Disappointed not to see anything about Blendo, a 500rpm spinner from the mid and late 90s which, despite having a poor drive system, caused so much damage that it was twice disqualified due to insurance liability. Blendo was designed by Jamie Hyneman and Adam Savage, who as we all know went on to do nothing of importance. As I understand it, Blendo had a profound impact on the design of later robots.
Full body spinners are still a thing, see Gigabyte and Captain Shrederator. Unfortunately, their performance tends towards "middling" due to control and reliability issues.
The full body spinners struggle to keep spinning, as the forces of impact tend to ping-pong them around the arena. As long as their opponent can tank a hit and has a halfway competent driver, the spinners tend to end up corralled in a corner.
The latest season has an absolutely incredible match between Gigabyte and Hypershock.
While I'm still catching up on the modern incarnation (I just hit the post-season of the 2019 season, second one on discovery), you've also got the ones that are a sort of evolution of full-body spinners. In particular, Son Of Whyachi pretty consistently sends opponents flying or rips them apart without the stability/reliability issues of a Gigabyte or Shrederator. Bloodsport has also done some pretty solid damage with a smaller form-factor than Gigabyte during the 2019 season. They tend to be extremely chaotic fights.
I think my favorite example of the problems with class full-body spinners was in 2018 when an opponent managed to rip Gigabyte's outer shell off in one piece.
