krOnchBot - guiding my first steps into robotics

Hi! I am a recent robotic hobbyist and started learning this week only. So pardon my simple designs. With the limited time and material that I have at my disposal, I was able to make this current robot. The basic structure rests on a computer "mouse" to which I have added few CDs as wheels. I call this "krOnchBot" - which is a character of Hindu mythology - mouse of Lord Ganesh. Thus compiling the east and the west.

Materials needed

• 1 x Arduino uno
• 1 x Servo
• 1 x L293D motor driver
• 2 x Geared motors
• 1 x Sharp GP2D12 analogue distance sensor
• 1 x Computer mouse
• 4 x CDs
• 2 x Bottle cans
• 2 x Batteries (9V, 6V)
• 1 x Battery holder
• 2 x Battery connector
• 6 x Jumper wires: male to male
• 1 x USB cord
• 1 x Glue gun
• 1 x Soldering iron
• and a little bit of imagination.

Just be sure that sometimes the code for motors need a change as one might connect them to alternate motors.

Thanks to all the community members for their vluable posts and detailed model designings. Hope to make something better and useful.
