The Transporter

 Steering is a crucial part of the application of this two-wheeled Transporter  We developed a gas piston force-feedback resistance system for turning our Transporter, allowing for smooth operability  Accelerometer is located at handlebar height for increased accuracy in reading user input

Lean Steering – Gas Sturts

 By simply leaning, a user will accelerate forward or backwards depending on the movement  An accelerometer and gyroscope are both located on the bottom of the Transporter for accurate readings  The computer can display the pitch and acceleration of the different sensors through the ZigBee signal

 User will be able to place tag near reader to use the Transporter  Safety precaution and security measure  The PIC processor will detect input from an RFID reader when appropriate tag is used
