A lifter has many advantages in the current arenas. Being able to gently roll a robot up against a wall can immobilse it. At Barnsley, Cabrakan could rest immobilised on its side, but this only happened once because the CO2 flippers are too powerful to be accurate. A flipper is good at getting a robot OTA, a lifter could be good in other ways. Thinking about putting one on my heavy, and Cabrakan will have one in the future too.
