Design and Fabrication of Segway

Project Requirements:

The things we should plan to achieve is reduced cost of fabrication since Segway’s are very costly and safety of the driver should be the top priority with less maintenance and a stable vehicle which can be relied on for any transport activity. And before fabrication, the design of the Segway should be done for which a basic knowledge of designing is required, and there are few components which will be required in the project:
1. Gyroscopic sensors:These sensors will be used for balancing of the Segway and will take input from the handlebar.
2. Accelerometer Sensor: these will be used to determine the speed of the vehicle.
3. Frame and a Plywood board:for placement of all the components and place for the driver to stand.
4. DC motors and batteries: motors with efficient gear reduction ratio prefer (1:50) motor having 12V DC 1440rpm.
5. Wheels and handlebar: for movement.

Project Implementation:

Implementation will start with designing of the Segway and if the design is safe proceed with fabrication:
1. Determining the Rolling Resistance and Grade resistance.
2. Determining the Acceleration force and total traction effort for movement.
3. Using the total traction effort find out the wheel motor torque and calculate the maximum torque and find out the power for operation.
4. Based on power of operation we can select the batteries and motors.
5. Once all this is done do the necessary calculation for shaft bending moment and torsion and once the shaft is chosen determine the bearing used for the operation.
6. Once all the Calculation and design is done start with fabricating the frame and mount all the components at appropriate positions.
7. At the end mount the shaft with bearing and fix wheels and test the operation of the Vehicle.
