I couldn't believe my eyes too, until I heard that fans were allowed. Gravity and ground/tire friction are the two biggest limits for going very quickly around a track (it's basically a one way track with many wrong branches) aero down force is one way to break the limits but with big aero drag penalty and only works at high speeds. fans can be extremely efficient if road surface is quite flat. the tighter the "seal", the less airflow you have to extract, and the less power you're losing. of course active aero is a big step forward that has been banned too. it would be fun to see micro mouse with active aero, don't know if the speeds are high enough to make a difference though...especially compared to a fan that allows 6Gs

@ntray3729 I think he was merely pointing out that IF the progress slows down, robots converge and competition starts becoming boring because everyone has similar algorithms and hardware and just beat each other by microseconds depending on a spec of dust being in the way or not, or having a fan that gives you 5% better suction force, there are possibilities to make slight adjustments to the rules that would make the problem even more complex and bring new ideas. (curved) corners, ramps, levels, or even drones in a 3d maze... The cool thing is that even with a different problem like lapping around a miniature track, with not so many changes, they could probably be very good and quickly beat any mini rc car. The fan trick has been banned from all racing classes but it's coming back in an EV (speirling) that is both road legal and can beat Formula one around a track while being 10x less expensive, and would destroy a formula E
