[GaryVoshol]

[G30] gives a tipped over robot protection from being touched by an opponent for 10 seconds. (Other rules apply after that; you can't indiscriminately "kick'm while he's down".) [G30] also implies that you can try to right yourself or get help from an alliance partner to get back on your wheels.

However, with the 14" appendage limit, it is extremely unlikely that you will be able to get enough leverage to get back up.

Short answer - you sit there and watch the rest of the match.
