I was thinking of something like that, but then I'd have to work out
there to put the "weight" of the pendulum at any given time, and I have
no idea where to start with those calculations. And also...I'm not sure
which sort of joint I'd use for this, as an amotor is more than likely
to cause some of the issues I experiened before.
I can forsee some problem arising from this though, the first being the
bike motion osccilationg back and forth between the desired lean angle
and the posssibility that the bike may fall over, which is not really
what I want.
