R106       Horizontal extension – one direction at a time. ROBOTS may not extend beyond their ROBOT PERIMETER in more than one direction (i.e. over more than 1 side of the ROBOT) at a time. The extension may not reach outside the projection of that side of the ROBOT PERIMETER.
For the purposes of this rule, a round or circular section of ROBOT PERIMETER is considered to have an infinite number of sides. Exceptions include:

A.      BUMPERS

B.      Minor protrusions excluded from the ROBOT PERIMETER per R101

Teams are responsible for maintaining compliance with expansion limits and subject to violations listed in G413 for any violations during the MATCH.

G413 includes an exception for MOMENTARY actions that are not used for strategic benefit such as a wire or cable tie swinging out of the ROBOT PERIMETER, including while an extension is deployed out a different side.

Examples of compliance and non-compliance of this rule are shown in Figure 8‑3.

Yellow bars represent the limits of the ROBOT PERIMETER and are drawn in the same orientation of the ROBOT’S PERIMETER.

Green bars represent a measured extension from the ROBOT PERIMETER that does not exceed the limit defined in R105.

-        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 does not violate this rule

-        ROBOT D does not violate this rule as the additional extension is MOMENTARY and is not used for strategic benefit

-        ROBOT E does not violate this rule

-        ROBOT F violates this rule for extending in more than one direction by extending over a round segment of ROBOT PERIMETER.
