R101       *Frame Perimeter must be fixed. The Robot (excluding Bumpers) must have a Frame Perimeter, contained within the Bumper Zone and established while in the Robot’s Starting Configuration, that is comprised of fixed, non-articulated structural elements of the Robot. Minor protrusions no greater than ¼ in. (~6 mm) such as bolt heads, fastener ends, weld beads, and rivets are not considered part of the Frame Perimeter.

R105       Robot extension limit. Robots may not extend more than 48 in. (~121 cm) beyond their Frame Perimeter.

H102       *Enter only 1 Robot. Each registered FIRST Robotics Competition team may enter only 1 Robot (or “robot,” a robot -like assembly equipped with most of its drive base, i.e. its Major Mechanism that enables it to move around a Field) into a 2023 FIRST Robotics Competition Event.

R104       Starting Configuration – max size. A Robot’s Starting Configuration may not have a Frame Perimeter greater than 120 in. (~304 cm) and may not be more than 4 ft. 6 in. (~137 cm) tall.
