Needed to get acquainted with Arduino hardware and I2C interface. What better way tot do that then building a Segway.

Segway ran off dual 12V DC bushed motors linked to a Sabertooth 120A speed controller. This speed controller received serial input from and Arduino UNO which referenced a ITG3200 gyro and ADXL345 accelerometer to get readings and balance the board.

Frame was made out of aluminum tubing and parts like the steering console. battery casings, and wheel hubs were all 3D Printed using my in home FDM 3D printer and Shapeways.

Arduino Segway

Build to Near Completion

3D Printing Utilized

3/4x3/4 inch 6063 1/8 inch thick aluminum was chosen best for its lightness and sufficient strength for a purpose like this.
A complete layout of the bottom chassis laid out to visualize real estate and mounting of all components

Tight workspace lol
2 12V Lead-Acid batteries were used for power and had custom FDM printed mounts for frame attachment
An overview of one DC motors connected via chain to the SLS printed wheel hub which drives the wheel forward
Gear Ratio of 1:6 for optimal torque when balancing the system
Overview of the electronics. An arduino UNO for processing, a ITG3200 gyro provides the angular readings, and a Sabertooth 2x25 DC Brushed motor controller
2 potentiometers were also used, one for trim sensitivity (how quickly the system levels itself) and steering
