RHex robot

The RHex Robot from Boston Dynamics come with appendages that provide it with wheel-like mobility as well as leg-like traction when necessary. For those who constantly work in an aquatic environment, you can always swap its legs for paddles without worrying about the RHex fizzling out courtesy of its completely sealed body. It can be controlled from over 500 meters away with a remote control, and comes mounted with both front and rear cameras.
