FRC | Telescoping + Flipping Hook
This telescoping tube was designed to maintain a low CG while still being able to hook onto high features. It uses radial roller bearings between stages to minimize friction. Constant force springs extend the telescoping stage and the flipping stage is sprung such that when the telescoping stage is released the flipping stage is actuated. This design accomplishes the same task as a two-stage telescoping hook however allows for large misalignment of the hook when grabbing; the flipping stage pivots until the hook reaches the desired hang component.
