I am doing my final year project of a autonomous robotic car. Its size is 3.3feet by 5 feet and its weight is approx. 60kg. My mechanical assembly is almost complete. Its a four wheel vehicle with rear wheel drive and front wheels for steering. But I have a problem regarding steering servo.
Plz help me how to find the torque requirement for steering and which servo is best for me. Also tell me, is one servo enough or should I go for two servos?
Plz do reply its very urgent coz the completion date is 4th April, 2009.
Thanks in advance.
