I bought one of the big green ugly things. It does have the throwbot
parts!
It also has two sets of rack steering, a black turntable and a couple of
the
larger bevel gears. Plus a good amount of other useful technic stuff.
And if anyone still thinks discussion of set contents is off subject
for
this robotics area, they're wrong. I buy sets for the
<underline>sole</underline> purpose of
using the parts to augment RIS. So knowing what parts are out there is
very important to me.
For example, the throwbots things have some very handy spherical
joints,
which can actually be made a lot more useful by carefully cutting them
away from the fake legs/arms they are joined to. You end up with a
sphere
on a short 1/2 inch piece of cross axle. When combined with more common
axle joiners of various kinds, complex variable geometry structures can
be easily built. And the throwbot kits are only $5 - $6 apiece even if
you
have to discard the plastic box that comes with it. You're still left
with worm housings with a quadrant gear which can mesh with another of
the same kind to make a very robust shoulder/arm joint! I bought a
couple of pairs of these sets. (They're the ones called Slizers)
