12 Lb Sportsman class robots are bots the focus heavily on speed, and design, and drivability. An active weapon is still required but it must be something like a crusher, flipper or hammers. no exposed spinning weapon is allowed.

Bringing Spare Batteries is HIGHLY encouraged. Bot's get a minimum of 20 minutes in between matches for repair and recharge. Rarely is this enough time to recharge a fully dead battery. Bringing spare batteries is highly recomended!! If you let the organizers know your battery size and connector type one week in advance (firstname.lastname@example.org), we will glady provide you with a spare battery for your bot for free. NHRL has a strong prefrence for XT style connectors XT90/60/30.
