carpet perimeter depicted in Figure 2.3.

And

G36
During the MATCH, TEAMS must be within their ALLIANCE STATION. Exceptions will be granted for inadvertent or inconsequential infractions and in cases concerning safety.
Violation: FOUL

So I would say, No, the human player definitely can't use any mechanism to help throw discs. Even if these rules aren't explicit enough, it doesn't seem like Gracious Professionalism to do such a thing, IMHO.
