I'm unsure whether or not our solution to gaps in the line would result in a lack of progress or if we are good. Our solution consists of Rolling forward hoping to catch the line, and roll backwards to the start of the gap if it misses. Under 3.6.1 b the rules state
"A lack of progress occurs when: the robot loses the black line without regaining it by the next tile in the sequence
(see figures after 3.6.7)."
And after 3.6.7 example figures are shown. The one in particular that I'm interested in is
"The robot loses the black line. And the robot advanced adversely it is lack of progress and return the entrance"
My question is basically if the robot rolling backwards to the start of a gap and adjusting its angle relative to the gap would result in a lack of progress or not. Also, is there any limit to how far back it is allowed to go after finding the line.
