I wouldn't call that an argument Timothy (no offence ment) since the prim=
e
objective of designing a car is not how to make it keep it's balance. In =
a
car it is an implicit assumption that the weight / height distribution is=
in
favor of balancing which makes this a secondary concern.
However, have you guys seen that MIT robot that keeps it balance
dynamically? It has two straight legs, no kneejoints, no feet or whatever.
It walks in a pogo-stick style manner which means it gives a jump each ti=
me
one stick touches the ground. It is not capable of standing still since i=
t
lacks an area on which to stand. It can - however - somersault and still
keep it's balance afterwards. If you need an URL I'll see if I can find i=
t
again.
