You are viewing a rule from the 2023 manual. Click here to see the latest version.

G109       Don’t extend in multiple directions. ROBOTS may not extend beyond their FRAME PERIMETER in more than one direction (i.e. over 1 side of the ROBOT) at a time. The extension may not reach outside the projection of that side of the FRAME PERIMETER. For the purposes of this rule, a round or circular section of FRAME PERIMETER is considered to have an infinite number of sides. Exceptions to this rule are:

A.     MOMENTARY and inconsequential extensions in multiple directions,

B.     A ROBOT fully contained within its LOADING ZONE or COMMUNITY, and

C.     MOMENTARY movement of a MECHANISM from 1 FRAME PERIMETER side to an adjacent FRAME PERIMETER side.

Violation: FOUL. TECH FOUL if extending in multiple directions scores a GAME PIECE. If extending in multiple directions results in the ROBOT blocking all access to a FIELD ELEMENT, RED CARD

MOMENTARY and inconsequential actions include a wire or cable tie swinging out of the FRAME PERIMETER, including while an extension is deployed.

Examples of compliance and non-compliance of this rule are shown in Figure 7‑3.

Yellow bars represent the limits of the Frame Perimeter and are drawn in the same orientation of the Robot’s Frame Perimeter. Green bars represent a measured extension from the Frame Perimeter that does not exceed the limit defined in this rule. Red bars represent a measured extension from the Frame Perimeter that exceeds the limit in this rule.

All following examples are legal in ROBOT’S LOADING ZONE and COMMUNITY.

·        ROBOT A violates this rule for extending in more than one direction

·        ROBOT B violates this rule for extending in more than one direction

·        ROBOT C violates this rule for extending beyond an infinite number of sides and therefore any extension over an arc extends over multiple sides

·        ROBOT D does not violate this rule

·        ROBOT E violates this rule for extending in more than one direction

·        ROBOT F violates this rule for extending in more than one direction

·        ROBOT G does not violate this rule as long as the extension does not exceed the definition of MOMENTARY when positioned over the BUMPER corner.

·        ROBOT H violates this rule for reaching outside the projection of the FRAME PERIMETER side.

Rule G108
G108       Opponent’s zone, no extension.  A ROBOT whose BUMPERS are intersecting the opponent’s LOADING ZONE or COMMUNITY may not extend beyond its FRAME PERIMETER. Violations which are both MOMENTARY and inconsequential are an exception to this rule.
