Are you using the AN pin on the MaxSonar for the readings?

All of my moves are captured freehand. I couldn't imagine doing it on a stand!

I am just about to start coding an unusual routine I guessed it could be done and I have been racking my brain for ages thinking how. Last night I think I cracked it. I am gonna try implimenting right now as I have been itching to do this all day.

thanks for the code Marcus.

just dropped coin on a hitec rn1 stand, so testing sensors/experimenting with/creating moves should be (less faff) more enjoyable now…

previously it was one hand on RN1, one hand typing code, one hand moving limbs, one hand getting the usb adptor working…

Cool stuff. The Hitec Sonar unit seems to work better with the RN-1 then the old SRF units we all tried in the early days. Must try to get one.

Excellent work

I will PM you with my "Sonar Combat" test routine. Giz about 10 Min.

top man (again), thanks.

I have the same sonar module, so i guess your code should work fine.
If i get time i'll have a crack at it tonight

My sonar is the MaxSonar EZ-1. It uses analogue so will not respond to the SONAR command.

I have it on AD(5) so do this.

DIM son AS INTEGER (could do this as byte really)
for every time I need to read the sonar value I do the following.

son = AD(5)

Then you might try this.

sonar:
son = AD(5)
IF son > 50 THEN GOTO sonar
IF son < 50 AND son > 30 THEN GOTO move_one
IF son < 30 AND son > 20 THEN GOTO move_two
. and
. so
. on
GOTO sonar

I hope this is of help.

Marcus.

hi robo1,
thanks, i'd figured that far, but am not sure what values to assign to "x" and therefore what the upper and lower limits are.

if i get time over christmas i'll probably try the trial and error method but was hoping for a "lazyman's solution" from dirty

plingboot - if you can read the signal then you need something along the lines of,

it(signal > x)[
do this
}

you can have a couple of these loops so that for different reading you RN1 exacutes diffent code.

hope this helps bren

top, top stuff.

i managed to get my sonar working but have absolutely no idea how to interpret the signal and turn it into meaningful code (like this).

any chance of some code, or a mini tutorial?

Nice work Dirty. I especially like the the arms waving in the first video!
The second video looks like he responds very much in real time.
Excellent, keep'em coming!

Just uploaded part II.
This is an experiment in sonar and combat.
At differing distances the RN1 goes into more or less agressive stances culminating in an attack if within range.
