X-rhex Robot Gets a Tail, Always Lands on Its Feet

The tiny Tailbot robot relies on a tail to control its balance. Now, the creators of the Tailbot and the RHex hexapod robot have teamed up to make the X-RHex Lite. The difference between this robot and the original Tailbot is that the XRL is about 60 times bigger, weighing 8.1 kilograms compared to the tiny Tailbot which only weighed 177 grams.
