Hello,

Your project sounds like fun. Can you provide any more information? What type of environment will the robotic car be traveling over? Is this a road vehicle? Will it be expected to go up and down hills? How fast do you want it to travel. Are you going to build it or is this a design exercise. How much do you expect the person to weigh? That will give you the amount of weight you have available for your chassis and what not.

there's a motor calculator on this site that will give you a good place to start.
For a ball park, look at the specs on motorized wheel chairs or golf carts or a segway, depending on what type of ground you want to cover.

Dear Conscripted

Thanks for being concerned.
Actually I am trying to build a chair car which uses a line follower to manuver automatically.
This will have practical application in hospitals.
The chair car is supposed to move on the hospital floor.
The angle of inclination is 0 degrees.
I expect it to move around with a velocity of 3 to 6 feet per second.

Awaiting a positive reply :-)

Sounds like starting with a motorized wheel chair will get you over half-way there.
You'll just need sensors, a processor and motor control.
