I really don’t think this concept makes sense. Firstly, I don’t even know if the motion they show would even be physically possible with their proposed technology. In reality, it would be super heavy and would need a LOT of power.

Secondly, it’s a HUGE hazard. it would be incredibly bumpy, probably to the point of injury and/or throwing the rider off. Also, it’s just asking to crush someone’s legs.

Don’t get me wrong, I think rideable legged robots are cool as hell, but this configuration doesn’t make sense until we’re making Westworld style soft robots with fusion reactors or something, or advanced biotech. With near future tech, you’d either need to be sitting within or above the robot, and you’d probably want more legs for stability. If you really want to ride it like a horse I guess you could probably do an 8 leg design with 4 in front and behind the rider, out of leg crushing range.
