That doesn't look terribly optimized...

I'd like to see you do better. Remember, your parameter is to create a legged robot that is capable of moving over loose and shifting granular surfaces where wheels and more standard insectoid-bot feet will get stuck.

That's not a picture of a robot.  That's just a picture of some basic shapes that might be used in designing robots.  Like the one in the video.

I guess Subby was passed over for that job at NASA for being overqualified. I'm sure he knows better than some dumb "researchers."

Solving problems requires differential thinking. Kids have it and most start to lose that ability as they get older, and I noticed that one of the first things they say to others when they lose that ability is, "That's stupid."

New field of research didn't instantly produce a polished product? Fail.

Improved? It doesn't even have ONE vagina.

What the hell?  Damn martians can build their own damn robots!  Wasting my good tax money on this shiat.

That's not a robot....

THIS is what a robot is supposed to look like:

Pretty sure there is a ted talk about this from like 2005.  Same robot and everything.

Pretty sure that's an Android.

The epitome of the old adage:  If its stupid but it works, it isn't stupid.

People thought the Apollo lunar landers looked freaky at first too.  But they did the job, and in the end, that's what really mattered.

Actually, the half-circle feet were one of many tests, and the most successful in the video, in both speed and maintaining a straight line of travel.

It makes sense, really, as the foot rotates, the curve of the foot gives it a steady push slightly up and forward, keeping the bot moving and above the sand.  The other designs the angle of momentum varies as the foot rotates around, creating oscillation that disrupts the robot's ability to move in a consistent manner.

This is going to be the best Martian prom ever.

I dunno, wheels seem like the best approach.  Why reinvent the wheel?

So this never happens to another robot:

Yeah, build powerful robots for Martians.

That'll totally work out for everyone....

Except those feet didn't keep it on top of the sand or seem very efficient at propelling it forward. Legs are great over rough terrain because they can change length to work around high and low spots. With loose stuff like sand you need lots of surface area to keep on top of it. Legs and feet don't typically have that.

You could have put some wide tires on that thing, kept it on top if the sand, and made it faster. It's very hard to beat the surface area if wheels.

Also, techincally if a person is not controlling it, it isn`t a robot either as robot comes from robota meaning servitude so if it is not in servitude then it`s not a robot. Old wooden face didn`t seem to have any control over the thing in the film. Maybe an automaton.
