I've experimented with those wires and I believe that would require a lot of power to operate for very little return in function with that particular design. It would work a lot better using actual legs even using those wires. I really don't believe this design would be more effective than using motors.

The point of this is not efficiency, but robustness and ease of manufacture (think of something you could print on Mars and needs to function pretty much indefinitely)

it would still be better with legs and those wires use a lot of current.

IMO, the legs on this robot seem to be very capable moving along on a sandy, snow and icy environment, much like the runners on a sled, but bendable. On a rocky or stony surface, not so much.
