Hi from Spain.
We are 16 years old students and we are going to construct a 1:1 electric kart. We are going to use an electric direction in order to control it with arduino. We have found three options:
35 kg servos... Easy control for us, cheap but, would they be powerful enough? are really 35kg? what about the durability?
pinion rack with high torque 12v motor. Difficult for us to construct, medium control, more A.., medium/high durability...
linear actuators, not too expensive, ¿? difficult for us, high durability but not too high speed..
We are going to move the direction and the arduino with a 3s lipo battery
Could anyone help us? Which option do you think is the best?
