Turning a model car with no steering.

  1. Feb 27, 2014 #1
    Hi Guys,
    If I were to build a model car, with each wheel having it's own servo, then how can I make it turn in one direction.
    Say if I want to turn left, if I cut power to the front left and reduce the speed of the rare wheels will the front left wheel act as a pivot? Or should I cut power of the whole left side?
    Is there anyway I can simulate this?

    Welcome to PF.
    The skid steer loader has 4WD without directional wheel steering. The best geometry to use is a wide vehicle with a short wheelbase as that reduces tyre wear while turning.

    Different speeds for each wheel will steer the car.
    Omni wheels will completely eliminate wear from lateral motion without the need for a conventional differential or accommodations for Ackerman steering geometry.
