The flic flac spider has a hilarious way of moving, just keeps doing cartwheels to get from point 1 to point 2. Maybe it's to avoid touching hot desert sand for too long? Anyway, it's pretty cool that this inspired the design of a robot, so now it can roll really fast to travel long distances but when it needs more precise motion then it can start using its legs. I guess what I'm not certain about is what this robot does after it gets to its destination; maybe put a spycam on there to scout, or just a practical joke? Or it could just be a mini vacuum cleaner, catching dust instead of insects...
