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.
