Semi-random. The initial draws for the heats were made via random.org, but I manually sorted the Group Battle draws by placing each non-seeded robot into a five-row table in alphabetical order - one row for each heat. Then, I batched them into one of two groups - 'G1' and 'G2' - based on their numerical order in the table. For example, Cherub would go into 'G1' for Group Battle 1, Coyote into 'G2' for Group Battle 2, and so on.

I will definitely consider Hobgoblin and Jellyfish's control problems, Toast, and thanks for letting me know about Cobra's anti-spinner wedge in advance. Should make the latter's Group Battle particularly interesting.
