This pages lists the issues with the current Learning Computing with Robots: Uses Calico Python + Scribbler or Scribbler2

Errata 2011

1. Page vi (and throughout): it might be more clear if the Fluke isn't defined as a dongle, but the USB is. Otherwise, most people will have two dongles to distinguish. Perhaps call it a "board"...
2. Page vi: MACOS is usually Mac OSX
3. Page viii: define IDE
4. Page 7: maybe mention http://CalicoProject.org/ rather than wiki.roboteducation.org/
5. Page 12: consider using TIME in forward(SPEED, TIME) ...
6. Page 51, 53: speak(..., 0) the zero isn't necessary as it is the default
7. Page 63 (and throughout): bad quotes (Word non-ascii) in example code
8. Page 68, 100: telling forward(1.0) in a loop doesn't do anything, perhaps:

   for t in timer(3.0):

   if randomNumber() < .5:

   forward(1.0)

   else:

   backward(1.0)

   stop()

9. Page 76: random and randint relay on importing random; randomNumber() is in Myro
10. Page 122: sometimes ask("What port?") is used to get a comport, sometimes just a number; should NOT assume "com" as that is a windows-only thing
11. Page 125: getStall() won't work if the robot isn't moving
12. Consider using int(ask()) instead of int(ask()) or float(ask()) as that makes it more clear what it is doing.
13. Page 158: "remember to import Graphics" -> should be 'remember to "from Graphics import *"'
14. Page 158: you can also getColorNames() rather than Google
15. Page 159: you can use Dot(p)
16. Page 168: computer.beep() doesn't currently work
17. Page 176: Point() doesn't have anything to do with the Window, just with objects
18. Page 176: Polygon() doesn't take a list, just points
19. Page 184: Can't currently save a single image as a gif, only a list
20. Page 186: missing quote on "black
21. Page 187: setRGB(pixel, (0, 0, 0)) should be setRGB(pixel, 0, 0, 0) [can't seem to fix in Graphics/Myro source code!]
22. Page 218: missing "import copy"?
23. Page 277: "That is, execution of subsequent commands can be done prior to the text being spoken." should be: "That is, execution of subsequent commands can be done while the text is being spoken."
