Thats one step forward and two steps back as far as rule harmonisation is concerned. The general RFL rules do not state that robots have to have an active weapon. The RFL weight limits have a 2-tier 30lb weight class; open and Sportsman which has been incorporated into the RFL ruleset from the NERC rules - this Sportsman class also puts limits on many aspects of the design including a ban on any wedge that 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.. !!
To ban boxes in this country in the way suggested does nothing for harmonisation IMHO
