I would say that this is illegal due to the fact that it causes a safety concern. But I searched the rules and found rule:

<G10> HUMAN PLAYERs cannot be aided by any object or ther person. Violating this rule will result in the disabling of the team’s ROBOT and the team will be disqualified.

I see the ball chute as an object and by standing on it you would be aided.
