Anything is possible with Vex kits! I haven't built any walking Vex robots (yet...
), but I have built walking Lego Mindstorms robots. The four and six legged ones were easier to stabilize while walking. The two legged one required me to shift the center of gravity while it walked. Building a two-legged Vex robot will need a shifting COG; the COG will always need to be over the leg that is on the ground. A four-legged robot will need a COG that is centered over the two legs in contact with the ground. A six-legged robot should never fall over, since three legs should be in contact with the ground at all times.
