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
