Auto Balancing Human Carrier
The purpose of this project is to build “Auto-Balancing Human Carrier” which can be used as a convenient way of travelling for short distance carrying a single person. This auto-balancing human carrier consists of a platform with wheels attached to its sides, a physical application of stabilized control system. It is build loosely around the design of Segway. The rider drives the vehicle by standing on the platform and leaning in the direction to move. The handlebar also serves as steering control of the vehicle. It balances by detecting the tilt angle using an accelerometer and gyroscope, calculating the corrective action using a controller implemented on Arduino to move forward or backwards automatically to regain its balance.
1) To design a vehicle that will try to balance itself .
2) It also follow the commands given by rider .
3) To design a vehicle whose components are easily accessible.
4) fabricate a environment friendly vehicle.
Project implementation includes,
1) Solidworks Model.
2) Matlab Simulations.
3) IMU Sensor.
4) Hardware Designing.
5) Problem Analysis.
Benifits of project are,
1) Design environment friendly vehicle.
2) Reduce time for travelling foot distance.
3) Cover less space for riding and parking.
4) this vehicle is good for people having difficulty in walking.
5) No need of any fuel. Just only work on battery.
Technical details includes,
1) Tilt measurement to be carried out by using gyroscope and accelerometer combined in a 6 degrees of freedom inertial measurement unit(IMU).
2) The balance as well as forward movement is controlled by the DC motors each connected to one side wheel.
3) The operations are implemented using a microcontroller.
which performs filtering,sensor fusion algorithms,PWM motor control in PID loop.
4) Steering along with continous balancing is achievable by interfacing a potentiometer with the handle .The value of the potentiometer changes as handle rotates.
5) I2C communication protocol will be use to interface IMU sensor with controller.
