i really do not wan to bring logic into this thread but i really nid to drop u some insight. There is so much fail in that statement its not even funny.

mud? u leg will be equally as stuck. Hav u read bout Operation Barbarossa and the circumstances that leads to its failure? Every1 get bog down in the mud be it humans or the tanks, so how is limb superior? Hav u try wading through water? Even just plain water, u will struggle to move about let alone mud and all of its impurities. Try running on the beach submerge urself waist deep and run, good luck.

wet surface dry surface, since when wheels hav a problem with that? Last i check my wheels operate just fine. If u say there is plenty of car crashed in wet condition sure, thats true but is that the wheels fault or the idiotic driver hu duno car control and the basics of emergency braking? Heck if u waterprof ur car ur wheels can still function fully submerge, ur leg on the other hand will struggle to even stand upright.

jump? Do u kno the purpose of jumping? hu needs jumping when u can adjust ur height via hydrolics? And if u wan to be pedantic, hu says u cant jump with wheels? Ever seen american modified cars with sup up hydrolics?

Wheels can operate in condition far beyond what ur leg can withstand. on aircraft during takeoff it can achieve 400km/h. Come back when u can run 100. Wheels can operate beyond boiling point, ur leg on the other hand will be cooked at 100.

Let take this beyond biology shall we, lets say u r building an object and ur goal is to move from point A to point B. So how many moving parts is required for a leg? u nid an ankle, knee, toes, and hip. Ok u nid to move each of those so u nid a servo for each joint. u nid atleast a pair of legs to accomplish its intended function so multiply it by 2, then u nid a gyroscope to remain upright and u nid a computer to calculate the shifting of center of gravity. Ok how bout Wheels? an engine, an axle and 4 round object. Assume ur goal is just a straight line, i can build a wheel and finish faster then u can build a leg and at a fraction of the cost. My wheels can repeat the course millions of time without hickup u think with so much moving parts ur leg can achieve the same speed, consistency and reliability?

Oh and lets take square cube law into equation. As a shape grows in size, its volume grows faster than its area. u wan to build a human size leg sure, hey how bout let extrapolate it and build a monster truck tires size leg shall we? Why not right? If u can make monster truck size wheel surely u can make monster truck size leg. Go ahead try it.

if u say limbs can tackle obstacle like say climbing the stairs, i can tell u wheels of similar size can do the same. Heck with some smart configuration, small wheels can also do the same.

so u tell me what advantage do limbs have? If u say its for intimidation or for familiarity sake, sure u'll hav a point cuz that has alot to do with human psychology, we r a very cautious creature when dealing with things that r unfamiliar to us, we can be very apathetic if the said object looks nothing like us but if it does look like us then we become more receptive. From a psychological standpoint humanoid looking machines will make sense but from a practical standpoint, nope it has virtually no advantage to justified it.

U can believe all u wan but laws of physic doesn't agree with u.

hover fly those hav nothing to do with legs and wheels. U can hav wheels even with flight or hover capability. It'll just be a dead weight, it'll hinder its flight or hover capability, but its not gonna prevent it from doing so.

can wheels jump over a falling trees? The point of ur argument is not jumping over something, its just the act of jumping itself. Once u can jump the only barrier towards jumping over anything is just the amount of energy u introduce to the system. So in essence ur point of contention is can wheel jump, YES it can. Look up on american sup up hydrolic car modification.

again why the need for jumping? If u can fly or hover or adjust its height via hydrolics, jumping is moot.

if u wan to be pedantic, nothing can evade a lazer beam. Nothing is faster then speed of light, u can never respond in time to a lazer beam to dodge it. so dodging a lazer beam is moot since that is pure fiction not applicable in real life. Not to mention its mass would prevent any rapid movement. In real life all this jumping dodging lazer beam is not possible.

as u said there is alot of moves, involving alot of joints, alot of servos, alot of computation, alot of stuff to happen at the right time for it to function. Alot of stuff means alot of problem. The more moving parts that u hav the more things can go wrong the less reliable it gets. Why do u wan to make things unreliable? In a war machine that is suppose to take alot of beatings, this is a dumb idea. A disaster waiting to happen.

from a practical standpoint; ignoring the fact the a giant robot will just b nothing but a big bullseye with a sign saying shoot me; if u replace all the weapons with conventional mounted design and replace the leg with wheels (square cube law makes this impossible but lets ignore it for argument sake) its be far more efficient, cost less to maintain and develop, much more reliable, move faster on terrain, and u can produce more of it with the same budget.

i kno what u wan is a humanoid looking giant robot of doom, however humanoid form its just not practical and the laws of physic do not allow it. Its fine and all in a fictitious world with its own fictitious physics, just dun let it cloud u in the real world. Enjoy it as a from of entertainment but kno that it defy the law of physics in almost all aspect. Dun bring real world logic into entertainment, it'll never work.
