Sawbot
Sawbots are close to spinners because they do have a spinning weapon.
But contrarily to spinners or drums that features bars/discs/tribars, a sawbot's weapon is just (as the name implies) a saw or circular weapon (single component) attached to a motor. Middleweight and heavyweights can have multiple saws.
Sawbots suck in Stock RA2, but they can be very efficient in DSL.
Ninja, BOT-204 (and their DSL counterparts) and Spinner from the West are sawbots, but Ripblade isn't one because it has teeth on a disc, and this applies to both DSL and Stock.
Sawbots do generally less damage per hit than classical bar/disc spinners and have generally more fragile weapons, but they do continuous damage, have lighter weapons, and their weapons can't generally be stopped. Also, if it loses one of it's saws, a sawbot won't wobble like a normal spinner would.
Your sawbot can be either damage-orientated (use classic sawblades or Backlash discs) or strength-orientated (best choice is WhirlWep discs but you can also use chewblade saws). Damage-orientated sawbots are extremely powerful but have vulnerable weapons, and vice versa for strength-orientated ones.
A TWM3R is a good choice for a classic sawblade, but for heavier discs like the chewblade you'd be better off with stronger motors, especially since the disc CAN be stopped as it's not perfectly circular (toothed weapon).
Pros:
- Damage is constant. The sawbot wil accumulate points as long as the blade is in contact with the opponents chassis.
- Blade is virtually impossible to stop when it contacts. Much like a grinding drum weapon.
- Blades are only one piece, so bot doesn't spin out of control when it breaks off the bot.
Cons:
- Weapons are fragile.
- The power of the motor must be efficent to ensure decent damage.
- Size and weight of the bot affects the effectiveness of the bot.
