Codename: Bhai Sahab 2.0

What we need:
  1. Wheels
  2. Motors
  3. MEMS Accelerometer & Gyroscope
  4. Motor Controllers
  5. Batteries
  6. Lots of nuts&bolts,transistors,resistors,diodes,microcontrollers....

and all that in Karachi, the hub of Pakistan :)
Cost -  high Rs. 50,000 maybe more... but certainly not this:
Enough has been said on gyros and accelerometers by everyone who tried making a balancing vehicle/robot. First thing ordered is the IMU Combo Board - 3 Degrees of Freedom - ADXL203/ADXRS613 from creative electron, a sparkfun distributor here in Pakistan.

What actually restricts the design are the motors. Motors capable of carrying a person's weight are not really easy to find, it's wise to find the motors and make your design around it. Here's what's possible
-Wheelchair Motors (110 - 120 rpm) - can be trusted for carrying a person
-Survey Shershah scrap market for geared motors (unreliable, impossible to find two motors exactly same)
-Use motors,chain-sprocket used in electric scooters

Thinking about thinking

Got any ideas about where students make the best projects in the world ? MIT ?
and we have the idea of a self balancing vehicle :D If you cant find it, Learn To Google (LTG) :P

So this is it, simply put: A segway !

And we're supposed to make it ? Yes!
Can we ? If so many people can, surely, we can too.
How ? Good question !

Inception ;)

There are Final Year Projects, there are hobby projects and then there's a combination of both. We - ABA, WH and UR - decided to make one such project in March 2012. And here we go.....
