Minotaur is one of my favourites too.
I skip past all of the theatrics bullshit in the episodes to get right to the fights, I don't even watch the bit about the teams, but 9/10 times you can choose the winner just from looking at the design of the robots as they sit there before the battle. Minotaur is one of those robots you know will do well, just a very simple design, executed well. The little front ramps seemed to hinder it as much as it helped in its last fight, but they maneuvered it so well.
A lot of the spinners are really poor designs, bad weight distribution, or overengineered designs that don't work well in practice against other bots, bad armour, but Minotaur is exactly what it needs to be in a small, solid package, not a thing more.
