In the world of robots, bipedal walking was certainly an heretical existence.
No matter if it was from the difficulty of writing action programs, the automatic adjustment of the center of gravity when walking on two feet, or balance control during high-speed movement—since the invention of robots, the development history of bipedal walking robots was like a relentless declaration of just how unreasonable human beings are as creatures, with all kinds of accumulated difficulties and obvious contrasts mocking humanity's vain obsession with bipedal locomotion.
To conclude, the only places suitable for bipedal walking robots were museums, movies, books, and cartoons.
Therefore, aside from tracks, wheels, rotors, rockets, and jet engines, the most common form of robot movement on the ground was definitely multi-legged walking, which was structured similar to arthropods.
