It might be possible to gradually wind up a bungee cord and then abruptly
release it.

That would permit a gradual conversion of electrical to mechanical energy at a
rate the the RCX permits, while still allowing high power for the short time
necessary to jump.

Don't forget the suspension system. All that stored mechanical energy (most of
it, anyway) goes into potential energy at the top of the hop, and back into
kinetic energy at good old Planet Earth.

What are the first two rules for flying small planes? 1: Don't hit anything
(like a planet). 2. Arrive alive. They apply here.

Yeah! The bungee idea would work! Combine that with the pogo idea- I'm
thinking for balance just put the bot inside a tripod or pyramid- basically
the pogo stick hangs from the top of the pyramid. Motors could angle it, then
when the bungee shot the pogo, the bot would jump in that direction. The
pyramid could be your shock absorber.
