Problem Statement
To change the motor of the wheel of the Ball Bot so that it works properly

Designing the Implementation Process
As it can be seen clearly in this video that the second wheel does not work properly. Its motor is not right as it does not spin as fast as the other ones do. It can also be seen in this video that one of the wheel is spinning slower than the other two wheel. To fix this problem, the motor of the slower wheel had to be replaced. For this the bottom of the Ball Bot had to be unscrewed. First of all, take of all of the wheels. Then take out the batteries.

The wires were finally attached, and there was no need to unscrew the whole Ball Bot. After replacing the faulty motor with the new one, the bottom was attached back and the wheels were attached back as well.

Test, Verification, Validation, and Certification
After successful installation of the working motor in the Ball Bot, it was the time to test the motor and see if it works properly or if there are still some problem. The Ball Bot was run without any program and it worked perfectly. This video shows how the fixed motor worked. It worked perfectly. All the wheels spin perfectly and at the same rate.

Next Steps
A very important progress was made in this process. The next steps include:
 * Working on the head of the Ball Bot
 * Showing how the eyebrows lift up as the head pops up and the ears come out
 * Fixing the LEDs as they are very dim and can't be seen through the glass of the eyes
 * Making the LEDs bright enough so that they can easily be seen through the glass of the eyes and the mouth
