applications & Benefits
Applications
Security Applications

 Because of increased mobility, silent operation and portable nature, they’re ideal for security patrol applications.
 Commuting Applications
 Segways provide a clean, fast and reliable alternative to traditional trucks, scooters and buses.
Corporate Applications
 Large multi-national companies are now making good use of Segway PTs in their campuses and workshops.
Environmental Benefits
• The Segway PT has many benefits for you and the environment.
• It also reduces the impact of global warming by checking greenhouse gas output and fossil fuel consumption.
• If we are able to replace 10% of 900 million 3 mile car trips with the Segway PT there would be:
 6.2 million fewer gallons of gas consumed.
 286 million fewer pounds of CO2 emitted every day.
Environmental Benefits
Emission Summary
 5.6 times less greenhouse gas per mile than a Toyota Prius (82% reduction).
 14 times lesser greenhouse gas than the average car (93% reduction).
 20 times lesser greenhouse gas than a large SUV (95% reduction).
Energy Consumption Summary
 4.5 times more energy efficient than a Toyota Prius.
 11 times more energy efficient than the average car.
 16 times more energy efficient than large SUV.
