30-lb Sportsman Class1. A 30-lb robot may be entered in the €œSportsman€ class if it complies with the additional rules in this section. Any 30-lb robot may be entered in the €œstandard€ 30-lb class.
2.2.1. Intent. The intent of the Sportsman Class is to encourage novel designs and driving ability. The focus of this class is fun and creativity, not the annihilation of your opponent. Robots must comply with both the letter and spirit of these rules to qualify for this class.
2.2.2. Active Weapon Required. Sportsman class robots must have an active weapon. This is defined as a weapon or device intended for use in attacking the opponent, independent of the robot drive train. These include but are not limited to lifters, hammers, clamps, flame weapons and spinning weapons (within the limitations specified in 2.2.3)
2.2.3. Limitations on Spinning Weapons. Spinning weapons [are allowed] at this event. [Enter any additional restrictions or explanatory text regarding limitations here.] If allowed, weapons that can rotate continuously are permitted if and only if the edge/tip velocity does not exceed 500 surface feet per minute (SFM). Weapon SFM will be determined by tachometer prior to the start of the event using this formula:
SFM = RPM * ÀD
Flywheels and other spinning parts internal to the robot are allowed without limit, but may not act directly as weapons. For example, a flywheel-powered

hammer or axe would be legal if the weapon arm did not move more than 360 degrees.
2.2.4. No Wedges. A €œwedge€ is any part of a robot that in any position is capable of elevating a flat sided box with ¼€ of ground clearance more than ½€ off the floor simply by sliding the wedge under the box when the robot in question is in any €œnormal€ driving positions e.g. with its wheels on the floor.
2.2.4.1. Large plates extending from the robot that are flat or nearly flat to the floor are not allowed.
2.2.4.2. Other static devices which have the purpose of removing the opponent€Ÿs wheels from the arena floor are not allowed.
2.2.5. Lifting, Flipping and Grabbing Weapons. An articulated €œspatula€Â, parallel to the floor is allowed, provided that:
ï‚· It complies with the €œno wedge€ rule (2.2.4) and
ï‚· It is no more than ¼ the width of the robot (as measured across the wheels at their widest point) and
ï‚· It extends no more than 6€ from the front edge of the robot.
2.2.6. Excessively Destructive Weapons. Weapons deemed too destructive by virtue of their mass, MOI or other characteristics may be further limited or disallowed at the discretion of the event. Please contact the event organizer concerning your design to avoid problems.
2.2.7. Standard RFL Rules Apply. Unless otherwise stated, all other standard RFL rules will apply. This includes walkers and their weight bonuses. However, a walker that uses the weight bonus for a spinning (or other) weapon that is too destructive will be disqualified.
