No matter how much "better" it gets, having the platform move around the human is just a bad idea.
They'd be better off to have a fixed (i.e. non-moving) platform and put the robotics and mult-directional wheels into shoes the human wears (or probably big clunky wired boots for the first few designs).
By controlling the direction, speed, and/or friction of each wheel, they would be able to do the same thing as the moving platform.
Tilt/raise/lower the stationary platform (and add the corresponding friction/movement to the correct wheels) and you could simulate going up or down a hill.
I suspect there are 9 bazillion kooks writing books about earth-like planets and or extra terrestrial life using extremely limited data with a margin of error 100's of times larger then their data sample, wishful thinking, and pure "what will sell books" speculation.
Another tree hugger idea that has NO engineering behind it. Even if you could get the full output of those teeny tiny solar panels (and ya can't, they're wrapped around a cylinder which means half the panel will effectively be in the dark) there isn't enough "oomf" to charge the batteries. It's doubtful they even have enough to trickle charge them to maintain the battery once it's charged to full in a real charger.
And that's substantiated where? Ever see a grizzly fish LIVE salmon? Maybe they don't like to dive too deep and get a snoot full of water.

//damn tv commercials, now my butt knows it can make calls on purpose.
Like that's possible.
