Hello everybody,

Well I'm a level 4 mechatronics students from Mauritius and doing my project on a self balanced bicycle which uses a flywheel to achieve this.A better view of it can be seen on:

http://www.youtube.com/watch?v=0312B...eature=relatedhttp://www.youtube.com/watch?v=AvGUu...eature=relatedDuring the past 3 weeks,I've been struggling on calculation of torque(flywheel motor) and I'm stuck.

I have been using the formula T=J*alpha,

where J=moment of inertia and alpha=angular acceleration.

I have assumed overall mass of prototype to be around 2.5 kg,radius of flywheel=5 cm,mass of flywheel=0.5kg,radius of driving wheel=5 cm,max permissible tilting angle=30 degrees.

Could you please help me in selecting my 12V DC motors:flywheel motor(rpm,torque)

Driving motor(rpm,torque)

and flywheel specifications(radius and mass)

and finally if gear box(reduction gear) is needed,its ratio??

Thanking you all in advance.

Best regards
