I took it down as the routine I was using took out one of my foot servos!!!
I have now got two duff servos and am looking forward to seeing if I can make one good one from the two bad.

The foot servo just went limp during re-recording of the cilp. all of the gears are intact so I am guessing the motor has gone although there was no smoke or bad smell.

I have yet to investigate properly as I just swapped the servo out, but it seemed to fail to respond to the controller yet sounded fine on independant movement.

Marcus.

Ps. Took me about 45 minutes to swap out the foot servo including reconfiguring the stock servo case.

Still getting 'unavailable' from YouTube.....

Just re-uploaded as of 21:50, give it a few minutes.

=================================

As of 22:10 it is working.

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.

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!

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?

[onesandzeros]

hey DirtyRoboto
i really like the "Robonova RN1 Sonar Combat" video
thats awesome dude.

[Robo1]

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

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

[DirtyRoboto]

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.

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

[DirtyRoboto]

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

Marcus.
