Hi Marco

The RCX is slung underneath the "glider" (actually a 2 meter delta stunt kite).  It has
one micromotor plugged into OUT_B (i.e., the micromotor contacts are fitted directly onto
the OUT_B contacts so the center of the motor's rotation is vertically upwards).  A cam is
fitted on top of the mocromotor with 2-stud axle -- the far end of the cam is attached to
bridle lines which go to the left and right spars of the delta.

I don't directly control the RCX, it is programmed to to stay straight for one second, and
then shift the cam slightly to the left -- this shifts the wieght of the RCX relative to
the center of gravity of the kite,  thus putting the kite into a banking spiral.  The RCX
also beeps every half second so that I have a way of calculating the flight time.  If you
want more info, I can post a dat of the RCX to one of the CAD sections.

Cheers

JP

I am spending a few hours building the new supercar (8448) and I turned on the robot cam to watch (its Lego TV!). I am still testing the live robot cam so check it out and help me test the connection and setup at (URL) Thompson (URL) (25 years ago, 6-Nov-99, to lugnet.robotics)

JP, How do you attach the RCX to the kite? Is it taped,or does it use legos? Andy (25 years ago, 6-Nov-99, to lugnet.robotics)

I was really skeptical of this whole concept when I saw your first post, but this sounds GREAT! I'd love to see your creation in .dat form. Is the micro motor strong enough to recover from a spiral as well? Some specs on your kite and bridle set up (...) (25 years ago, 6-Nov-99, to lugnet.general, lugnet.robotics)

Dear All Wow, thanks for the interest. I have taken some pictures of the RCX in flight today -- I have not had them developed yet, so don't know how they look. Anyway, I'll keep shooting until I get some decent ones and post them on the web (...) (25 years ago, 7-Nov-99, to lugnet.general, lugnet.robotics)
