    I don't want arial photography, I want to launch a robot a great
distance, have it land, deploy, and start taking pics.  Similar to the
pathfinder mission, but on (obviously) a much smaller scale.  I was
wondering if anybody had built a container that would cushion the impact
for the robot, etc..

An interesting subproblem here (and one that more people would probably
consider tackling) is building the container and robot.  The container could
land in any orientation (unless heavily weighted on one side, but that makes
launching via a rocket more difficult), and the robot will need a way to
open the container then be able to start wandering.  Again, the difficult
part here is that the robot could be oriented in any manner and would need
to be able to recover.

I think that a simpler and safer (but more expensive) launch vehicle might
be a model airplane.  The RCX could be taken to a location via airplane,
then dropped with a parachute at the operator's command.  At this point you
only need to worry about the impacts on your RCX from landing (softly, via
the parachute) and not from takeoff.  I believe that model airplanes also
have greater lifting power then model rockets, but I'm not an expert here.

Dropping the RCX from a kite would be the cheapest option, but you don't
have as much control over the drop point.  It would depend a lot on the
current winds.

(...) Two other alternatives would be a weather balloon and a small plane. I've dropped parachute jumpers from my Cessna and under the right conditions might be willing to drop someone else's RCX. The maximum height would be about 3 1/3 mile up; and (...) (25 years ago, 4-Jan-00, to lugnet.robotics)
