Hi.
Here's a tank I made during the weekend, it has radio controll so
beware LEGO purists ,)
http://www.brickshelf.com/cgi-bin/gallery.cgi?f=1860
I used a five channel radio, five servos, five polarity switches and
five motors to make this work. It has two motors for drive, left and
right track, one motor for spinning the turret (360-motion), one
micromotor for raising the cannon and one micromotor as a trigger.
The series of thumbnails is from my videocamera that was placed on a
tripod and never moved, so all movement in the pictures is from the
tank. I'll make some mpeg's of this when I get my RainbowRunner
working okay.
It's good fun to play with and I have so far scared three of my
co-workers in the office by steering it into their offices and
shooting at them (suprise attacks) :)
I named it Lynx Mk I since it has winter camouflage and could be
improved quite a bit (Mk II). It takes about 30 seconds to raise/lower
the cannon between it's extends for examlpe.
One cool feature is that I can spin the turret in one direction and
let one track spin the tank in the other, this gives an illusion of
"Target tracking" (the cannon points at a goal even as the tank moves
about). This is illustrated in the photo labeled target_tracking.jpg.
turn.jpg displays the movement when both tracks are reversed to
perform a tight "on the spot" turn and wide_turn.jpg is one track
only.
I'll take some more pics when taking it apart and also make some
schematics for the control etc..
