i used to to the same thing...so using this concept i would just take a powered wheel with a suspension system (gas spring pushing down, while the wheel is pivoted) and have a hook at the correct elevation to "catch the hoops"
with this concept you could literally drive around a field of hula hoops grabbing all of them as you drove.
