Indian Institute of Technology Hyderabad 2 WHEEL SELF BALANCING BOT By Avinash Kommineni, Sai Kumar Reddy.

Segway Robot  These are basically self balancing robots.  They balance themselves by translating themselves to and fro.  Their motion will be sensed by using a sensor.  The sensor used is called accelerometer sensor.  The sensor is to be combined with a micro controller to be used.  The microcontroller must be programmed in a way so as the robot translates to maintain its balance on receiving inputs from the sensor.

Uses  They can be used in such a way as to travel forward or backward.  They can even be used as vehicles by humans.  It works irrespective of irregularity of surfaces.  The current day short distance usage vehicles can be substituted by them.  It is extensively used in military.

. Our Project  In our project by using an ATMEGA8 microcontroller we are interfacing the accelerometer sensor.  The microcontroller is attached to the chasis of the robot.  The program has to be written into the microcontroller in such a way that the tilting of robot sensed by the sensor should be balanced by the motion of robot in respective direction.  The motion required can be provided by using two small motors attached to the wheels of the robot.
