Subject: Re: efficient launcher?
Yes Phillip,
I have an idea... What about using a long arm like a catapult... The arm
could also be used to right the bot too... I saw a bot that used an arm to
pole vault over obstacles... But I don't know were it is now???
Another idea I had, the other day... Was for righting a bot... I was
watching my son playing with a click beetle... Why not make the body hinged
and have it snap like a click beetle??? Click one way to make it jump and
the other to make it flip back right side up???
Timothy...
