using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    public ArticulationBody ab;

    void Start()
    {
        ab = GetComponent<ArticulationBody>();
    }

    // Get the velocity of a wheel, specified by its position in local space.
    Vector3 CalcWheelVelocity(Vector3 localWheelPos)
    {
        return ab.GetPointVelocity(transform.TransformPoint(localWheelPos));
    }
}
