I guess as long as the minibot's starting position on the slope is lower than the end of the ramp on the deployment end, there isn't a net gain in energy, so it skirts around the rules.
It seems like the slope just gives the motors a break, they aren't exactly the best so it's a good idea to have them run as little resistance as possible before running up the ramp and pole.
I'd call it legal, but there's a lot of illegal things I'd try to call legal too
