That is fast...
The scout is pretty cool, and easy to get going. The commands are best learned by experiment.
On/Off button: self explanatory.
Run button: ditto.
Select button:Cycles you through motion menu, touch menu, light menu, speed of execution ( you will
hear a change in the frequency of the heartbeat cricket sound), Brick mode/Power mode, FX menu
(mostly sound themes), the question mark will give random motions in the move cycles.
Change button: Cycles through menu options, for example, with the motion menu column blinking
Use the select button to cycle through Fwd, ZigZag, Circle CW, Circle CCW, Loop A, Loop B, Loop AB.
Use the select button again to lock in your choice and move to the next menu column. Note: With all
The items in a menu column blinking, pressing select will SELECT NONE, and move to the next column.
This can be useful to isolate certain behaviors to see how they work. To clear all, hold On/Off for two
Seconds. This returns the Scout to "I just put in the batteries for the first time" mode.
The light sensor can be "trained" when you power on. Basically I think it saves for a median value the
light it first sees when it is turned on. If you turn it on in a dark room, you will never be able to find a dark
corner. If you are pointing it at a bright light, then the whole world will seem dark. I find that if I point it at
a brightly lit wall, then the light sensor turns "on" when pointed at a light, and turns "on" when pointed at
the dark. The light sensor LED will come on in both cases, with a little trilling sound
The scout will respond to 15 messages from a rcx brick.
0...stop momentarily
1...spin 450d ccw, back to 0d, resume path
2...spin, resume at about 30d ccw of original path
3...crazy dance, resume at about 30d ccw of original path
4...2 momentary stops
5...rev a bit, then resume
6...pivot 45d cw
7...pivot 45d ccw
8...brake R, L on Fwd
9...brake R, L on Rwd
10...brake L, R on Fwd
11...brake L, R on Rwd
12...stop momentarily
13...brake momentarily, and turn on red LED
14...same as above
15...turn off red LED
These are all based on simple forward behavior while testing, some of the routines seem to interact with
one another....
Have fun

 | | The Scout vs. the RCX
|
| I played with a Scout over the weekend, and build two of the models. Summary: If you like the RCX, skip the Scout. For $50 less, you get half as many parts, and a not really programmable controller with only two motor outputs, and no external light (...) (25 years ago, 20-Sep-99, to lugnet.robotics)
