Jens, thank you for your inspiring 'Single Sensor Car'.
Thanks also go to the late Jerome K Jerome for giving me a clue as to how one can survive in a maze such as this.
I have slightly modified your code to build a solver for the maze at Hampton Court near London.
Improvemts:
1.
I feel that there should be a way of indicating that the little red bug (bot) has visited the middle of the maze and returned to the start, perhaps two trigger sprites and a counter to show the number of times the little creature has completed the puzzle.
2.
Bot sometimes gets a little lost and loops back on itself, notably in the top right where I have thickened the end of the line. I feel my fix is a bit of a cludge, sort of like changing the world to make the code fit.

SpriteThis block allows you to set the pen's color, transparency (on a scale from 0=opaque to 100=invisible), or size (in pixels). The color can be set in many ways, including RGB values, HSV values, HSL values, fair HSV or HSL (based on a modified spectrum that gives each spectral color equal space and promotes brown to a color), color number, crayon, or X11/W3C color name.

}§_ext_clr_numbersNote to myself: When the user sets a fair dimension, say fair HSL, variable HSL contains the corresponding "unfair" values, and "raw HSL" contains the numbers the user actually gave. It has to be this way because in the case of HSV, there is no "HSV" variable; rather, we use the pen's actual remembered-by-Javascript color's HSV coordinates. So our HSL variable has to be analogous to that. In both cases "raw" means the numbers the user gave us.1HSV✐ raw HSL100HSV100The identity function reports its input.This block reports the pen size, color, or transparency, in all the same ways that the SET PEN block allows you to set those pen properties. (It will also report the current crayon number, if the pen color was most recently set with SET PEN TO CRAYON.)

catchtagSets the pen color
to one of 100 preselected colors, like a box of 100 crayons.
The colors have names that are meant to be evocative.
They are organized in families, more or less corresponding
to spectral (rainbow) colors; the input slot has a two-level menu
in which you can hover over a family name to see the colors
of that family, each including a crayon number and an RGB value.

values, each between 0 and 255. 0,0,0 is black; 255,255,255 is white. 255,255,0 is yellow, and so on.
The SET PEN block in this library lets you set individual red, green, or blue without changing the others, lets you provide a list of three RGB color components, and lets you provide a six-digit hexadecimal number, the form in which RGB color values are usually found online.

The SET PEN block in this library lets you set individual hue, saturation, or value without changing the others, lets you provide a list of three HSV color components, and lets you
use the very much superior HSL (hue, saturation, lightness)

See Appendix A in the Snap! Reference Manual for details.pt:a cor da caneta em RGB (vermelho, verde e azul; 0 a 255)
Reports the current pen color as a list of three HSV values
in the range 0-1.

Reports the part of the first string up to the first instance of the second string inside it. If the second string isn't found, reports the entire first string.pt:o texto de _ antes de _
Reports the portion of the first input string starting after the first occurrence of the second string. If the second string isn't found in the first string, reports an empty string.pt:o texto de _ depois de _
Reports the character position (starting from 1) of the beginning of the first input string inside the second input string.
If it's not found, reports 0.pt:a posição de _ em _
If input is TRUE, comparisons made by functions in the string library will be case-independent (so "FOO" = "foo"). This is the default.
If input is FALSE, comparisons will be exact.pt:altera comparações ignorando distinção minúsculas/maiúsculas para _
Reports the portion of the first input (string) starting at the position given by the second input (counting from 1, like LETTER n OF) and ending at the position given by the third input (also counting from 1). If the third input is empty, reports the portion from the first position to the end of the string.
If a position number is negative, counts from the end backward, so -1 is the last character, -2 is the next to last, etc.pt:o texto de _ entre as posições _ e _ , inclusive
Reports True if the first input string contains the second input string, otherwise false.
Comparison is case-independent by default; use USE CASE-INDEPENDENT COMPARISONS to change that.pt:o texto de _ antes de _
Reports the input text with lower case letters instead of capital letters in the input. Uses the user's locale's rules for case conversion.pt:em minúsculas _
