/*
In the following code segment we use the functions
void move(uint8_t desired_speed, uint8_t dir, uint16_t distance, uint8_t blocking)
and
void rotate(uint8_t desired_speed, uint8_t dir, uint16_t angle, uint8_t blocking)
The parameters have the following purposes:
move:
uint8_t desired_speed: The Speed the robot should try to maintain all the time
during the movement.
(but it will slow down a bit before it reaches the desired
distance)
uint8_t dir: The Direction the robot should move - this can be
FWD for Forwards or BWD for Backwards.
You can also use LEFT or RIGHT here, but this function
is not optimized for rotation - you should use rotate
instead!
uint16_t distance: The distance we want to move. The distance needs to be
given in encoder counts. You can use the macro DIST_MM()
to convert the distance from mm to encoder counts if you
have calibrated your Encoder sensors resoultion.
Maximum distance is 65000 encoder counts!
(not 65535 like you might have thought. There needs to be
a bit space to the top value... anyways - who wants to
move about 15m? ;) )
uint8_t blocking: This parameter sets if the function shall block the normal
program flow during the movement.
If the parameter is "true", the function will NOT quit
until the robot has moved the given distance!
ACS, Bumper, RC5 and other events are still processed and
not affected, but the main program will be blocked (s. below).
You can use "BLOCKING" instead of "true" and
"NON_BLOCKING" instead of false to make the code more readable!
rotate:
uint8_t desired_speed: Same as above.
uint8_t dir: Nearly the same as above, but here you should only
use LEFT or RIGHT as parameters even if you can pass
BWD or FWD to this function.
uint16_t angle The angle to turn. Attention: This rotation function is
not optimal for very small angles - it is optimized to
turn angles over 25°!
If you want smaller angles, you need to write your
own function!
And even for large angles this function is far away
from beeing perfect as the encoder errors for rotation
are rather big. You need to do some experiments to
optimize this for the surfaces you want to use the
Robot on. The encoders are mainly intended for very good
speed regulation and don't work too well for tracked
vehicles' dead reckoning. Not only for RP6 but for EVERY
tracked vehicle out there - even for those
with $10.000 price tag.
Measuring distances when moving straight forward works
OK - but not when rotating as there is a lot of tracks
slippery and you always don't move as far as you measured.
Solution: Use external sensors for rotation! Like
electronic compass, gyroscopes, optical mouse sensor or similar.
Also s. comments in next example!
To block or not to block:
If you set the "blocking" parameter to false, then the function will only set all
necessary parameters and quit - it will not wait until the movement has finished.
This code:
move(60, FWD, DIST_MM(300), false); // <-- non blocking
rotate(50, LEFT, 180, false); // <-- blocking
mSleep(5000);
would NOT work as intended! The Robot would NOT move 300mm and then turn 180°, instead
it would only turn 180°! And, if you remove the mSleep(5000) at the end, it would maybe
not even do this.
You always need to check if the movement has finished and if you can initiate the
next movement if you set the blocking parameter to false!
This:
move(60, FWD, DIST_MM(300), true); // <-- blocking movement
rotate(50, LEFT, 180, true); // <-- blocking rotation
would work like intended and the robot would move 300mm, turn 180° and stop.
This is equivalent to this:
move(60, FWD, DIST_MM(300), false); // <-- non-blocking movement
while(!isMovementComplete()) // Now we need to wait until the movement
task_RP6System(); // is finished before we go on.
// If you set blocking to true, the function
// does exactly this automatically.
rotate(50, LEFT, 180, false); // <-- non-blocking rotation
while(!isMovementComplete()) // Again, we need to wait for the
task_RP6System(); // movement (rotation) to be finished...
Of course, you do not need to wait for the movement to finish in a while-loop - you can
also check this in several different ways and you can do other things while the movement is
in progress. You will see some other ways in the next examples.
You can use the "isMovementComplete()" function for checking if the last movement is
complete.
There is also a function "stop()" that can be used to abort a movement, e.g. if one
of the sensors has detected an obstacle. But you do not need to use stop, you can also
initiate the next movement without performing "stop" before.
