sir/madam,i am doing final year project.
my project title is automated segway based wayguider.
i need to drive nearly 60kg human load plus 25kg vehicle load is (due to the use of motors,rods,pillow blocks,wooden box), totally 85kg.
the speed of my vehicle should be 10km/hr.
i am using two wheels each with radius 12.5cm
i need two separate dc motors.
specifications:
mass =85kg.
velocity=10km/hr.
how much motor rpm,torque,power,voltage and current are needed?
please guide me with some solutions.it's urgent

What are the frictional losses? Frictional losses may be determined by setting it in motion and measuring the rate of deceleration.

What is the required rate of acceleration? After overcoming frictional losses additional torque is required to increase speed.

If used outside, air drag caused by contrary wind velocity may need to be considered.

With a little interp, specs from an electric wheel chair might be usefull:
Loaded wt,kg, inc batteries = 112
Max speed = 7.5 km/h
Range 25-30 km
motors, 2, @ 250 W, 11.5 A, 22 V DC, gear reduction.
Batterys, 2 @ 12 V, 73 Ah
