Blueabot satisfies 2 of the three conditions for sure: it is in its own Home Stretch, and it is in possession of a Trackball.

The thing is, this will be context dependent. As in, if Blueabot stopped to hurdle before Redabot hit it, or if Blueabot's launching mechanism is beginning to fire. Those can change the situation. In the former, Blueabot is not protected; in the latter, Blueabot would probably be protected, as it is in the process of elevating the Trackball.

Neither we nor the GDC can call this one; that'll be the ref's decision in each individual match. In this case as stated, there would be a penalty on Redabot, because Blueabot is moving towards the Overpass (admittedly, not exactly willingly, which might change the call).
